Reduce Detection Potential
LOW MODERATE HIGHRequirements NIST SOURCE
Implement cryptographic mechanisms to reduce the detection potential of wireless links to [level of reduction].
Discussion (NIST Supplemental Guidance)
The implementation of cryptographic mechanisms to reduce detection potential is used for covert communications and to protect wireless transmitters from geo-location. It also ensures that the spread spectrum waveforms used to achieve a low probability of detection are not predictable by unauthorized individuals. Mission requirements, projected threats, concept of operations, and applicable laws, executive orders, directives, regulations, policies, and standards determine the levels to which wireless links are undetectable.

Assessment
Assessment Objectives
- the level of reduction to be achieved to reduce the detection potential of wireless links is defined;
- cryptographic mechanisms to reduce the detection potential of wireless links to <SC-40(02)_ODP level of reduction> are implemented.

STIGs & CCIs
No STIG checks or CCI mappings are currently loaded for SC-40(2). 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.
