Which policy is used to monitor user access to administrative privileges?

User account control (UAC) monitoring is specifically designed to enhance security by managing and auditing user access to administrative privileges. UAC serves as a protective mechanism that restricts the actions users can take, particularly those that require administrative rights. By monitoring UAC, organizations can track when users attempt to perform actions that necessitate elevated privileges, providing an audit trail of who accessed administrative capabilities and when.

This monitoring capability allows for better management of potential risks associated with unauthorized access, as any elevation of privileges is logged and can be reviewed for compliance and security purposes. Understanding this activity is crucial for maintaining a secure environment, preventing misuse, and identifying any suspicious behavior related to privileged access.

In contrast, the other options do not specifically focus on monitoring user access to administrative privileges in the same targeted way. Service Access policies and Offline Policy Authorization relate more to service controls and permissions management. Endpoint sign-in policies focus on the authentication process rather than the management or oversight of administrative privilege usage. Therefore, UAC monitoring stands out as the appropriate selection for this context.
