Abstract
The Department of Homeland Security (DHS), Office of the Chief Security Officer (OCSO),
Physical Access Control Division (PHYSD) operates the Physical Access Control System (PACS).
PACS is a security technology integration application suite used to control and manage physical access
devices, intrusion detection, and video surveillance at DHS Headquarters (HQ) facilities in the National
Capital Region (NCR), primarily the Nebraska Avenue Complex (NAC). This PIA will focus exclusively
on the physical access control and intrusion detection functions within PACS. The video surveillance
function within PACS is covered by a separate PIA and can be found at www.dhs.gov/privacy. PACS
provides advanced access control, alarm monitoring, digital video,1 intrusion detection, and employee,
visitor, and parking management.
PACS allows authorized security personnel to simultaneously manage and monitor multiple entry
points from a single, centralized location. The OCSO has conducted this Privacy Impact Assessment
(PIA) to analyze the personally identifiable information (PII) that PACS collects, uses, and maintains. To
the extent that other Departmental components use a system(s) that operates in the same way as PACS
and will follow the rules outlined in this PIA, that system will be covered by this PIA and listed as part of
an update to this PIA appendix.

Overview
PACS operates access control and intrusion detection functions at DHS HQ facilities in the NCR,
primarily the NAC, and is comprised of a suite of applications which serve as a mechanism for the
management of electronic access points and alarms. PACS produces automated transactional reports,
documenting what activity took place, where and when.
PACS applications used at DHS HQ facilities in the NCR, primarily the NAC, are divided into
four areas: A) identification for access; B) visitor management; C) parking permit management; D) alarm
monitoring and intrusion detection. All four applications and processes operate independently at the
direction of the PACS Administrator.
A) Identification – PACS requires an individual’s PII so it can authorize physical access to DHS
facilities. PACS sensors read the information on an individual’s Personal Identity Verification (PIV) 2
card to verify if the individual is authorized access.
B) Visitor Management – Visitors and construction and service contractors 3 who have not been
issued a PIV card must be identified before being granted access. This is accomplished by having the
individual provide the information requested on DHS Form 11000-13 “Visitor Process Information.”
OCSO personnel enter the information on the form into the PACS visitor management function. This
information is then used to conduct a search of the National Crime Information Center (NCIC) to
determine if there are any criminal records or outstanding arrest warrants for the individual. The results
of the NCIC check are entered into PACS. If there is no disqualifying information, such as an

outstanding arrest warrant, the visitor is cleared for access. Access requests by foreign visitors 4 (non-U.S.
citizens and non-Legal Permanent Residents) are processed through the DHS Foreign National Visitor
Management System (FNVMS). 5
C) Parking Permit Management – The Office of the Chief Administrative Officer (OCAO) uses
PACS to issue and track parking permits for the NAC. OCAO personnel access PACS to determine if an
individual is eligible to receive a parking permit. Once determined to be eligible, the individual must
submit General Services Administration (GSA) Parking Application, Form 2941. Upon issuance of the
parking permit, OCAO personnel enter into PACS the name and e-mail address of the permit holder, the
permit number and type, issue date, and expiration date.
D) Alarm Monitoring and Intrusion Detection – The PACS alarm monitoring application allows
OCSO personnel to monitor the Intrusion Detection System (IDS). A record is created in PACS of all
IDS alarm activations or other issues, such as communication and power failures for example. The IDS
in PACS consists of sensors, lights, and other mechanisms through which OCSO can detect the
unauthorized intrusion of persons or devices. The only PII collected by the PACS IDS suite is the first
and last name of the individual authorized to turn the alarm system on and off and the corresponding PIN
number which the individual inputs into the alarm keypad to activate or deactivate the alarm.
To the extent that other Departmental components use a system(s) that operates in the same way
as PACS and will follow the rules outlined in this PIA, that system will be covered by this PIA and listed
as part of an update to this PIA appendix.

