PE-2: PHYSICAL ACCESS AUTHORIZATIONS
TAILORED FOR INDUSTRIAL CONTROL SYSTEMS
ICS Control Baselines:
- Low
- Moderate
- High
The organization:
- a. Develops, approves, and maintains a list of individuals with authorized access to the facility where the information system resides;
- b. Issues authorization credentials for facility access;
- c. Reviews the access list detailing authorized facility access by individuals [Assignment: organization-defined frequency]; and
- d. Removes individuals from the facility access list when access is no longer required.
SUPPLEMENTAL GUIDANCE
This control applies to organizational employees and visitors. Individuals (e.g., employees, contractors, and others) with permanent physical access authorization credentials are not considered visitors. Authorization credentials include, for example, badges, identification cards, and smart cards. Organizations determine the strength of authorization credentials needed (including level of forge-proof badges, smart cards, or identification cards) consistent with federal standards, policies, and procedures. This control only applies to areas within facilities that have not been designated as publicly accessible.
ICS SUPPLEMENTAL GUIDANCE
No ICS Supplemental Guidance.

CONTROL ENHANCEMENTS
PE-2 (1) PHYSICAL ACCESS AUTHORIZATIONS | ACCESS BY POSITION / ROLE
NOT SELECTED FOR THE NIST ISC CONTROL SET
The organization authorizes physical access to the facility where the information system resides based on position or role.
Supplemental Guidance: NONE
RELATED CONTROLS: PE-2 (1)
PE-2 (2) PHYSICAL ACCESS AUTHORIZATIONS | TWO FORMS OF IDENTIFICATION
NOT SELECTED FOR THE NIST ISC CONTROL SET
The organization requires two forms of identification from [Assignment: organization-defined list of acceptable forms of identification] for visitor access to the facility where the information system resides.
Supplemental Guidance:
Acceptable forms of government photo identification include, for example, passports, Personal Identity Verification (PIV) cards, and drivers' licenses. In the case of gaining access to facilities using automated mechanisms, organizations may use PIV cards, key cards, PINs, and biometrics.
RELATED CONTROLS: PE-2 (2)
PE-2 (3) PHYSICAL ACCESS AUTHORIZATIONS | RESTRICT UNESCORTED ACCESS
NOT SELECTED FOR THE NIST ISC CONTROL SET
The organization restricts unescorted access to the facility where the information system resides to personnel with [Selection (one or more): security clearances for all information contained within the system; formal access authorizations for all information contained within the system; need for access to all information contained within the system; [Assignment: organization-defined credentials]].
Supplemental Guidance:
Due to the highly sensitive nature of classified information stored within certain facilities, it is important that individuals lacking sufficient security clearances, access approvals, or need to know, be escorted by individuals with appropriate credentials to ensure that such information is not exposed or otherwise compromised.
