Requirements NIST SOURCE

Restrict access to [organization-defined types of digital and/or non-digital media] to [organization-defined personnel or roles].

Discussion (NIST Supplemental Guidance)

System media includes digital and non-digital media. Digital media includes flash drives, diskettes, magnetic tapes, external or removable hard disk drives (e.g., solid state, magnetic), compact discs, and digital versatile discs. Non-digital media includes paper and microfilm. Denying access to patient medical records in a community hospital unless the individuals seeking access to such records are authorized healthcare providers is an example of restricting access to non-digital media. Limiting access to the design specifications stored on compact discs in the media library to individuals on the system development team is an example of restricting access to digital media.

Assessment

NIST SP 800-53A REV 5.2.0

Assessment Objectives

  1. types of digital media to which access is restricted are defined;
  2. personnel or roles authorized to access digital media is/are defined;
  3. types of non-digital media to which access is restricted are defined;
  4. personnel or roles authorized to access non-digital media is/are defined;
  5. access to <MP-02_ODP[01] types of digital media> is restricted to <MP-02_ODP[02] personnel or roles>;
  6. access to <MP-02_ODP[03] types of non-digital media> is restricted to <MP-02_ODP[04] personnel or roles>.

Examine

[SELECT FROM: System media protection policy; procedures addressing media access restrictions; access control policy and procedures; physical and environmental protection policy and procedures; media storage facilities; access control records; system security plan; other relevant documents or records].

Interview

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

Test

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

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for MP-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.
