Requirements NIST SOURCE

Use lockable physical casings to protect [system components] from unauthorized physical access.

Discussion (NIST Supplemental Guidance)

The greatest risk from the use of portable devices—such as smart phones, tablets, and notebook computers—is theft. Organizations can employ lockable, physical casings to reduce or eliminate the risk of equipment theft. Such casings come in a variety of sizes, from units that protect a single notebook computer to full cabinets that can protect multiple servers, computers, and peripherals. Lockable physical casings can be used in conjunction with cable locks or lockdown plates to prevent the theft of the locked casing containing the computer equipment.

Implementation Guidance

Engineering Interpretation

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

No engineering interpretation has been authored for PE-3(4) 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. system components to be protected from unauthorized physical access are defined;
  2. lockable physical casings are used to protect <PE-03(04)_ODP system components> from unauthorized access.

Examine

[SELECT FROM: Physical and environmental protection policy; procedures addressing physical access control; list of system components requiring protection through lockable physical casings; lockable physical casings; system security plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel with physical access control responsibilities; organizational personnel with information security responsibilities].

Test

[SELECT FROM: Lockable physical casings].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for PE-3(4). 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.
