prevents

Mandates use of approved cryptographic controls, directly requiring cryptographically strong RNGs.

detects

Security testing can detect use of weak random number generators.

prevents

Secure SDLC processes should catch weak PRNG usage during design and code review.

prevents

Application security requirements can specify cryptographically strong random number generation.

prevents

Secure engineering principles include selection of appropriate cryptographic primitives.

prevents

Secure coding standards prohibit use of weak PRNGs in security contexts.
