EXECUTIVE SUMMARY
The proposed Reliability Standards are designed to augment NERC’s cybersecurity
Critical Infrastructure Protection (“CIP”) Reliability Standards to further mitigate cybersecurity
risks associated with the supply chain for BES Cyber Systems, consistent with Order No. 829. In
that order, the Commission found that supply chains for information and communications
technology and industrial control systems present risks to BES security, providing various
opportunities for adversaries to initiate cyberattacks. 8 The Commission stated that “[t]he targeting
of vendors and software applications with potentially broad access to BES Cyber Systems marks

a turning point in that it is no longer sufficient to focus protection strategies exclusively on postacquisition activities at individual entities.” 9 The Commission thus directed NERC “to develop a
forward-looking, objective-based Reliability Standard to require each affected entity to develop
and implement a plan that includes security controls for supply chain management for industrial
control system hardware, software, and services associated with bulk electric system operations.”10
The proposed Reliability Standards address the Commission’s directive in Order No. 829
and enhance the cybersecurity posture of the electric industry by requiring Responsible Entities 11
to take additional actions to address cybersecurity risks associated with the supply chain for BES
Cyber Systems. 12 Consistent with Order No. 829, the proposed Reliability Standards focus on the
following four security objectives: (1) software integrity and authenticity; (2) vendor remote
access protections; (3) information system planning; and (4) vendor risk management and
procurement controls. Collectively, the requirements in the proposed Reliability Standards are
designed to:
•
Reduce the likelihood that an attacker could exploit legitimate vendor patch management
processes to deliver compromised software updates or patches to a BES Cyber System.
•
Address vendor remote access-related threats, including the threat that vendor credentials
could be stolen and used to access a BES Cyber System without the Responsible Entity’s
knowledge, as well as the threat that a compromise at a trusted vendor could traverse over
an unmonitored connection into a Responsible Entity’s BES Cyber System.
•
Address the risk that Responsible Entities could unintentionally plan to procure and install
unsecure equipment or software within their information systems, or could unintentionally

As used in the CIP Reliability Standards, a Responsible Entity refers to the registered entities subject to the
CIP Reliability Standards.
12
The CIP Reliability Standards currently include a number of requirements that help mitigate supply chain
risks. See Comments of the North American Electric Reliability Corporation In Response to Notice of Proposed
Rulemaking, at 15-16, Docket No. RM15-14-000 (Sept. 21, 2015).

fail to anticipate security issues that may arise due to their network architecture or during
technology and vendor transitions.
•
Address the risk that Responsible Entities could enter into contracts with vendors who
pose significant risks to their information systems, as well as the risk that products
procured by a Responsible Entity fail to meet minimum security criteria.
•
Address the risk that a compromised vendor would not provide adequate notice of security
events and vulnerabilities, and related incident response to Responsible Entities with
whom that vendor is connected.
Specifically, proposed new Reliability Standard CIP-013-1 requires Responsible Entities
to develop and implement plans to address supply chain cybersecurity risks during the planning
and procurement of high and medium impact BES Cyber Systems. As discussed in greater detail
below, proposed Reliability Standard CIP-013-1 improves reliability by requiring Responsible
Entities to implement processes to: (1) identify and assess cybersecurity risks to the BES from
vendor products and services in their planning activities for high and medium impact BES Cyber
Systems; and (2) include specified security concepts in their procurement activities for high and
medium impact BES Cyber Systems.
Additionally, the proposed modifications in CIP-005-6 and CIP-010-3 bolster the
protections in the currently-effective CIP Reliability Standards by addressing specific risks related
to vendor remote access and software integrity and authenticity, respectively, in the operational
phase of the system life cycle. Pursuant to Requirement R2, Parts 2.4 and 2.5 of proposed
Reliability Standard CIP-005-6, Responsible Entities must have one or more methods for: (1)
determining active vendor remote access sessions (Part 2.4); and (2) disabling active vendor
remote access (Part 2.5). The security objective of these requirement parts is to control vendor
remote access to mitigate risks associated with unauthorized access.
Further, pursuant to Requirement R1, Part 1.6 of proposed Reliability Standard CIP-0103, prior to installing software, Responsible Entities must verify the identity of the software source
4
and the integrity of the software obtained by the software sources, when methods are available to
do so. The security objective of verifying software integrity and authenticity is to ensure that the
software being installed in the BES Cyber System was not modified without the awareness of the
software supplier and is not counterfeit.
The proposed Reliability Standards would add to the defense-in-depth approach of the CIP
Reliability Standards by strengthening the required protections that help mitigate supply chain
risks. For the reasons discussed herein, NERC respectfully requests that the Commission approve
the proposed Reliability Standards as just, reasonable, not unduly discriminatory, or preferential,
and in the public interest.
Supply chain management, however, is a complex global issue. Supply chains for
information and communications technology and industrial control systems are long and
multidimensional, involving numerous parties in a multitude of countries across the globe.
Registered entities typically rely on a number of vendors and contractors that may use multiple
third-party suppliers for components used in their products or technologies. Multiple entities across
the globe may participate in the development, design, manufacturing, and delivery of a single
product purchased by a registered entity. As mandatory Reliability Standards under Section 215
of the FPA have limited applicability – they cannot directly impose obligations on suppliers,
vendors, or other entities that provide products or services to registered entities 13 – NERC
Reliability Standards should not be expected to mitigate all risks inherent to the global supply
chain.
13
As the Commission stated in Order No. 829 (at P 21), “any action taken by NERC in response to the
Commission’s directive to address the supply chain-related reliability gap should respect ‘section 215 jurisdiction by
only addressing the obligations of responsible entities’ and ‘not directly impose obligations on suppliers, vendors or
other entities that provide products or services to responsible entities.’”
5
In conjunction with the adoption of the proposed Reliability Standards, the Board issued a
series of resolutions directing NERC to continue working with industry and vendors on supply
chain issues, including preparation for implementing the proposed Reliability Standards, further
studying of supply chain risks, and continued information sharing, among other activities, as
further discussed below. 14 To that end, NERC is committed to using its many reliability tools –
e.g., guidelines, training exercises, alerts, information sharing and analysis – to support industry’s
efforts to mitigate supply chain risks and engage vendors to identify and address emerging supplychain risks.

mandatory Reliability Standards, subject to Commission approval. Section 215(b)(1) of the FPA
states that all users, owners, and operators of the Bulk-Power System in the United States will be
subject to Commission-approved Reliability Standards. 16 Section 215(d)(5) of the FPA authorizes
the Commission to order the ERO to submit a new or modified Reliability Standard. 17 Section
39.5(a) of the Commission’s regulations requires the ERO to file for Commission approval each
Reliability Standard that the ERO proposes should become mandatory and enforceable in the
United States, and each modification to a Reliability Standard that the ERO proposes to make
effective. 18
The Commission has the regulatory responsibility to approve Reliability Standards that
protect the reliability of the Bulk-Power System and to ensure that such Reliability Standards are
just, reasonable, not unduly discriminatory, or preferential, and in the public interest. Pursuant to
Section 215(d)(2) of the FPA and Section 39.5(c) of the Commission’s regulations, the
Commission will give due weight to the technical expertise of the ERO with respect to the content
of a Reliability Standard. 19

