Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires timely remediation of the identified race condition flaw in the SSDP service before local privilege escalation can occur.

prevent

Enforces least privilege on processes and users, limiting both the initial access and the impact of any successful race-condition escalation in the service.

prevent

Provides process isolation that reduces the ability of concurrent threads to improperly share and manipulate SSDP service resources.

detects

Security testing can detect race conditions, but does not prevent them at design or coding time.

prevents

Secure SDLC mandates concurrency controls and synchronization primitives that directly prevent race conditions.

prevents

Application security requirements can specify thread-safety and locking rules, but do not prescribe implementation details.

prevents

Secure architecture principles require proper synchronization and resource isolation, addressing the root cause of CWE-362.

prevents

Secure coding standards explicitly forbid unsafe concurrent access patterns and mandate atomic operations or locks.

none

Change management reduces introduction of concurrency bugs during updates, yet does not address the weakness itself.
