Requirements NIST SOURCE

Restrict access to media storage areas and log access attempts and access granted using [organization-defined automated mechanisms].

Discussion (NIST Supplemental Guidance)

Automated mechanisms include keypads, biometric readers, or card readers on the external entries to media storage areas.

Engineering Interpretation

Original engineering commentary written for this explorer — not NIST source text and not authoritative guidance.

No engineering interpretation has been authored for MP-4(2) yet. This section is architected to receive it — see the Requirements and Assessment sections above for the authoritative NIST source content in the meantime.

Assessment

NIST SP 800-53A REV 5.2.0

Assessment Objectives

  1. automated mechanisms to restrict access to media storage areas are defined;
  2. automated mechanisms to log access attempts to media storage areas are defined;
  3. automated mechanisms to log access granted to media storage areas are defined;
  4. access to media storage areas is restricted using <MP-04(02)_ODP[01] automated mechanisms>;
  5. access attempts to media storage areas are logged using <MP-04(02)_ODP[02] automated mechanisms>;
  6. access granted to media storage areas is logged using <MP-04(02)_ODP[03] automated mechanisms>.

Examine

[SELECT FROM: System media protection policy; procedures addressing media storage; access control policy and procedures; physical and environmental protection policy and procedures; system design documentation; system configuration settings and associated documentation; media storage facilities; access control devices; access control records; audit records; system security plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel with system media protection and storage responsibilities; organizational personnel with information security responsibilities; system/network administrators].

Test

[SELECT FROM: Automated mechanisms restricting access to media storage areas; automated mechanisms auditing access attempts and access granted to media storage areas].

Overlays

Showing the OT/ICS overlay for the parent control MP-4 — see the MP-4(2) entries within each baseline below.

OT/ICS Overlay SP 800-82r3

NIST SP 800-82r3 Appendix F, Table 22. Blank baseline means the control/control enhancement is not selected in that initial OT baseline.

LOW

Not applicable at this tier.

MODERATE

  • Base control: Included (matches standard baseline)

HIGH

  • Base control: Included (matches standard baseline)

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for MP-4(2). This section is architected to display, per product: STIG ID, Finding ID, Severity, Title, Description, Check, Fix, CCI, and NIST control mapping — but nothing is populated here until a real DISA STIG/CCI dataset is ingested.
