Assessment Title
Rule Text
The application must implement NSA-approved cryptography to protect classified information in accordance with applicable federal laws, Executive Orders, directives, policies, regulations, and standards.
Description
Discussion Text
Use of weak or untested encryption algorithms undermines the purposes of utilizing encryption to protect classified data. The application must implement cryptographic modules adhering to the higher standards approved by the federal government since this provides assurance they have been tested and validated.
