Where can you monitor Fortigate administrator logins, system activity, and failed authentications?

The appropriate location to monitor Fortigate administrator logins, system activity, and failed authentications is within the specified section dedicated to failed authentication attempts. This section provides detailed information specifically related to login attempts that did not succeed, including relevant timestamps, sources of attempts, and reasons for failures. This makes it a vital resource for security audits, helping administrators track unauthorized access attempts and ensuring system security by responding appropriately.

The other options focus on different aspects of system logs and activities. For example, while monitoring admin actions may provide valuable insights into changes made by administrators, it does not specifically target failed authentication attempts or login statuses. The user activity section is more focused on end-user interactions rather than administrative logins, and event logs might aggregate numerous types of system events without specifically emphasizing authentication failures. Thus, the second choice stands out as the most directly relevant for tracking failed authentications.