Development) of its Rules of Procedure and the NERC Standard Processes Manual. 21 In its ERO
Certification Order, the Commission found that NERC’s proposed rules provide for reasonable
notice and opportunity for public comment, due process, openness, and a balance of interests in
developing Reliability Standards and thus satisfies certain criteria for approving Reliability
Standards. 22 The development process is open to any person or entity with a legitimate interest in
the reliability of the Bulk-Power System. NERC considers the comments of all stakeholders.
Further, a vote of stakeholders and adoption by the Board is required before NERC submits the
Reliability Standard to the Commission for approval.
C.
Order No. 829 Directives
As noted above, in Order No. 829, the Commission directed NERC to develop a new or
modified Reliability Standard that addresses supply chain risk management for industrial control
system hardware, software, and computing and networking services associated with BES
operations. The Commission stated that the new or modified Reliability Standard is intended to
mitigate the risk of a cybersecurity incident affecting the reliable operation of the Bulk-Power
System. 23 The Commission further specified:
[W]e direct NERC to develop a forward-looking, objective-based Reliability
Standard to require each affected entity to develop and implement a plan that
includes security controls for supply chain management for industrial control
system hardware, software, and services associated with bulk electric system
operations. The new or modified Reliability Standard should address the following
security objectives…: (1) software integrity and authenticity; (2) vendor remote
access; (3) information system planning; and (4) vendor risk management and
procurement controls. In making this directive, the Commission does not require
NERC to impose any specific controls, nor does the Commission require NERC to
propose “one-size-fits-all” requirements. The new or modified Reliability Standard

should instead require responsible entities to develop a plan to meet the four
objectives, or some equally efficient and effective means to meet these objectives,
while providing flexibility to responsible entities as to how to meet those
objectives. 24
For the first objective, software integrity and authenticity, the Commission specified that
the “new or modified Reliability Standard must address verification of: (1) the identity of the
software publisher for all software and patches that are intended for use on BES Cyber Systems;
and (2) the integrity of the software and patches before they are installed in the BES Cyber System
environment.” 25 The Commission stated that “[t]his objective is intended to reduce the likelihood
that an attacker could exploit legitimate vendor patch management processes to deliver
compromised software updates or patches to a BES Cyber System.” 26
For the second objective, vendor remote access, the Commission specified that the “new
or modified Reliability Standard must address responsible entities’ logging and controlling all
third-party (i.e., vendor) initiated remote access sessions,” for both user-initiated and machine-tomachine vendor remote access. 27 The Commission explained that “this objective addresses the
threat that vendor credentials could be stolen and used to access a BES Cyber System without the
responsible entity’s knowledge, as well as the threat that a compromise at a trusted vendor could
traverse over an unmonitored connection into a responsible entity’s BES Cyber System.” 28
Further, the Commission stated that the “controls adopted under this objective should give

responsible entities the ability to rapidly disable remote access sessions in the event of a system
breach.” 29
For the third objective, information system planning, the Commission specified that the
“new or modified Reliability Standard must address how a responsible entity will include security
considerations as part of its information system planning and system development lifecycle
processes,” including “a responsible entity’s CIP Senior Manager’s (or delegate’s) identification
and documentation of the risks of proposed information system planning and system development
actions.” 30 The Commission explained that this “objective is intended to ensure adequate
consideration of these risks, as well as the available options for hardening the responsible entity’s
information system and minimizing the attack surface.” 31 This objective “addresses the risk that
responsible entities could unintentionally plan to procure and install unsecure equipment or
software within their information systems, or could unintentionally fail to anticipate security issues
that may arise due to their network architecture or during technology and vendor transitions.” 32
For the fourth objective, vendor risk management and procurement controls, the
Commission specified that the “new or modified Reliability Standard must address the provision
and verification of relevant security concepts in future contracts for industrial control system
hardware, software, and computing and networking services associated with bulk electric system
operations.” 33 The Commission further stated that NERC must address the following topics for
this objective: (1) vendor security event notification processes; (2) vendor personnel termination

notification for employees with access to remote and onsite systems; (3) product/services
vulnerability disclosures, such as accounts that are able to bypass authentication or the presence
of hardcoded passwords; (4) coordinated incident response activities; and (5) other related aspects
of procurement. 34 The Commission explained that this objective “addresses the risk that
responsible entities could enter into contracts with vendors who pose significant risks to their
information systems, as well as the risk that products procured by a responsible entity fail to meet
minimum security criteria” and “the risk that a compromised vendor would not provide adequate
notice and related incident response to responsible entities with whom that vendor is connected.” 35
In addition, FERC specified that the new or modified Reliability Standard should include
“a periodic reassessment of the utility’s selected controls,” by requiring the Responsible Entity’s
CIP Senior Manager to review and approve the controls adopted to meet the specific security
objectives identified in the Reliability Standard at least every 15 months. 36 The Commission
explained that this periodic assessment “should better ensure that the required plan remains up-todate, addressing current and emerging supply chain-related concerns and vulnerabilities.” 37
D.
Development of the Proposed Reliability Standards
As further described in Exhibit G hereto, following the issuance of Order No. 829, NERC
initiated a Reliability Standard development project, Project 2016-03 Cyber Security Supply Chain
Risks Management (“Project 2016-03”), to address the directives from Order No. 829. On January
19, 2017, NERC posted the initial draft of proposed Reliability Standard CIP-013-1 for a 45-day
comment period and ballot. The initial ballot did not receive the requisite approval from the

registered ballot body (“RBB”). After considering comments to the initial draft, NERC posted a
second draft of CIP-013-1 for another 45-day comment period and ballot on May 2, 2017.
Concurrently, NERC posted initial drafts of CIP-005-6 and CIP-010-3 for a 45-day comment
period and ballot. The subject of the modifications in CIP-005-6 and CIP-010-3 were included in
the initial draft of CIP-013-1. The second draft of CIP-013-1 received the requisite approval from
the RBB with an affirmative vote of 88.64%. The initial drafts of CIP-005-6 and CIP-010-3 also
received the requisite approval from the RBB with an affirmative votes of 89.84 % and 82.92%,
respectively. NERC conducted 10-day final ballots for these proposed Reliability Standards, which
received affirmative votes of 84.19% for CIP-013-1, 88.79% for CIP-005-6, and 81.4% for CIP010-3. The Board adopted the proposed Reliability Standards on August 10, 2017.
IV.

12
A.
Purpose and Overview of the Proposed Reliability Standards
As noted above, the purpose of the proposed Reliability Standards is to enhance the
cybersecurity posture of the electric industry by requiring Responsible Entities to take additional
actions to address cybersecurity risks associated with the supply chain for BES Cyber Systems.
The CIP Reliability Standards currently include a number of requirements that help mitigate supply
chain risks. 38 As discussed in Order No. 829, however, security issues associated with potential
supply chain disruption or compromise present a significant threat to the BES and increased
attention should be focused on minimizing the attack surfaces of information and communications
technology products and services procured to support BES operations. 39 To that end, the proposed
Reliability Standards are designed to augment the existing controls required in the currentlyeffective CIP Reliability Standards that help mitigate supply chain risks.
As discussed further below, proposed Reliability Standard CIP-013-1 focuses on the
planning and procurement phases of BES Cyber Systems, requiring Responsible Entities to
develop and implement plans to address supply chain cybersecurity risks during the planning and
procurement of high and medium impact BES Cyber Systems. The security objective of the supply
chain cybersecurity risk management plans is to ensure that Responsible Entities consider the
security, integrity, quality, and resilience of the supply chain, and take appropriate mitigating
action when procuring BES Cyber Systems to address threats and vulnerabilities in the supply
chain. As discussed below, the supply chain cybersecurity risk management plans must include
processes to: (1) identify and assess cybersecurity risks to the BES from vendor products and
services; and (2) include specified security concepts in their procurement activities for high and
38

Rulemaking, at 15-16, Docket No. RM15-14-000 (Sept. 21, 2015).

