addresses: CWE-327

Contacts with security groups provide timely information on broken or risky cryptographic algorithms, reducing the likelihood of their selection and use.

addresses: CWE-327

Ongoing education and sharing of recommended practices helps organizations identify and migrate away from broken or risky cryptographic algorithms.

addresses: CWE-327

Cross-organization threat feeds commonly include advances in cryptanalysis and active exploits against weak or broken algorithms, allowing organizations to deprecate them proactively.

addresses: CWE-327

Capital planning and funding allow selection and ongoing support of strong cryptographic algorithms rather than weak or broken ones.

addresses: CWE-327

Risk updates surface newly-broken or risky cryptographic algorithms as threat intelligence and computing advances evolve, enabling timely replacement.

addresses: CWE-327

Scanners flag use of broken or weak cryptographic algorithms via known-vulnerability databases.

addresses: CWE-327

Enforces approved cryptographic algorithms for each use case, blocking use of broken or risky algorithms.

addresses: CWE-327

Flaw remediation replaces broken or risky cryptographic algorithms once safer implementations are released by vendors.
