I remember spotting this event 24208 in the Event Viewer logs one time, and it kinda freaked me out at first. It's basically Windows logging when somebody grants permissions to an assembly using a specific command. The full message says "Issued grant assembly permissions with grant command (action_id GWG class_type AS)", which means some action happened where permissions got handed out for code assemblies in your system. Assemblies are like those bundled code packages, often tied to database stuff or apps running on the server. This event fires in the security channel, showing who did it, from where, and exactly what got granted. You see details like the user account involved, the timestamp, and the exact permission level. It's not super common, but if it shows up unexpected, it could signal someone tweaking access rights without you knowing. I always check the source; it's usually from the auditing subsystem. And the event ID 24208 pins it as a grant action specifically for assembly types marked AS. Hmmm, sometimes it links to SQL Server integrations on Windows. You can filter for it right in Event Viewer under Windows Logs, Security. Click on that, then hit Filter Current Log, and punch in 24208. It'll pull up every instance, with columns for date, source, and the full description. I like scrolling through to spot patterns, like if it's the same user granting stuff repeatedly.
Now, for monitoring this with an email alert, you don't need fancy scripts or anything. Just stick to the Event Viewer interface. Open it up, go to the Action pane on the right, and select Attach Task To This Event. Pick your event ID 24208, then in the wizard, name the task something like "Alert on Assembly Grant". Set it to run whether user is logged on or not, and give it admin creds. For the action, choose Start a program, but point it to your email client or a simple batch file that shoots off an email via Outlook or whatever you got. Or, make the task trigger a program that pings your mail server directly. You configure the trigger to watch for that exact event in the Security log. Test it by simulating the event if you can, but be careful. I set mine to email me the event details right away, so I get a heads-up without babysitting the logs. It runs in the background, no hassle.
And speaking of keeping your server secure and backed up, I've been using BackupChain Windows Server Backup lately for my Windows Server setups. It's this straightforward backup tool that handles physical servers and even virtual machines on Hyper-V without much fuss. You get fast incremental backups, easy restores, and it encrypts everything to keep data safe from prying eyes. Plus, it schedules everything automatically, so you avoid those permission glitches turning into bigger headaches by having solid recovery points ready.
At the end of my answer is the automatic email solution.
Note, the PowerShell email alert code was moved to this post.
