Control statement

Protect the system from information leakage due to electromagnetic signals emanations.

NIST discussion

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.

Control enhancements

PE-19(1) National Emissions Policies and Procedures

Baselines: Not in a baseline

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 and assessment objectives for PE-19(1)

Emissions Security (EMSEC) policies include the former TEMPEST policies.

Determine if:

• PE-19(01)[01] system components are protected in accordance with national emissions security policies and procedures based on the security category or classification of the information;
• PE-19(01)[02] associated data communications are protected in accordance with national emissions security policies and procedures based on the security category or classification of the information;
• PE-19(01)[03] networks are protected in accordance with national emissions security policies and procedures based on the security category or classification of the information.

Examine: Physical and environmental protection policy; procedures addressing information leakage that comply with national emissions and TEMPEST policies and procedures; system component design documentation; system configuration settings and associated documentation system security plan; other relevant documents or records.

Interview: Organizational personnel with responsibilities for system environmental controls; organizational personnel with information security responsibilities.

Test: Information system components for compliance with national emissions and TEMPEST policies and procedures.

Assessment objectives (SP 800-53A)

Objectives and methods for PE-19

Determine if the system is protected from information leakage due to electromagnetic signal emanations.

Examine: Physical and environmental protection policy; procedures addressing information leakage due to electromagnetic signal emanations; mechanisms protecting the system against electronic signal emanations; facility housing the system; records from electromagnetic signal emanation tests; system security plan; other relevant documents or records.

Interview: Organizational personnel with responsibilities for system environmental controls; organizational personnel with information security responsibilities.

Test: Mechanisms supporting and/or implementing protection from information leakage due to electromagnetic signal emanations.