medium impact BES Cyber Systems, including (i) vendor security event notification processes,
(ii) coordinated incident response activities, (iii) vendor personnel termination notification for
employees with access to remote and onsite systems, (iv) vulnerability disclosures, (v) software
integrity and authenticity, and (vi) coordination of controls for vendor remote access.
Additionally, the proposed modifications in CIP-005-6 and CIP-010-3 address specific
risks related to vendor remote access and software integrity and authenticity that are not already
addressed in the currently-effective CIP Reliability Standards. Pursuant to Requirement R2, Parts
2.4 and 2.5 of proposed Reliability Standard CIP-005-6, Responsible Entities must have one or
more methods for: (1) determining active vendor remote access sessions (Part 2.4); and (2)
disabling active vendor remote access (Part 2.5). Further, pursuant to Requirement R1, Part 1.6 of
proposed Reliability Standard CIP-010-3, prior to installing software, Responsible Entities must
verify the identity of the software source and the integrity of the software obtained by the software
sources, when methods are available to do so.
B.
Applicability and Scope of the Proposed Reliability Standards
1) Applicable Functional Entities and Facilities
Consistent with the Commission’s FPA section 215 jurisdiction and Order No. 829, 40 the
proposed Reliability Standards apply only to registered entities and do not directly impose
obligations on suppliers, vendors or other entities that provide products or services to registered
entities. While proposed Reliability Standard CIP-013-1 requires applicable registered entities to
implement a supply chain risk management plan when they engage with third-party providers of
products and services for BES Cyber Systems, it does not directly create any obligations for
suppliers, vendors or other entities. The focus is on the steps registered entities take to account for
40
Id. at P 21.
14
security issues during the planning and procurement phase of high and medium impact BES Cyber
Systems. Any resulting obligation that a supplier, vendor or other entity accepts in providing
products or services to the registered entity is a contractual matter between the registered entity
and the third party outside the scope of the proposed Reliability Standard, as discussed further
below. Similarly, the modifications in CIP-005-6 and CIP-010-3 apply solely to registered entities.
The applicability section of the proposed Reliability Standards are the same as those in
each of the existing CIP cybersecurity Reliability Standards. The list of functional entities subject
to the proposed Reliability Standards is thus the same as those functional entities subject to each
of the existing CIP cybersecurity Reliability Standards, CIP-002-5.1a through CIP-011-2. 41 These
functional entities include: Balancing Authorities, certain Distribution Providers, Generator
Operators, Generator Owners, Reliability Coordinators, Transmission Operators, and
Transmission Owners. The standard drafting team (“SDT”) for Project 2016-03 concluded that the
same functional entities subject to the existing CIP cybersecurity Reliability Standards should also
be subject to the proposed supply chain cybersecurity risk management requirements as they are
intended to accomplish the same purpose: to mitigate the risk of a cybersecurity incident affecting
the reliable operation of the BES.
Similarly, the list of Facilities subject to the proposed Reliability Standards is the same as
those Facilities included in the existing CIP cybersecurity Reliability Standards. That is, for
functional entities other than Distribution Providers, all BES Facilities, systems, and equipment
are in scope, unless subject to an exemption listed in Applicability Section 4.2.3. The phrase “BES
Facilities, systems, and equipment” refers to the assets that make up or are used to operate the
41
The only exception is that proposed Reliability Standard CIP-013-1 does not include Interchange
Coordinator or Interchange Authority as applicability entities. These functional entities are no longer registered with
NERC and subject to NERC Reliability Standards.
15
BES, such as Transmission stations/substations, generation resources, Protection Systems, and
Control Centers. For Distribution Providers, there is a more limited set of Facilities, systems, and
equipment subject to the proposed Standards, as provided in Applicability Section 4.2.1. As with
the list of functional entities, given that the overall purpose of the proposed Reliability Standards
is consistent with the purpose of the existing CIP cybersecurity Reliability Standards, the initial
scoping of the Facilities subject to the proposed Reliability Standards should be consistent with
the applicability of the existing CIP cybersecurity Reliability Standards.
2) Applicable BES Cyber Systems
As with existing Reliability Standards CIP-004-6 through CIP-011-2, the requirements in
the proposed Reliability Standards apply only to BES Cyber Systems designated as medium or
high impact pursuant to Reliability Standard CIP-002-5.1a. The currently-effective CIP Reliability
Standards apply a risk-based construct, requiring Responsible Entities to identify and categorize
BES Cyber Systems as high, medium, or low impact, and then protect those BES Cyber Systems
commensurate with the risks they present to the reliable operation of the BES. 42 High and medium
impact BES Cyber Systems are associated with those BES Facilities, systems, and equipment that
are most critical to interconnected operations. In turn, the CIP Reliability Standards require
additional protections for these BES Cyber Systems as compared to those applicable to low impact
BES Cyber Systems. The goal of the CIP Reliability Standards is to provide for comprehensive
coverage of Cyber Assets that could impact Real-time operations while focusing industry
resources on protecting those BES Cyber Systems with heightened risks to the BES. To that end,
the Commission recognized in Order No. 791 that the requirements applicable to low impact BES

