SC-40(4)—Wireless Link Protection
Technical
>Control Description
WIRELESS LINK PROTECTION | SIGNAL PARAMETER IDENTIFICATION The information system implements cryptographic mechanisms to prevent the identification of ⚙organization-defined wireless transmitters by using the transmitter signal parameters.
>Supplemental Guidance
Radio fingerprinting techniques identify the unique signal parameters of transmitters to fingerprint such transmitters for purposes of tracking and mission/user identification. This control enhancement protects against the unique identification of wireless transmitters for purposes of intelligence exploitation by ensuring that anti-fingerprinting alterations to signal parameters are not predictable by unauthorized individuals. This control enhancement helps assure mission success when anonymity is required.
