detects

Security testing can detect missing or incorrect privilege handling.

prevents

Defines access-control policy that should prevent insufficient-privilege situations.

degrades

Specifies how access rights are granted, reviewed and revoked, directly addressing privilege handling.

degrades

Requires explicit management of privileged access rights, reducing the chance of missing privilege checks.

prevents

Secure-SDLC practices include privilege checks during design and coding.

prevents

Secure-coding standards require proper permission checks before resource access.