16
Cyber Systems, given their lower risk profile, should not be overly burdensome to divert resources
from the protection of medium and high impact BES Cyber Systems. 43
Reliability Standards CIP-004-6 through CIP-011-3 contain detailed requirements
applicable to the protection of high and medium impact, covering the following topics: personnel
and training (CIP-004-6); 44 electronic security perimeters and remote access protections (CIP-0055); 45 physical security (CIP-006-6); 46 systems security management (CIP-007-6); 47 incident
reporting and response planning (CIP-008-5); 48 recovery plans (CIP-009-6); 49 configuration
change management (CIP-010-2); 50 and BES Cyber System Information protection (CIP-011-2).51
In contrast, Reliability Standard CIP-003-6 contains all the requirements applicable to low impact
BES Cyber Systems, covering the following four subject matter areas: (1) cyber security
awareness; (2) physical security controls; (3) electronic access controls; and (4) Cyber Security
43
Id. at P 111 (finding that it would be unduly burdensome to require responsible entities to create and
maintain an inventory of Low Impact assets for audit purposes).
44
CIP-004-6 requires Responsible Entities to implement a cyber security awareness program, implement a
cyber security training program, conduct background checks for authorizing electronic and unescorted physical
access, implement an access management program for authorizing electronic and unescorted physical access, and
implement an access revocation program.
45
CIP-005-5 requires Responsible Entities to manage electronic access by: (1) logically protecting and
segmenting BES Cyber Systems and associated Protected Cyber Assets through use of Electronic Security
Perimeters; and (2) implementing remote access protection.
46
CIP-006-6 requires Responsible Entities to: (1) set up a Physical Security Perimeter (“PSP”), restrict access
into the PSP, and monitor for unauthorized access and issue alerts; and (2) establish a visitor control program
(escorted access, logging).
47
CIP-007-6 requires Responsible Entities to implement controls related to ports and services, security patch
management, malicious code prevention, security event monitoring, and system access control.
48
CIP-008-5 requires Responsible Entities to: (1) implement a cyber security incident response plan that sets
forth process for identifying, classifying and responding to Cyber Security Incidents and for reporting incidents that
compromise or disrupt a reliability task to E-ISAC; and (2) periodically test and update the response plan.
49
CIP-009-6 requires Responsible Entities to: (1) implement a recovery plan to address the recovery of
reliability functions performed by BES Cyber Systems; and (2) periodically test and update the response plan.
50
CIP-010-2 requires Responsible Entities to: (1) establish a configuration change management plan to
prevent and detect unauthorized changes to BES Cyber Systems; (2) conduct periodic vulnerability assessments; and
(3) implement controls for use transient electronic devices to prevent the spread of malicious code.
51
CIP-011-2 requires Responsible Entities to implement controls to protection BES Cyber Security
Information.
17
Incident response. Proposed Reliability Standard CIP-003-7, which is pending before the
Commission in Docket No. RM17-11-000, would add a fifth subject matter – protection of
transient electronic devices – applicable to low impact BES Cyber Systems. 52
The SDT chose to rely on the existing risk-based framework in the CIP Reliability
Standards and applied the requirements in the proposed Reliability Standards only to high and
medium impact BES Cyber Systems as they are consistent with the type of existing CIP
cybersecurity requirements applicable to high and medium impact BES Cyber Systems as opposed
to those applicable to low impact BES Cyber Systems. Prioritizing high and medium impact BES
Cyber Systems in the new supply chain risk management requirements appropriately focuses
industry resources on protecting the most impactful BES Cyber Systems. The proposed Reliability
Standards prioritize high and medium impact BES cyber systems by specifying mandatory
requirements applicable to such systems, while affording entities the flexibility to determine
appropriate supply chain cybersecurity risk management steps for low impact BES Cyber Systems.
The approach provides an opportunity for industry to address complex supply chain cybersecurity
risks in a measured manner, using an established prioritization mechanism. The benefit of this
approach is that it allows entities to initially focus their resources on the higher impact BES Cyber
Systems, which may eventually lead to better supply chain cybersecurity risk management plans
throughout the organization.
NERC anticipates, however, that Responsible Entities with high or medium impact BES
Cyber Systems may also apply their supply chain cybersecurity risk management plans to low
52
In short, for low impact BES Cyber Systems, CIP-003-7 would require entities to: (1) reinforce cyber
security practices once every 15 months; (2) control physical access to low impact BES Cyber Systems; (3) permit
only necessary inbound and outbound electronic access (or authenticate Dial-up Connectivity) to the low impact
BES Cyber; (4) have a Cyber Security Incident response plan; and (5) apply protections to transient electronic
devices connected to BES Cyber Systems.
18
impact BES Cyber Systems. During development of the proposed Reliability Standard, entities
commented that many of the same vendors supply products and services for all three impact
categories and that the same products and services are procured for all three impact categories
without differentiation. As such, by requiring that entities implement supply chain cybersecurity
risk management plans for high and medium impact BES Cyber Systems, those plans would likely
also cover their low impact BES Cyber Systems. Entities may decide not to establish two separate
processes for the procurement of products and services for BES Cyber Systems based on impact
level, either because during the planning and procurement phase they may not know which
environment that system will be placed or simply because it is organizationally more efficient to
have a single process for planning and procuring all BES Cyber Systems. Additionally, as
Responsible Entities implement their supply chain cybersecurity risk management plans, the
vendor community serving the electric industry may respond by including certain security
concepts in product design and as standard provisions in future contracts for BES Cyber Systems,
regardless of impact level. In this manner, implementation of proposed Reliability Standard CIP013-1 could enhance the security for all BES Cyber Systems, not just those to which the Reliability
Standard specifically applies.
The SDT also excluded Physical Access Controls (“PACS”), Electronic Access Control
and Monitoring Systems (“EACMS”), and Protected Cyber Assets (“PCAs”) from the scope of the
proposed Reliability Standards, with the exception of the modifications in proposed Reliability
Standard CIP-005-6, which also apply to PCAs. While certain of the requirements in the existing
CIP Reliability Standards require Responsible Entities to apply certain protections to PACS,
EACMS, and PCAs, given their association with BES Cyber Systems (either by function or
location), the SDT determined that for purposes of proposed Reliability Standard CIP-013-1 and
19
the modifications in proposed Reliability Standard CIP-010-3, the requirements should focus on
high and medium impact BES Cyber Systems only. High and medium impact BES Cyber Systems
directly impact Real-time operations and, in turn, present the greatest level of risk to reliable
operations. As with the exclusion of low impact BES Cyber Systems, the SDT concluded that
applying the proposed supply chain risk management requirements to PACS, EACMS, and PCAs
would divert resources from protecting medium and high BES Cyber Systems.
Nevertheless, NERC expects that many of these Cyber Assets would be subject to the
supply chain risk management plans required by proposed Reliability Standard CIP-013-1.
Registered Entities may implement a single process for procuring products and service associated
with their operational environments. Further, registered entities may also use the same vendors for
procuring PACS, EACMS, and PCAs as they do for high and medium impact BES Cyber Systems
such that the same security considerations may be addressed for those Cyber Assets.
NERC will continue studying supply chain risks to determine whether the proposed
Reliability Standards are appropriately scoped to mitigate those risks. In the series of resolutions
the NERC Board issued when adopting the proposed Reliability Standards, the Board requested
that:
(i) NERC management, in collaboration with the appropriate NERC technical
committees, industry representatives and appropriate experts, including
representatives of industry vendors, further study the nature and complexity of
cyber security supply chain risks, including risks associated with low impact assets
not currently subject to the Supply Chain Standards, and develop recommendations
for follow-up actions that will best address any issues identified, and (ii) NERC
management provide an interim report to the Board related to the foregoing by no
later than approximately 12 months after the adoption of these resolutions and a
follow-up final report to the Board no later than approximately 18 months after the
adoption of these resolutions.
20
Accordingly, over the next 18 months, NERC, working with various stakeholders, will continue
to assess whether supply chain risks related to low impact BES Cyber Systems, PACS, EACMS,
and PCA necessitate further consideration for inclusion in a mandatory Reliability Standard.
3) Applicable Third-Party (Vendor) Products and Services
Proposed Reliability Standard CIP-013-1 and the proposed modifications in Reliability
Standard CIP-005-6, Requirement R2 apply to interactions with “vendors.” As used in these
proposed Reliability Standards, the term “vendor” is used broadly to refer to any person, company,
or other organization with whom the Responsible Entity, or an affiliate, contracts with to supply
BES Cyber Systems and related services to the Responsible Entity. A vendor, as used in the
standard, may thus include: (i) developers or manufacturers of information systems, system
components, or information system services; (ii) product resellers; or (iii) system integrators. The
use of the term “vendor,” however, was not intended to bring within the scope of these proposed
Reliability Standards registered entities that provide reliability services to other registered entities
as part of their functional obligations under NERC’s Reliability Standards (e.g., a Balancing
Authority providing balancing services for registered entities in its Balancing Authority Area).
4) Applicable Vendor Contracts
Implementation of the requirements in the proposed Reliability Standards do not require
Responsible Entity’s to renegotiate or abrogate existing contracts with vendors executed as of the
effective date of the proposed Reliability Standards. As noted above, in Order No. 829, the
Commission directed NERC to develop a “forward-looking” Reliability Standard. As the
Commission explained in its Notice of Proposed Rulemaking leading to Order No. 829, a
“forward-looking” Reliability Standard is one that does not dictate the abrogation or re-negotiation
21
of currently-effective contracts with vendors. 53 As such, the requirements to develop and
implement supply chain risk management plans according to CIP-013-1 apply only to new
arrangements with vendors for BES Cyber Systems. 54 Responsible Entities need not apply their
supply chain risk management plans to the acquisition of applicable vendor products or services
pursuant to contracts executed prior to the effective date of CIP-013-1 nor would such contracts
need to be renegotiated or abrogated to comply with the proposed Reliability Standard.
Additionally, and consistent with the development of a “forward looking” Reliability Standard, if
entities are in the middle of procurement activities for an applicable product or service at the time
of the effective date of proposed Reliability Standard CIP-013-1, NERC would not expect entities
to begin those activities anew to implement their supply chain cybersecurity risk management plan
to comply with proposed Reliability Standard CIP-013-1.
Similarly, Responsible Entities may implement the new requirements in proposed CIP005-6 and CIP-010-1 without renegotiating or abrogating existing contracts. Nothing in those
requirements require that entities renegotiate or abrogate existing contracts. 55
C.
Proposed Requirements of Proposed Reliability Standard CIP-013-1
The focus of proposed Reliability Standard CIP-013-1, and the development and
implementation of supply chain cybersecurity risk management plans in particular, is on the steps
Responsible Entities take to consider and address cyber security risks from vendor products or
services during BES Cyber System planning and procurement. Given the (i) differences in the
53
Revised Critical Infrastructure Protection Reliability Standards, 152 FERC ¶ 61,054, at P 64 (2015).
54
Requirement R2 of proposed Reliability Standard CIP-013-1 specifically includes a note that
implementation does not require the Responsible Entity to renegotiate or abrogate existing contracts (including
amendments to master agreements and purchase orders).
55
New Part 1.6 of proposed Reliability Standard CIP-010-3 specifically includes a note that implementation
does not require the Responsible Entity to renegotiate or abrogate existing contracts (including amendments to
master agreements and purchase orders).
22
needs and characteristics of registered entities and (ii) diversity of BES environments,
technologies, and risks, proposed Reliability Standard CIP-013-1 does not impose any specific
controls nor mandate “one-size-fits-all” requirements, consistent with Order No. 829. 56 The goal
is to help ensure that Responsible Entities establish organizationally-defined processes that
integrate a cybersecurity risk management framework into the system development life cycle.
Proposed Reliability Standard CIP-013-1 includes the following three requirements, each
of which is discussed below:
R1.
Each Responsible Entity shall develop one or more documented supply
chain cyber security risk management plan(s) for high and medium impact
BES Cyber Systems. The plan(s) shall include: [Violation Risk Factor:
Medium] [Time Horizon: Operations Planning]
1.1.
One or more process(es) used in planning for the procurement of
