Requirements NIST SOURCE

Employ [one of: full-device encryption; container-based encryption] to protect the confidentiality and integrity of information on [mobile devices].

Discussion (NIST Supplemental Guidance)

Container-based encryption provides a more fine-grained approach to data and information encryption on mobile devices, including encrypting selected data structures such as files, records, or fields.

Engineering Interpretation

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

No engineering interpretation has been authored for AC-19(5) 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. one of the following PARAMETER VALUES is selected: {full-device encryption; container-based encryption};
  2. mobile devices on which to employ encryption are defined;
  3. <AC-19(05)_ODP[01] SELECTED PARAMETER VALUE> is employed to protect the confidentiality and integrity of information on <AC-19(05)_ODP[02] mobile devices>.

Examine

[SELECT FROM: Access control policy; procedures addressing access control for mobile devices; system design documentation; system configuration settings and associated documentation; encryption mechanisms and associated configuration documentation; system audit records; system security plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel with access control responsibilities for mobile devices; system/network administrators; organizational personnel with information security responsibilities].

Test

[SELECT FROM: Encryption mechanisms protecting confidentiality and integrity of information on mobile devices].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for AC-19(5). 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.
