addresses: CWE-326

Maintaining currency with technologies and practices reduces selection of encryption mechanisms that provide inadequate strength.

addresses: CWE-326

Updated assessments identify when previously adequate encryption strength no longer meets current attack capabilities or compliance drivers.

addresses: CWE-326

Establishment procedures require selection and generation of keys with adequate length and strength for the chosen algorithm.

addresses: CWE-326

Specifies required cryptography types and parameters, preventing selection of inadequate encryption strength.

addresses: CWE-326

Prompt patching corrects inadequate encryption strength when vendors release updates that increase key sizes or algorithm security.