Section 1.0 Authorities and Other Requirements
1.1

What specific legal authorities and/or agreements permit
and define the collection of information by the project in
question?
The Chief Security Officer is responsible for developing and implementing
security policies, programs, and standards to protect and safeguard the Department's
personnel, property, facilities, and information. To do this, the OCSO and PHYSD have
established access control policies designed to limit access to authorized individuals. In
order to know if an individual is authorized access, the identity of the individual must be
established. OCSO PHYSD does this by obtaining PII related to the individual and then
conducting appropriate checks of records maintained by DHS and other U.S. government
agencies. Authorities associated with protecting federal property and information
include:
•
•

records are stored under lock and key in NAC Building 2. During the transition to the
new parking program, new records are stored under lock and key in NAC Building 7.
Only designated parking or facilities personnel have access to documents in either
location. Within 60 days after the information is entered into the parking portion of
PACS, the paper records are destroyed. Alarm monitoring and intrusion detection
incident longs are maintained for two years after final entry and then destroyed.

1.5

If the information is covered by the Paperwork Reduction
0.Act (PRA), provide the OMB Control number and the
agency number for the collection. If there are multiple
forms, include a list in an appendix.
OCSO is working with the PRA program management office to address
clearance requirements.

Section 2.0 Characterization of the Information
The following questions are intended to define the scope of the information requested and/or
collected, as well as reasons for its collection.

2.1

Identify the information the project collects, uses,
disseminates, or maintains.
PACS uses PII collected from individuals requiring access to confirm the identity
of the individual and determine their access eligibility. PII is entered into PACS by
OCSO personnel assigned to PHYSD or OCAO.
The following data is collected and entered into PACS to identify individuals
authorized to access DHS HQ facilities in the NCR, primarily the NAC:
•
•
•
•
•
•
•
•
•
•
•

2.2

What are the sources of the information and how is the
information collected for the project?
For facility access purposes, the sources of PACS information are the
individual’s PIV card and DHS Form 11000-14, Identification Access Card Control
Request.
For visitor management purposes, the source of PACS information is DHS Form
11000-13, Visitor Processing Information and information provided by foreign national
visitors.
The information source for NAC parking permits is General Services
Administration (GSA) Form 2941.

2.3

Does the project use information from commercial sources
or publicly available data? If so, explain why and how this
information is used.
PACS does not use commercial or publicly available data.

2.4

Discuss how accuracy of the data is ensured.
The information collected on DHS personnel and contractor employees is
verified against information contained in the OCSO Integrated Security Management
System (ISMS). 6 Information provided by visitors or parking permit applicants will not
be confirmed unless a situation develops that would cause OCSO to question the
accuracy of the information. Checks conducted on visitors are based upon the
information provided by the visitor. DHS does not investigate the visitor to determine if
the information provided by the visitor is valid.

2.5

Privacy Impact Analysis: Related to Characterization of the
Information
Privacy Risk: There is a risk associated with the accuracy of data included in the
PACS. Although most of the PII data is generated by the individual, it is possible that
data associated with individuals with the same name or similar names could be
inaccurately entered.
Mitigation: To address potential occurrences of data being inaccurately entered
the following mitigation strategies are used: Electronic data collection tools are used to
the greatest extent possible and SSN is used to increase accuracy of subject identification.

Section 3.0 Uses of the Information
The following questions require a clear description of the project’s use of information.

3.1

Describe how and why the project uses the information.
PACS uses PII in order to authenticate the identity of federal employees, DHS
contractor employees, and visitors who are authorized entry. OCSO uses this information
to verify the identity of individuals and, in the event of an emergency, contact the
individual. PACS also contains information on vehicles for which a permanent parking
permit has been issued or a daily permit for a vehicle carrying a visitor to the NAC.
The IDS function within PACS monitors activity within sensitive or classified
areas and records the name and pin number of the individual who activates or deactivates
an alarm.

3.2

Does the project use technology to conduct electronic
searches, queries, or analyses in an electronic database to
discover or locate a predictive pattern or an anomaly? If
so, state how DHS plans to use such results.
PII in PACS is used to manage access control, physical access devices, and
intrusion detection at facilities. There are no in-build data analysis functions to identify
patterns or new areas of concern.

