13. A security incident has been filed and an employee believes that someone has been on the computer since the employee left last night.

Which Microsoft Windows tool would be used by the security analyst to determine if and when someone logged on to the computer after working hours?
- Event Viewer
- Performance Monitor
- Task Manager
Explanation: Event Viewer is used to investigate the history of application, security, and system events. Events show the date and time that the event occurred along with the source of the event. If a cybersecurity analyst has the address of the Windows computer targeted or the date and time that a security breach occurred, the analyst could use Event Viewer to document and prove what occurred on the computer.