BES Cyber Systems to identify and assess cyber security risk(s) to
the Bulk Electric System from vendor products or services resulting
from: (i) procuring and installing vendor equipment and software;
and (ii) transitions from one vendor(s) to another vendor(s).
1.2.
One or more process(es) used in procuring BES Cyber Systems that
address the following, as applicable:
1.2.1. Notification by the vendor of vendor-identified incidents
related to the products or services provided to the
Responsible Entity that pose cyber security risk to the
Responsible Entity;
1.2.2. Coordination of responses to vendor-identified incidents
related to the products or services provided to the
Responsible Entity that pose cyber security risk to the
Responsible Entity;
1.2.3. Notification by vendors when remote or onsite access should
no longer be granted to vendor representatives;
1.2.4. Disclosure by vendors of known vulnerabilities related to the
products or services provided to the Responsible Entity;
56
Order No. 829 at P 2.
23
1.2.5. Verification of software integrity and authenticity of all
software and patches provided by the vendor for use in the
BES Cyber System; and
1.2.6. Coordination of controls for (i) vendor-initiated Interactive
Remote Access, and (ii) system-to-system remote access
with a vendor(s).
R2.
Each Responsible Entity shall implement its supply chain cyber security
risk management plan(s) specified in Requirement R1.
R3.
Each Responsible Entity shall review and obtain CIP Senior Manager or
delegate approval of its supply chain cyber security risk management
plan(s) specified in Requirement R1 at least once every 15 calendar months.
Requirement R1 mandates that each Responsible Entity develop a supply chain
cybersecurity risk management plan for high and medium impact BES Cyber Systems. These plans
are designed to ensure that Responsible Entities: (1) adequately consider security risks when
planning for high and medium impact BES Cyber Systems (Part 1.1); and (2) take steps to address
relevant security concepts in future contracts for high and medium impact BES Cyber Systems
(Part 1.2).
Specifically, pursuant to Part 1.1, Responsible Entities must have a process to identify and
assess cybersecurity risks to the BES from vendor products and services, related to both the
procurement and installation of vendor products as well as transitioning between vendors. This
obligation addresses the third objective outlined in Order No. 829 to address a Responsible Entity’s
“identification and documentation of the risks of proposed information system planning and
system development actions.” 57 As the Commission stated in Order No. 829, this “objective
addresses “the risk that [R]esponsible [E]ntities could unintentionally plan to procure and install
unsecure equipment or software within their information systems, or could unintentionally fail to
57
Id. at P 56.
24
anticipate security issues that may arise due to their network architecture or during technology and
vendor transitions.”
Requiring entities to identify and assess cybersecurity risks during the planning phase of
the system life cycle helps ensure that Responsible Entities make informed decisions by adequately
considering the cybersecurity risks presented by a particular vendor, product, or service, as well
as available options for mitigating any such risks. Based on the identification and assessment of
risks, the Responsible Entity may choose not to move forward with a particular vendor or product
or, if it chooses to move forward, implement targeted mitigation measures to harden its BES Cyber
System, minimize the attack surface, ensure ongoing support for system components, and identify
alternate sources for critical components, among other things.
Pursuant to Part 1.2, Responsible Entities must also have processes to address the following
baseline set of security concepts in their procurement activities for high and medium impact BES
Cyber Systems: (1) vendor security event notification processes (Part 1.2.1); (2) coordinated
incident response activities (Part 1.2.2); (3) vendor personnel termination notification for
employees with access to remote and onsite systems (Part 1.2.3); (4) product/services vulnerability
disclosures (Part 1.2.4); (5) verification of software integrity and authenticity (Part 1.2.5); and (5)
coordination of vendor remote access controls (Part 1.2.6). Part 1.2 addresses the fourth objective
outlined in Order No. 829 to “address the provision and verification of relevant security concepts
in future contracts for industrial control system hardware, software, and computing and networking
services associated with bulk electric system operations.” 58
58
Id. at P 59.
25
Each item listed in Parts 1.2.1 through 1.2.4 corresponds to a topic specifically listed in
Order No. 829 for which entities must have controls. 59 Further, Parts 1.2.5 and 1.2.6 address,
together with the modifications in proposed Reliability Standards CIP-005-6 and CIP-010-3, the
first and second objective discussed in Order No. 829 related to software integrity and authenticity
and vendor remote access. Collectively, each of the listed items help address the risks that: (1)
Responsible Entities could enter into contracts with vendors who pose significant risks to their
information systems; (2) products procured by a Responsible Entity fail to meet minimum security
criteria; and (3) a compromised vendor would not provide adequate notice of security issues and
related incident response to Responsible Entities with whom that vendor is connected. 60 As
discussed further below, the focus of Part 1.2 is not on requiring that every contract with a vendor
includes provisions for each of the listed items but on developing processes to ensure that these
security items are an integrated part of procurement activities (e.g., these topics are included in
requests for proposals (“RFPs”) or the contract negotiation process).
Requirement R2 mandates that each Responsible Entity implement its supply chain
cybersecurity risk management plan developed in accordance with Requirement R1. Requirement
R2 also includes the following note:
Implementation of the plan does not require the Responsible Entity to renegotiate
or abrogate existing contracts (including amendments to master agreements and
purchase orders). Additionally, the following issues are beyond the scope of
Requirement R2: (1) the actual terms and conditions of a procurement contract; and
(2) vendor performance and adherence to a contract.
As discussed above, the note that implementation of the supply chain cybersecurity risk
management plans do not require the renegotiation or abrogation of existing contracts is consistent
59
Id. at P 59.
60
Id. at P 61.
26
with the Commission’s statement in Order No. 829 to develop a “forward-looking” Reliability
Standard.
Similarly, the note that (1) the actual terms and conditions of a procurement contract; and
(2) vendor performance and adherence to a contract are outside the scope of proposed Reliability
Standards CIP-013-1 is consistent with the directive in Order No. 829 to develop an objectivebased supply chain cybersecurity risk management Reliability Standard that “account[s] for,
among other things, differences in the needs and characteristics of [R]esponsible [E]ntities and the
diversity of BES Cyber System environments, technologies and risks.” 61 As noted above, the focus
of CIP-013-1 is on the processes Responsible Entities implement to consider and address cyber
security risks from vendor products or services during BES Cyber System planning and
procurement, not on the outcome of those processes, such as the Responsible Entity choice of
vendor for a particular product or service, the negotiated contract terms for a particular product
service, or the vendor’s adherence performance under the contract to implement the various
security provisions agreed to by the parties). Those outcomes are more appropriately left to the
discretion of the Responsible Entity.
Proposed Reliability Standard CIP-013-1 must be flexible enough to account for the
significant differences in the purchasing power and resource needs of various Responsible Entities
and balance the reliability need to implement supply chain management security controls with a
Responsible Entities’ business need to obtain products and services at a reasonable cost. A
Responsible Entity may not have the ability to obtain each of its desired cybersecurity controls in
its contract with each of its vendors. Factors such as competition, limited supply sources, expense,
criticality of the product or service, and maturity of the vendor or product line could affect the
61
Id. at P 44.
27
terms and conditions ultimately negotiated by the parties and included in a contract. After weighing
the risks associated with a vendor or product and making a good faith effort to include security
controls in any agreement with a vendor, as required by proposed CIP-013-1, Responsible Entities
must make a business decision on whether and how to proceed. Variation in contract terms is thus
anticipated and, in turn, the note in Requirement R2 provides that the actual terms and conditions
of the contract are outside the scope of Reliability Standard CIP-013-1.
Similarly, a vendor’s performance under its contract with a Responsible Entity should
remain outside the scope of the proposed Reliability Standard. While NERC expects Responsible
Entities to enforce the security provisions in its vendor contracts, a Responsible Entity should not
be held responsible under the proposed Reliability Standard for actions (or inactions) of the vendor.
The aim of the proposed Reliability Standard is to create an affirmative obligation for Responsible
Entities to implement supply chain cybersecurity risk management controls without holding them
strictly liable for the actions of its vendors. There are many factors (e.g., risk assessment,
relationship with counterparty, cost, etc.) that go into a decision to enforce contract provisions
against the counterparty. Such decisions are not susceptible to a one-size-fits-all mandate in a
mandatory Reliability Standard. As such, the note in Requirement R2 provides that vendor
performance and adherence to a contract are outside the scope of proposed Reliability Standard
CIP-013-1.
Accordingly, failure to obtain a specific contract provision for an item listed in Part 1.2, or
the failure to enforce a security provision in a vendor contract would not constitute a violation of
Requirements R1 or R2 of proposed Reliability Standard CIP-013-1. In assessing compliance with
the proposed Reliability Standard, the ERO would focus on whether the Responsible Entity: (1)
developed processes reasonably designed to (i) identify and assess risks associated with vendor
28
products and services in accordance with Part 1.1, and (ii) ensure that the security items listed in
Part 1.2 are an integrated part of procurement activities; and (2) implemented those processes in
good faith. On the latter element, the ERO will evaluate the steps Responsible Entity’s took, in
accordance with its supply chain cybersecurity risk management plan, to assess risks posed by a
vendor and associated products or services and, based on that risk assessment, the steps the entity
took to mitigate those risk, including the negotiation of security provisions in its agreements with
the vendor.
Consistent with the Commission statement that “the Reliability Standard should set goals
(the “what”), while allowing flexibility in how a responsible entity subject to the Reliability
Standard achieves that goal (the “how”),” Requirements R1 and R2 of proposed CIP-013-1
provides Responsible Entities flexibility to develop and implement processes that best suits the
needs and characteristics of their organization, and the BES system environments to which a
vendor product or service relates. To assist with the implementation of proposed Reliability
Standard CIP-013-1, the SDT developed an Implementation Guidance document, endorsed by the
ERO consistent with its Compliance Guidance Policy, 62 which outlines various approaches to
implementing proposed Reliability Standard CIP-013-1. That Implementation Guidance provides,
among other things, that in developing and implementing its supply chain cybersecurity risk
management plan, a Responsible Entity may consider using a risk-based approach that identifies
and prioritizes security controls based on the cybersecurity risks presented by the vendor and the
criticality of the product or service to reliable operations. For instance, Responsible Entities may
establish a baseline set of controls for given products or services that a vendor must meet prior to
62
The SDT’s Implementation Guidance is provided in Exhibit E hereto. The ERO’s Compliance Guidance
Policy is available at
http://www.nerc.com/pa/comp/Resources/ResourcesDL/Compliance_Guidance_Policy_FINAL_Board_Accepted_N
ov_5_2015.pdf.
29
transacting with that vendor for those products and services (i.e., “must-have controls”). As risks
differ between products and services, the baseline security controls – or “must haves” – may differ
for the various products and services that the Responsible Entity procures for its BES Cyber
Systems. This risk-based approach could help create efficiencies in the Responsible Entity’s
procurement processes while meeting the security objectives of Requirement R1.
Additionally, for Requirement R1, the Implementation Guidance outlines two basic
approaches for developing supply chain cybersecurity risk management plans:
One element of, or approach to, a risk-based cyber security risk management plan
is system-based, focusing on specific controls for high and medium impact BES
Cyber Systems to address the risks presented in procuring those systems or services
for those systems. A risk-based approach could also be vendor-based, focusing on
the risks posed by various vendors of its BES Cyber Systems. Entities may combine
both of these approaches into their plans.
The Implementation Guidance provides additional detailed considerations for implementing the
requirements in proposed Reliability Standard CIP-013-1 and examples of approaches that
Responsible Entities could use to meet the requirements.
Requirement R3 of proposed Reliability Standard CIP-013-1 addresses the Order No. 829
directives to require each Responsible Entity to periodically reassess its supply chain cyber
security risk management controls. 63 Under Requirement R3, the Responsible Entity shall review
and obtain its CIP Senior Manager’s (or delegate’s) approval of its supply chain risk management
plan at least once every 15 calendar months. This 15-month assessment helps ensure that the supply
chain cybersecurity risk management plan remains up-to-date, addressing current and emerging
supply chain-related concerns and vulnerabilities.