3.3

Are there other components with assigned roles and
responsibilities within the system?
Only OCSO, OCAO, and the Office of the Chief Information Officer (OCIO)
have assigned roles and responsibilities in PACS.

3.4

Privacy Impact Analysis: Related to the Uses of
Information
Privacy Risk: There is a privacy risk associated with the handling of PII.
Privacy risks associated with the handling of PII occur when data is extracted from the
system and the individual using the data improperly distributes or stores the data.
Privacy Risk: There is also a privacy risk associate with the system security
concern of an “insider threat” where an individual authorized access to the system
conducts unauthorized activities, such as attempting to access information for which they
do not have permission.
Mitigation: To address both of these risks the following controls and mitigation
strategies are in place:

Privacy Impact Assessment
Department of Homeland Security
Office of the Chief Security Officer
Physical Access Control (PACS) System PIA
Page 8

Handling of PII
• Access to information is granted on a “need to know” basis;
• Access to PACS requires a DHS domain account and requires that the user be logged
into a DHS Intranet accessible computer;
• PACS user accounts are individually approved by the Chief of the PHYSD;
• All users have received DHS computer security training and have been vetted and/or
cleared for access to sensitive, and/or classified information;
• Access to PACS is role-based and users of the system have access to a limited subset
of data based on the concept of least privilege/limited access; and
• Write capability, which is limited to a few roles, is tracked and audited.
System Security
• When information is stored as an attachment on the server, file access will be
restricted by file permissions to prevent access by those without an appropriate
requirement for access;
• All automated data processing equipment supporting the application environment is
located in a DHS data center;
• Specific security roles have been defined and implemented within the application to
control access to information;
• A system security certification was performed and obtained in accordance with the
Office of Management and Budget (OMB) Circular A-130, Appendix III, Security of
Federal Automated Information Resources; and
• Network access to the application is made via a Secure Sockets Layer (SSL)
connection to the ISMS environment.

Section 4.0 Notice
The following questions seek information about the project’s notice to the individual about the information
collected, the right to consent to uses of said information, and the right to decline to provide information.

4.1

How does the project provide individuals notice prior to the
collection of information? If notice is not provided, explain
why not.
Individuals are provided notice at the time of collection by a Privacy Act Notice
on the bottom of the information collection form. The Privacy Act Notice explains the
reasons for collecting information, the consequences of failing to provide the requested
information, and how the information is used. The collection, maintenance, and
disclosure of information complies with the Privacy Act as noted in DHS/ALL – 023
Personnel Security Management, January 16, 2009, 74 FR 3084; DHS/ALL – 024
Facility and Perimeter Access Control and Visitor Management, January 16, 2009, 74 FR
3081; and DHS/ALL – 026 Personal Identity Verification Management System,
September 25, 2009, 74 FR 30301.
Visitors to the NAC must agree with the Privacy Act Statement provided at the
time the visitor is processed for access to the NAC.

Privacy Impact Assessment
Department of Homeland Security
Office of the Chief Security Officer
Physical Access Control (PACS) System PIA
Page 9

4.2

What opportunities are available for individuals to consent
to uses, decline to provide information, or opt out of the
project?
Employees and contractor employees who opt not to provide information will not
be granted access to DHS facilities since PACS will not have the ability to manage the
electronic access points and alarms through which they must pass.
Visitors are advised that access control procedures require the submission of their
PII. They are also advised that DHS will use this information to determine if access may
be granted and that failure to furnish the requested information may delay or prevent their
access.

4.3

Privacy Impact Analysis: Related to Notice
Information collected in association with the DHS PIV card, and used to manage
access control within PACS, is completed in accordance with federal personnel security
standards and requirements.
Visitors and foreign national visitors from whom data is collected may use a
representative, (e.g., Executive Assistant or Embassy staff) to provide the data.
Accordingly, there is a risk that the representative may not convey the Privacy Act Notice
explaining why DHS is requesting the information and how the information will be used
and stored. This PIA serves as an additional notice as well as a further explanation
regarding the way DHS receives and manages PACS data. Notice is also provided
through DHS/ALL – 024 Facility and Perimeter Access Control and Visitor
Management, January 16, 2009, 74 FR 3081.

