Session auditing enables detection of unauthorized exposure or access to sensitive information during user activities.
Privacy and security architectures require controls to protect sensitive information from unauthorized exposure across the system lifecycle.
Inventory identifies all systems holding or processing data, enabling detection of unauthorized exposure paths before exploitation.
Protection planning for critical infrastructure directly calls for authentication of access to essential functions before any operation is permitted.
Risk assessments evaluate exposure of critical functions lacking authentication and prioritize corrective controls.
Requires authentication gates on critical functions that must remain unavailable to anonymous public users.
Treats remote activation of surveillance-capable devices as a critical function that must be disabled or authenticated.
Decoys supply misleading data and log access attempts, directly detecting and deflecting unauthorized information exposure.