Order No. 829 at P 46.

D.
Proposed Modifications in Reliability Standard CIP-005-6
Proposed Reliability Standard CIP-005-6 includes two new parts in Requirement R2 – Part
2.4 and 2.5 – to address the second objective discussed in Order No. 829 regarding vendor remote
access sessions. 64 Parts 2.4 and 2.5 apply to medium and high impact BES Cyber Systems and
their associated PCAs and provide as follows:
2.4
Have one or more methods for determining active vendor remote access
sessions (including Interactive Remote Access and system‐to‐system
remote access).
2.5
Have one or more method(s) to disable active vendor remote access
(including Interactive Remote Access and system‐to‐system remote access).
These new requirement parts work in tandem with Requirement R1 Part 1.2.6 of proposed
Reliability Standard CIP-013-1 to address vendor remote access. As discussed above, Requirement
R1 Part 1.2.6 of proposed CIP-013-1 creates an affirmative obligation during procurement
activities for Responsible Entities to address the coordination of controls with the vendor for
Interactive Remote Access and system-to-system remote access. Parts 2.4 and 2.5 of proposed
CIP-005-6 complement that obligation by creating affirmative obligations in the operational phase
for Responsible Entities to have one or more methods for: (1) determining active vendor remote
access sessions (Part 2.4); and (2) disabling active vendor remote access (Part 2.5). The security
objective of these requirement parts is to control vendor remote access to mitigate risks associated
with unauthorized access (i.e., reduce the probability that an attacker could use legitimate thirdparty access to compromise Responsible Entity systems).
More specifically, the objective of Part 2.4 is for entities to have visibility into all active
vendor remote access sessions (both Interactive Remote Access and system‐to‐system remote
access) that are taking place on their system. The objective of Requirement R2 Part 2.5 is for
64
Id. at P 51.
31
entities to have the ability to disable active remote access sessions in the event of a system breach.
Visibility into vendor remote access sessions and the capability to rapidly disable such sessions
will help prevent unauthorized access and the type of cyberattack that successfully affected the
Ukraine’s power grid in 2015. 65
In addition to adding Parts 2.4 and 2.5 to the Reliability Standard, NERC modified
Requirement R2 to only reference Interactive Remote Access where appropriate. With the
exception of proposed Parts 2.4 and 2.5, Requirement R2 applies only to Interactive Remote
Access, not system-to-system remote access. Accordingly, the phrase “allowing Interactive
Remote Access to BES Cyber Systems” was removed from the introductory sentence of
Requirement R2 but the phrase “For all Interactive Remote Access,” was included in Part 2.1.
NERC also made other clean-up changes in the proposed CIP-005-6 Reliability Standard,
including changes to the standard so as to be consistent with NERC’s newer template, and deleting
from the Applicability Section of the standard references to Special Protection System (“SPS”),
which is now defined to refer to the Remedial Action Scheme (“RAS”) definition. 66 The
Applicability Section of the proposed Reliability Standard now references RAS only.
E.
Proposed Modifications in Reliability Standard CIP-010-3
Proposed Reliability Standard CIP-010-6 includes a new part in Requirement R1 – Part 1.6
– to address the first objective discussed in Order No. 829 regarding verification of: (1) the identity
of the software publisher for all software and patches that are intended for use on BES Cyber
Systems; and (2) the integrity of the software and patches before they are installed in the BES

