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-693

Implements a reliable, tamperproof protection mechanism whose completeness can be assured.

addresses: CWE-693

Procedures for training on protection mechanisms reduce the chance of protection mechanism failures being present or exploitable.

addresses: CWE-693

Documented procedures to implement assessment, authorization, and monitoring controls prevent these protection mechanisms from failing due to undefined processes.

addresses: CWE-693

Direct evaluation of whether controls produce desired security outcomes detects protection mechanism failures and enables remediation.

addresses: CWE-693

Requires assessment that protection mechanisms are correctly implemented and producing intended security outcomes.

addresses: CWE-693

The POA&M process ensures identified weaknesses in protection mechanisms are documented and scheduled for remediation, reducing the duration they remain exploitable.

addresses: CWE-693

Ongoing control assessments and analysis of monitoring data enable timely detection and response when protection mechanisms fail.

addresses: CWE-693

Impact analysis identifies changes that could weaken or disable existing protection mechanisms.
