Mitigation

Phase: Architecture and Design

Description:

  • Do not reuse PRNG seeds. Consider a PRNG that periodically re-seeds itself as needed from a high quality pseudo-random output, such as hardware devices.
Mitigation ID: MIT-2

Phases: Architecture and Design, Requirements

Strategy: Libraries or Frameworks

Description:

  • Use products or modules that conform to FIPS 140-2 [REF-267] to avoid obvious entropy problems, or use the more recent FIPS 140-3 [REF-1192] if possible.