Cyber System environment. 67 Consistent with that objective, Requirement R1 Part 1.6 of proposed
Reliability Standard CIP-010-3 provides:
1.6
Prior to a change that deviates from the existing baseline configuration
associated with baseline items in Parts 1.1.1, 1.1.2, and 1.1.5, and when the
method to do so is available to the Responsible Entity from the software
source:
1.6.1. Verify the identity of the software source; and
1.6.2. Verify the integrity of the software obtained from the software source.
Essentially, Part 1.6 provides that prior to installing software that changes the established
baseline configuration for (1) operating system(s) (including version) or firmware where no
independent operating system exists (Part 1.1.1), (2) any commercially available or open-source
application software (including version) intentionally installed (Part 1.1.2), or (3) any custom
software installed (Part 1.1.3), Responsible Entities must verify the identity of the software source
and the integrity of the software obtained by the software sources, when methods are available to
do so. The security objective of verifying software integrity and authenticity is to ensure that the
software being installed in the BES Cyber System was not modified without the awareness of the
software supplier and is not counterfeit. These steps, as the Commission stated in Order No. 829,
help “reduce the likelihood that an attacker could exploit legitimate vendor patch management
processes to deliver compromised software updates or patches to a BES Cyber System.” 68
As with Parts 2.4 and 2.5 of proposed CIP-005-6, proposed Part 1.6 works in tandem with
Requirement R1 Part 1.2.5 of proposed CIP-013-1 to address software integrity and authenticity.
As discussed above, Requirement R1 Part 1.2.5 of proposed CIP-013-1 creates an affirmative
obligation during procurement activities for Responsible Entities to address the verification of

33
software integrity and authenticity for all software and patches provided by the vendor for use in
a BES Cyber System. Part 1.6 of proposed CIP-010-3 complements that obligation by creating an
affirmative obligation in the operational phase for Responsible Entities to verify software integrity
and authenticity. The obligation to verify software integrity and authenticity, however, can only
be accomplished if the source of the software provides a method to do so. Hence, it is important
for entities to address this matter in their procurement activities, as required by CIP-013-1.
In addition to adding Part 1.6 to the Reliability Standard, NERC also made other clean-up
changes, including changes to the standard so as to be consistent with NERC’s newer template,
and deleting from the Applicability Section of the standard references to SPS, which is now defined
to refer to the RAS definition as noted above. The Applicability Section of the proposed Reliability
Standard now references RAS only.
F.
Enforceability of Proposed Reliability Standards
The proposed Reliability Standards also include measures that support each requirement
by clearly identifying what is required and how the ERO will enforce the requirement. These
measures help ensure that the requirements will be enforced in a clear, consistent, and nonpreferential manner and without prejudice to any party. 69 Additionally, the proposed Reliability
Standards include VRFs and VSLs. The VRFs and VSLs provide guidance on the way that NERC
will enforce the requirements of the proposed Reliability Standards. The VRFs and VSLs for the
proposed Reliability Standards comport with NERC and Commission guidelines related to their
assignment. Exhibit F provides a detailed review of the VRFs and VSLs, and the analysis of how
the VRFs and VSLs were determined using these guidelines.

