Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

EMP protection directly addresses an artificially induced physical/environmental threat.

Safe-mode entry on detected adverse conditions reduces impact without eliminating the root handling weakness.

Fire detection and suppression directly stops fire (an environmental condition) from damaging the system.

Maintaining temperature and humidity levels prevents environmental conditions from affecting system operation.

Isolation valves and shutoffs stop water damage (environmental condition) from reaching the system.

Known-state failure on component or environmental faults limits blast radius.

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

PR.IR-02 full match
prevents

Explicit protection of assets from environmental threats is the core mitigation for improper handling of those conditions.

DE.CM-02 mostly match
prevents

Monitoring the physical environment directly surfaces the conditions the weakness fails to handle.

PR.IR-03 partial match
prevents

Resilience mechanisms help withstand adverse environmental situations but do not specifically address detection or handling of the conditions themselves.

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.

degrades

Directly requires protection against physical and environmental threats that the weakness describes.

prevents

Ensures supporting utilities (power, HVAC) are protected, mitigating environmental-condition failures.

finds

Physical security monitoring can detect environmental anomalies or tampering.

mitigates

Ensures information security is maintained during physical or environmental disruptions.

mitigates

ICT readiness for business continuity includes resilience to environmental conditions.

mitigates

Physical perimeters reduce exposure to external environmental threats.
