Mitigating Controls

Likely Mitigating Controls AI

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.

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.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

blocks

Requiring the organization to define and enforce minimum cryptographic strength prevents deployment of insufficient key lengths or weak ciphers that can be brute-forced.

Hardening callouts derived

DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.

  • No fine-grained STIG row for CWE-326, a class-level weakness. Rules are authored against its narrower children: CWE-328.
