Mitigating Controls (NIST 800-53 r5) AI

Requires establishing the most restrictive configuration settings, which directly overrides or prevents use of insecure default variable initializations.

Requires maintaining a documented baseline configuration that can enforce secure initial values instead of insecure defaults.

Mandates application of security engineering principles during development that include use of secure defaults and proper variable initialization.

Maintaining separate execution domains for each process structurally eliminates unintended concurrent access to the same shared resources.

Preventing unintended information transfer through shared system resources directly addresses the improper concurrent modification that defines a race condition.

finds

Security testing can detect insecure defaults but does not prevent them.

prevents

Configuration management enforces secure default values and prevents insecure initialization.

prevents

Secure development life cycle requires explicit secure initialization of variables.

prevents

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

prevents

Secure architecture principles include avoiding insecure defaults in design.

prevents

Secure coding standards mandate explicit, safe variable initialization.
