Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Maintaining currency with technologies and practices reduces selection of encryption mechanisms that provide inadequate strength.
Updated assessments identify when previously adequate encryption strength no longer meets current attack capabilities or compliance drivers.
Establishment procedures require selection and generation of keys with adequate length and strength for the chosen algorithm.
Specifies required cryptography types and parameters, preventing selection of inadequate encryption strength.
Prompt patching corrects inadequate encryption strength when vendors release updates that increase key sizes or algorithm security.
