    How to identify Unauthorized access from event log?


    I had left my laptop in college lab after locking it. Not sure if I had left it in sleep mode.

    Today when I checked the event log has an entry at a time I wasn't there!The system has returned from a low power state. I left the lab at 12:30. Log has an entry in power troubleshooter at 12:32.

    Will there be such an entry even when someone just press some key?

    Or was there a successful logon attempt?

    Check security logs. It could be, that Windows was performing some maintenance.

    I checked the security log.

    There is a special logon at 12:31:57

    PC woke up at 12:32

    But there are far more entries of special logon. No entry at same timestamp in Return from sleep mode.

    So this one entry looks a bit suspicious to me
