Control Statement
Employ [Assignment: organization-defined protective measures] against electromagnetic pulse damage for [Assignment: organization-defined system and system components].
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.
OT Discussion
Organizations that manage OT equipment may choose to utilize EMP protection to prevent adversarial or environmental electromagnetic threats. Organizations may select to follow National Coordinating Center for Communications (NCC) [guidelines on EM pulse protection.](https://www.cisa.gov/sites/default/files/publications/19_0307_CISA_EMP-Protection-Resilience-Guidelines.pdf)
