The requirement, verbatim

NIST SP 800-171 Rev. 2 · 3.10.4
Maintain audit logs of physical access.

Requirement 3.10.4, practice name in the CMMC assessment guide: Physical Access Logs.

NIST's discussion

Organizations have flexibility in the types of audit logs employed. Audit logs can be procedural (e.g., written log of individuals accessing the facility), automated (e.g., capturing ID provided by a PIV card), or some combination thereof. Physical access points can include facility access points, interior access points to systems or system components requiring supplemental access controls, or both. System components (e.g., workstations, notebook computers) may be in areas designated as publicly accessible with organizations safeguarding access to such devices.

NIST SP 800-171 Rev. 2, discussion under 3.10.4. Whitespace normalised; wording unchanged.

Assessment objectives

An assessor decides each of these separately. The requirement is met only when every objective is.

[a] audit logs of physical access are maintained

NIST SP 800-171A, determination statements for 3.10.4.

For assessors: examine, interview, test

NIST SP 800-171A names what an assessor may examine, whom they may interview, and what they may test for this requirement. Assessors select from these lists; they are not a checklist of everything you must produce.

Examine

Physical and environmental protection policy
procedures addressing physical access control
system security plan
physical access control logs or records
inventory records of physical access control devices
system entry and exit points
records of key and lock combination changes
storage locations for physical access control devices
physical access control devices
list of security safeguards controlling access to designated publicly accessible areas within facility
other relevant documents or records

Interview

Personnel with physical access control responsibilities
personnel with information security responsibilities

Test

Organizational processes for physical access control
mechanisms supporting or implementing physical access control
physical access control devices

Evidence

No evidence examples are published for this requirement yet. The objectives above are what an assessor checks; evidence is whatever shows each one is true in your environment, dated and kept with your system security plan.

Scoring weight

Worth 1 point. Not meeting this requirement subtracts 1 from your 110-point SPRS score.

DoD NIST SP 800-171 Assessment Methodology v1.2.1 weighting, as carried in the Bedrock scoring table. The score starts at 110 and subtracts the weight of every requirement not met.

In Rev. 3

Rev. 2 is what your contract requires today. A standing DoD class deviation keeps Rev. 2 in force; NIST has published Rev. 3, but it is not adopted for contracts. In Rev. 3 this requirement is withdrawn and incorporated elsewhere: 03.10.07 Physical Access Control.