V.
EFFECTIVE DATE
NERC respectfully requests that the Commission approve the proposed Reliability
Standards to become effective as set forth in the proposed Implementation Plan, provided in
Exhibit B hereto. The proposed Implementation Plan provides that the proposed Reliability
Standards shall become effective on the first day of the first calendar quarter that is 18 calendar
months after the effective date of the Commission’s order approving the proposed Reliability
Standard. The 18-month implementation period is designed to afford Responsible Entities
sufficient time to develop and implement their supply chain cybersecurity risk management plans
according to proposed Reliability Standard CIP-013-1 and implement the new controls required in
proposed Reliability Standards CIP-005-6 and CIP-010-3.
VI.
ACTIVITIES TO SUPPORT IMPLEMENTION OF THE PROPOSED
RELIABILITY STANDARDS AND ADDRESS RESIDUAL RISKS
In addition to directing NERC management to further study the nature and complexity of
cyber security supply chain risks, as discussed above, as part of the resolutions it issued when
adopting the proposed Reliability Standards, the Board directed NERC management to take a
number of steps to support successful implementation of the proposed Reliability Standards.
Specifically, the Board directed NERC management to do the following:
•
“[C]ommence appropriate preparations for implementation of the Supply Chain standards
utilizing methods similar to those utilized for the implementation of the CIP v 5 reliability
standards as deemed appropriate by NERC management, and regularly report to the Board
on such activities.”
•
“[U]tilizing information it is authorized to use and other information collected through
interactions with industry and governmental authorities, communicate supply chain risk
developments and risks to industry and in connection with the efforts contemplated by the
foregoing resolutions.”
The Board also requested that certain stakeholder groups take certain actions to support
implementation activities. Specifically, the Board requested the following:
35
•
“[T]hat each of the North American Transmission Forum and the North American
Generation Forum (the “Forums”) develop white papers to address best and leading
practices in supply chain management, including procurement, specifications, vendor
requirements and existing equipment management, that are shared across the membership
of each Forum, and to the extent permissible under any applicable confidentiality
requirements, distribute such white papers to industry.”
•
“[T]hat the Board hereby requests that each of the National Rural Electric Cooperative
Association and the American Public Power Association (the “Associations”) develop
white papers addressing issues contemplated by the immediately preceding resolution,
focusing on smaller entities that are not members of the Forums, for the membership of the
Associations, and to the extent permissible under any applicable confidentiality
requirements, distribute such white papers to industry.
The Board also requested that “NERC management, collaborating with the appropriate
NERC technical committees and other experts as deemed appropriate by management, develop a
plan to evaluate the effectiveness of the Supply Chain Standards, including seeking input from
registered entities subject to the Supply Chain Standards, and report back to the Board as
appropriate.”
Consistent with the Board’s resolutions, NERC is planning a number of coordinated
activities to support (i) industry’s implementation of the proposed Reliability Standards and (ii)
broader efforts to address and mitigate supply chain cybersecurity risks. The purpose of these
activities is to accomplish the following objectives, among others: (1) enhancing industry’s
readiness to implement the Reliability Standards; (2) clarifying compliance and enforcement
expectations; (3) ensuring consistent and reasonable enforcement of the proposed Reliability
Standards; (4) assessing the effectiveness of the proposed Reliability Standards in mitigating
supply chain cybersecurity risks; (5) fostering increased analysis and information sharing of supply
chain cybersecurity threats and vulnerabilities and risk management best practices; and (6)
promoting programs within the electric industry designed to identify supply chain cybersecurity
threats and vulnerabilities and enhance supply chain risk management activities. NERC will
36
engage directly with registered entities, the vendor community, and relevant governmental entities,
among others, to accomplish these objectives.
In its plans to support implementation of the proposed Reliability Standards, NERC is
drawing on its past initiatives and lessons learned in support of the transition to other significant
sets of Reliability Standards, particularly the transition to the CIP Reliability Standards approved
in Order Nos. 791 and 822, 70 commonly referred to as the CIP version 5 Reliability Standards.
NERC’s early engagement in supporting transition to the CIP version 5 Reliability Standards
helped identify and address implementation issues to support an efficient and effective transition.
For the proposed Reliability Standards, NERC plans the following types of activities beginning in
the fourth quarter of 2017 and continuing into 2018 and beyond:
•
Implementation Study and Advisory Task Force – Drawing from lessons learned from the
transition to the CIP version 5 Reliability Standards, NERC plans to identify and solicit a
core group of volunteer registered entities with mature supply chain risk management
practices to participate in an implementation study and serve on an advisory task force to
provide feedback on Reliability Standard application successes and challenges, identify
needed enhanced Implementation Guidance, and share best practices. Specifically, NERC
plans to collaborate with select registered entities during their implementation of the
proposed Reliability Standards to better understand and assess the effectiveness of those
Supply Chain standards (and associated Implementation Guidance) at mitigating supply
chain cybersecurity risks. A central focus of this initiative will be to measure the impact
and influence that the proposed Reliability Standards have in shaping supply chain
cybersecurity risk management behaviors and practices across the electric industry. This
initiative will also evaluate the manner in which vendors have responded to registered
entities’ implementation of the proposed Reliability Standards.
•
Auditor Training – To help ensure consistent application of the proposed Reliability
Standards, NERC will focus on Regional Entity auditor training on the concepts in the
proposed Reliability Standards along with application of associated Implementation
Guidance, focusing on acceptable approaches to compliance. Auditor training would be
informed by the lessons learned from the implementation study and the advisory task force.
•
Outreach and Communication – NERC plans to increase outreach and communication with
industry stakeholders to help ensure implementation readiness, including periodic
70
Version 5 Critical Infrastructure Protection Reliability Standards, Order No. 791, 145 FERC ¶ 61,160
(2013), order on clarification and reh’g, Order No. 791-A, 146 FERC ¶ 61,188 (2014); Revised Critical
Infrastructure Protection Reliability Standards, Order No. 822, 154 FERC ¶ 61,037 (2016).
37
webinars, small registered entity outreach, and other activities to align industry and
Regional Entity understanding on compliance approaches.
•
CIPC Guidance – NERC plans to engage the Critical Infrastructure Protection Committee
(“CIPC”) and other qualified groups to develop additional Implementation Guidance, as
needed.
•
Monitoring and Oversight – During implementation of the proposed Reliability Standards,
NERC will continue to develop oversight strategies to monitor compliance and assess the
effectiveness of the proposed Reliability Standards in helping to mitigate supply chain
cybersecurity risks to the BES.
•
Vendor Engagement – NERC plans to engage with the vendor community with a focus on
supply chain risk management controls.
Collectively, NERC expects that these types of initiatives will help: the identification and
sharing of supply chain cybersecurity risk management best practices to enhance industry’s
implementation readiness; validate existing guidance related to the proposed Reliability Standards;
identify areas that may need additional or enhanced guidance; promote increased awareness among
vendors of industry’s needs in meeting the proposed Reliability Standards; measure the impact of
the proposed Reliability Standards on supply chain cybersecurity risk management practices; and
evaluate whether the Supply Chain Standards adequately address identified or emerging supply
chain cybersecurity risks
Additionally, NERC is committed to using its many reliability tools – e.g., guidelines,
training exercises, alerts, information sharing and analysis – to further study and assess supply
chain cybersecurity risks and support the electric industry’s efforts to mitigate supply chain risks
outside of the context of compliance with the proposed Reliability Standards. Specifically, NERC
plans to initiate the following types of activities to promote actions that will address residual supply
chain cybersecurity risks:
•
NERC plans to work with CIPC and other technical committees to develop guidelines that
identify best practices, internal controls, as well as processes and concepts that can be
shared amongst registered entities to promote strong supply chain cybersecurity risk
management for all BES Cyber Systems. The guidelines would include legacy system
38
support for end-of-life products and the use of resellers or third-party suppliers for BES
Cyber System components.
•
NERC will explore opportunities to engage the vendor community through joint
industry/vendor working groups and targeted outreach (e.g. EMS vendor user groups) to
identify and address emerging supply-chain risks, as well as discuss system development
activities and security vulnerability identification processes.
•
NERC plans to review supply chain standards and other similar guidance documents
prepared by other standards setting organizations to gain additional insight for best
practices. NERC will share lessons learned from inside and outside the industry with
registered entities.
•
NERC will consider integrating a supply chain vulnerability in the next GridEx exercise,
including a post mortem analysis of the response efforts from entities.
•
NERC will explore opportunities to engage trade organizations to educate industry about
effective strategies for enhancing the reliability and security of supply chains, in addition
to the Board’s request that the Forums and Associations develop white papers.
•
NERC, primarily through the Electricity Information Sharing and Analysis Center (“EISAC”), will explore opportunities to engage governmental entities such as the Department
of Homeland Security (“DHS”) and the Department of Energy (DOE) on an overarching
strategy for addressing supply chain risks.
•
NERC, primary through the E-ISAC, will continue to analyze and share information related
to supply chain threats and vulnerability and approaches to timely mitigate those threats
and vulnerabilities to help ensure the electric industry has situation awareness of and
remains focused on supply chain issues.
•
NERC will explore opportunities to engage the DOE National Laboratories and other
relevant organizations to encourage them to identify and share system vulnerability
information to the asset owner and vendor community. For example, NERC, in
coordination with the CIPC and other stakeholder groups, will explore opportunities to
work with the National Laboratories to test equipment and systems used by registered
entities in their operational environments to further assess whether cybersecurity
vulnerabilities exist in installed equipment or systems. The results of these tests would be
shared with applicable asset owners and vendors.
•
NERC will explore opportunities to engage the Institute of Electrical and Electronics
Engineers, Internet Engineering Task Force, International Electrotechnical Commission,
and other product manufacturing standards bodies to ensure that supply chain cybersecurity
risks and vulnerabilities are addressed in standard product specifications.
•
NERC will explore opportunities to assist stakeholders in developing an accreditation
model for identifying vendors with strong supply chain risk management practices. Such
identification would not only help entities comply with the proposed Reliability Standards
39
but also increase the level of confidence that vendors providing BES-related products and
services are effectively implementing supply chain cybersecurity controls and measures.
Through these or other similar activities, NERC, in coordination with its stakeholders,
intends to proactively address supply chain threats and vulnerabilities that could impact BES
reliability. The proposed Reliability Standards are one element of NERC’s efforts to increase focus
on supply chain-related cybersecurity risks and improve the cybersecurity practices in the electric
industry.
