SC-40(2)—Wireless Link Protection
Technical
>Control Description
WIRELESS LINK PROTECTION | REDUCE DETECTION POTENTIAL The information system implements cryptographic mechanisms to reduce the detection potential of wireless links to ⚙organization-defined level of reduction.
>Supplemental Guidance
This control enhancement is needed for covert communications and protecting wireless transmitters from being geo-located by their transmissions. The control enhancement ensures that spread spectrum waveforms used to achieve low probability of detection are not predictable by unauthorized individuals. Mission requirements, projected threats, concept of operations, and applicable legislation, directives, regulations, policies, standards, and guidelines determine the levels to which wireless links should be undetectable.
