Discussion (NIST Supplemental Guidance)

Security marking refers to the application or use of human-readable security attributes. Digital media includes diskettes, magnetic tapes, external or removable hard disk drives (e.g., solid state, magnetic), flash drives, compact discs, and digital versatile discs. Non-digital media includes paper and microfilm. Controlled unclassified information is defined by the National Archives and Records Administration along with the appropriate safeguarding and dissemination requirements for such information and is codified in 32 CFR 2002 . Security markings are generally not required for media that contains information determined by organizations to be in the public domain or to be publicly releasable. Some organizations may require markings for public information indicating that the information is publicly releasable. System media marking reflects applicable laws, executive orders, directives, policies, regulations, standards, and guidelines.

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-3 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. types of system media exempt from marking when remaining in controlled areas are defined;
  2. controlled areas where media is exempt from marking are defined;
  3. system media is marked to indicate distribution limitations, handling caveats, and applicable security markings (if any) of the information;
  4. <MP-03_ODP[01] types of media exempted from marking> remain within <MP-03_ODP[02] controlled areas>.

Examine

[SELECT FROM: System media protection policy; procedures addressing media marking; physical and environmental protection policy and procedures; list of system media marking security attributes; designated controlled areas; system security plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel with system media protection and marking responsibilities; organizational personnel with information security responsibilities].

Test

[SELECT FROM: Organizational processes for marking information media; mechanisms supporting and/or implementing media marking].

Overlays

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-3. 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.
