CVE-2026-45353

Authentication of users/services/hardware directly enforces source verification for communication channels.

Verifying identity assertions prevents spoofed channel origins but does not cover all channel-establishment scenarios.

Directly requires defining, enforcing, and reviewing access permissions and least privilege on resources.

Network protections reduce unauthorized channel usage but do not specifically require origin verification at channel setup.

Hardened baselines and configuration management explicitly include correct permission settings for critical resources.

Topic-specific policies on asset management and secure configuration establish expectations for correct permission settings on critical resources, lowering the likelihood that default or overly permissive permissions will be left in place.

Classification results drive the assignment of permissions and handling procedures, decreasing the likelihood that critical resources receive incorrect or overly permissive permission settings.

By requiring owners to determine and document the exact permissions needed for each asset, the control reduces the likelihood that default or overly permissive file and resource permissions will be left in place.

Documented provisioning and revocation procedures reduce the chance that critical resources retain overly permissive default or leftover permissions after personnel changes.

Documented responsibility for protecting assets encourages correct permission settings rather than leaving them at insecure defaults.

Monitoring supplier policy changes and conducting audits can reveal incorrect permission assignments on resources managed by the supplier, prompting corrective action before they are exploited.
