Employ [protective measures] against electromagnetic pulse damage for [system and system components].

Discussion (NIST Supplemental Guidance)

An electromagnetic pulse (EMP) is a short burst of electromagnetic energy that is spread over a range of frequencies. Such energy bursts may be natural or man-made. EMP interference may be disruptive or damaging to electronic equipment. Protective measures used to mitigate EMP risk include shielding, surge suppressors, ferro-resonant transformers, and earth grounding. EMP protection may be especially significant for systems and applications that are part of the U.S. critical infrastructure.

Assessment

NIST SP 800-53A REV 5.2.0

Assessment Objectives

  1. protective measures to be employed against electromagnetic pulse damage are defined;
  2. system and system components requiring protection against electromagnetic pulse damage are defined;
  3. <PE-21_ODP[01] protective measures> are employed against electromagnetic pulse damage for <PE-21_ODP[02] system and system components>.

Examine

[SELECT FROM: Physical and environmental protection policy; procedures addressing protective measures to mitigate EMP risk to systems and components; documentation detailing protective measures to mitigate EMP risk; list of locations where protective measures to mitigate EMP risk are implemented; system security plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel with responsibilities for physical and environmental protection; system developers/integrators; organizational personnel with information security responsibilities].

Test

[SELECT FROM: Mechanisms for mitigating EMP risk].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for PE-21. 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.