Section 5.0 Data Retention by the project
The following questions are intended to outline how long the project retains the information after the initial
collection.

5.1

Explain how long and for what reason the information is
retained.
DHS personnel and security records relating to individuals are retained and
disposed of in accordance with GRS 18, item 22a and 22c, as approved by NARA.
Records are destroyed upon notification of death or not later than five years after
separation or transfer of the employee, whichever is first. The index to personnel security
case files are destroyed with the related case.
Visitor records are retained in accordance with GRS 18, Item 17 and are
destroyed five years after final entry or five years after the date of the document, as
appropriate.

Privacy Impact Assessment
Department of Homeland Security
Office of the Chief Security Officer
Physical Access Control (PACS) System PIA
Page 10

Where records are used as evidence in an investigation or in an administrative,
litigation, or other proceeding, the records will be retained until final disposition of the
investigation or proceeding.

5.2

Privacy Impact Analysis: Related to Retention
Risks associated with the retention and disposal of records collected in PACS are
minimal. Risk is present when information for PACS is provided on paper form by the
applicant. The risk is mitigated by security procedures in handling the data and
destroying the files in accordance with the GRS.

Section 6.0 Information Sharing
The following questions are intended to describe the scope of the project information sharing external to
the Department. External sharing encompasses sharing with other federal, state and local government, and private
sector entities.

6.1

Is information shared outside of DHS as part of the normal
agency operations? If so, identify the organization(s) and
how the information is accessed and how it is to be used.
Information contained in PACS for access management purposes is not shared
outside of DHS as part of the normal agency operations.
Visitor management information is shared outside PACS as part of normal
operations for conducting record checks on the individual with other U.S. government
agencies. The U.S. government agency to which the information is sent uses the
information to search its records for information about the individual. Each agency
maintains its records in accordance with its privacy policies. Some record checks are
conducted with U.S. government agencies that maintain national security systems
consistent with the requirements of Executive Order 12333, as amended, “United States
Intelligence Activities.”

6.2

Describe how the external sharing noted in 6.1 is
compatible with the SORN noted in 1.2.
Routine uses of records in PACS associated with visitors accessing DHS
facilities are addressed in DHS/ALL – 023 Personnel Security Management, January 16,
2009, 74 FR 3084; DHS/ALL – 024 Facility and Perimeter Access Control and Visitor
Management, January 16, 2009, 74 FR 3081; and DHS/ALL – 026 Personal Identity
Verification Management System, September 25, 2009, 74 FR 30301.

6.3

Does the project place limitations on re-dissemination?
No limitations are placed on re-dissemination of information within DHS as long

Privacy Impact Assessment
Department of Homeland Security
Office of the Chief Security Officer
Physical Access Control (PACS) System PIA
Page 11

as there is an official need to know.

6.4

Describe how the project maintains a record of any
disclosures outside of the Department.
PACS contains a field which maintains a record of the type of check conducted
on the visitor as well as the agency with which it was conducted.

6.5

Privacy Impact Analysis: Related to Information Sharing
Privacy Risk: As discussed in Section 3.4, there is the potential for an individual
authorized to access the system to conduct unauthorized activities such as attempting to
access information or extracting and sharing information for which they do not have
permission.
Mitigation: To address this risk the following controls are in place:
•

•
•
•
•
•
•

A data/report request form must be completed, signed, and approved by the requester,
requester’s manager, and their Division Chief prior to the creation and/or distribution
of personnel security data to avoid accidental, inappropriate, or unauthorized use of
the data;
Access to information is granted on a “need to know” basis;
Access to FNVMS requires a DHS domain account and requires that the user be
logged into a DHS Intranet accessible computer;
FNVMS user accounts are individually approved by OCSO and the Chief of ISID;
All users have received DHS computer security training and have been vetted and/or
cleared for access to privacy, sensitive, and/or classified information;
Access to FNVMS is role-based and users of the system have access to a limited
subset of data based on the concept of least privilege/limited access; and
Write capability is limited to a few roles and is tracked and audited.

