Information Leakage
LOW MODERATE HIGHRequirements NIST SOURCE
Protect the system from information leakage due to electromagnetic signals emanations.
Discussion (NIST Supplemental Guidance)
Information leakage is the intentional or unintentional release of data or information to an untrusted environment from electromagnetic signals emanations. The security categories or classifications of systems (with respect to confidentiality), organizational security policies, and risk tolerance guide the selection of controls employed to protect systems against information leakage due to electromagnetic signals emanations.
Enhancements NIST SOURCE
PE-19(1) National Emissions Policies and Procedures LOW MODERATE HIGH
Protect system components, associated data communications, and networks in accordance with national Emissions Security policies and procedures based on the security category or classification of the information.
Discussion
Emissions Security (EMSEC) policies include the former TEMPEST policies.

STIGs & CCIs
No STIG checks or CCI mappings are currently loaded for PE-19. 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.
