How do you audit AD user logons

[bob]

You start by making sure auditing is turned on in your group policies. I always check that first when I need to track user activity. It lets events bubble up over time. You wait a bit for the settings to kick in across your setup. Then you head over to the main servers handling logins. But sometimes replication causes delays so you check each one separately. Also you open the event viewer to scan what has collected. Perhaps you focus on recent activity to avoid getting lost in old noise. Now you see patterns emerge from the entries.
You filter those entries by date ranges to narrow things down fast. I do that often because raw logs grow huge quick. It helps spot unusual login times from certain accounts. You look for both good and bad attempts without skipping any. But you might need to repeat the process on backup servers too. Also you compare notes between them for consistency. Perhaps odd failures point to password issues or something else. Then you note the users involved and their origins. You talk to the team about anything suspicious that pops out.
You review failed attempts closely since they often reveal problems early. I found that useful in past checks when accounts got locked unexpectedly. It saves time later when troubleshooting user complaints. But you avoid staring at every single line by sorting smartly. Also you track successful logins to see if anyone accesses odd hours. Perhaps patterns show up like repeated tries from one spot. Then you document what you find for records or reports. You share details with juniors like you to teach the ropes. It builds better habits all around.
You keep doing these reviews regularly to catch drifts before they grow. I recommend setting reminders so nothing slips through cracks. It keeps things running smooth without big surprises hitting. But you combine it with other checks like account status reviews. Also you watch for spikes in activity that seem off. Perhaps external tools help pull data together easier sometimes. Then you adjust policies if gaps appear during your scans. You learn from each session and refine your approach next time.
You get better at this with practice so stick with it daily.