Section 7.0 Redress
The following questions seek information about processes in place for individuals to seek redress which
may include access to records about themselves, ensuring the accuracy of the information collected about them,
and/or filing complaints.

7.1

What are the procedures that allow individuals to access
their information?
Once data is submitted to OCSO for entry in PACS the individual who submitted
the information must contact OCSO directly or submit a Privacy Act (PA) or Freedom of
Information Act (FOIA) request to gain access to their PII and request that it be
corrected. Individuals have the ability to address and provide updated information.
OCSO may be contacted through its Customer Service Center at 202-447-5010 or by
email at [email protected].

Privacy Impact Assessment
Department of Homeland Security
Office of the Chief Security Officer
Physical Access Control (PACS) System PIA
Page 12

7.2

What procedures are in place to allow the subject
individual to correct inaccurate or erroneous information?
OCSO will make changes to employee and contractor employee PACS records as
long as the information is consistent with information ISMS. Changes will be made to
visitor records if the change requested can be verified.

7.3

How does the project notify individuals about the
procedures for correcting their information?
Instructions are provided on the respective form for making changes or updates
to data that may be necessary after original submission. If an individual needs to make
changes to enhance the accuracy of the information, the individual may contact OCSO
through its Customer Service Center at 202-447-5010 or by email at
[email protected].

7.4

Privacy Impact Analysis: Related to Redress
Information contained in PACS may be corrected by contacting OCSO through
its Customer Service Center at 202-447-5010 or by email at [email protected]
or through redress procedures afforded under the PA and FOIA.

Section 8.0 Auditing and Accountability
The following questions are intended to describe technical and policy based safeguards and security
measures.

8.1

How does the project ensure that the information is used in
accordance with stated practices in this PIA?
All PACS user access is based on pre-defined system owner and management
authorized job roles and official duties. These roles and policies are enforced through use
of access control lists. As such, PACS users may only input, update, and delete records
or fields to which they are authorized to have access and a need-to-know, as prescribed
by the application user manual and system administration procedures.
Additionally, access control software on PACS prevents users from having all of
the necessary authority or information access to perform fraudulent activity without
collusion.

8.2

Describe what privacy training is provided to users either
generally or specifically relevant to the project.
All DHS employees and assigned contractor staff receive privacy and security
training, and have undergone necessary suitability investigations and/or received security

Privacy Impact Assessment
Department of Homeland Security
Office of the Chief Security Officer
Physical Access Control (PACS) System PIA
Page 13

clearances for access to classified national security information and facilities.
Additionally, standard operating procedures and system user manuals describe in detail
user responsibilities and training requirements.

8.3

What procedures are in place to determine which users
may access the information and how does the project
determine who has access?
PACS user accounts are individually approved by the OCSO PHYSD, Access
Control Branch Chief, and authorized by the Chief of the Systems Security Division. All
users must have received DHS computer security training and have been vetted for access
to DHS IT systems or for access to classified national security information. Furthermore,
access to PACS is role-based and users of the system have access to a limited subset of
data based on the concept of least privilege/limited access.

Privacy Impact Assessment

8.4

How does the project review and approve information
sharing agreements, MOUs, new uses of the information,
new access to the system by organizations within DHS and
outside?

.

PACS establishes data sharing agreements with external entities using
Interconnection Security Agreements (ISAs). DHS 4300A, Sensitive System Handbook,
September 2008, establishes this requirement for DHS systems. An ISA is required
whenever the security policies of the interconnected systems are not identical and the
systems are not administered by the same entity/Designated Accrediting Authority
(DAA). The ISA documents the security protections that must operate on interconnected
systems to ensure that transmissions between systems permit only acceptable
transactions. The ISA includes descriptive, technical, procedural, and planning
information. It also formalizes the security understanding between the authorities
responsible for the electronic connection between the systems. The DAA for each
organization is responsible for reviewing and signing the ISA.
