Continuously Monitor User Accounts Status Changes in AD to Protect Systems and Data

Automatically locking out accounts after several unsuccessful logon attempts is a common practice, since failed logon attempts can be a sign of an intruder or malware trying to get into your IT system. Before unlocking an account, it’s wise to find out why incorrect passwords were repeatedly provided; otherwise, you increase the risk of unauthorized access to your sensitive data. Therefore, it’s important to continuously monitor which accounts get unlocked and by whom, so you can spot any that were unlocked without proper approval and respond quickly to protect your systems and data.
