Security log is full

Sometime I log in my computer, there is an message that my security log is full and only the administrator can clear it.

What does that mean and how do I clear it as an admistrator?

under computer management - event viewer - choose your log and select properties

you shoul dhave it set to overwrite as needed but you can manually clear from there as well

I don't see what version of Windows you are running, but the following link is an idea how to tweak your logging events to capture real security events:

Also, you can manually delete the log files by going to:
Start-->Settings-->Control Panel-->Administrative Tools--Event Viewer
Right mouse over "Security Log"
Select "Clear All Events"
Say "No" to saving it

Now the log is not full.

If you security log is filling up, you need to figure out WHY by reviewing the types of activities you are monitoring.

If needed, you can increase the maximum size of the log (recommended) or reduce what you are watching for (probably not a good idea).

I would strongly recommend against "Overwrite as needed". Different kinds of attacks can fill up a log pretty quickly and your evidence of the attack will be 'overwritten'.

We use a fairly large maximum (about 20 MB) and NEVER 'overwrite'. If one of our security logs gets filled up, we want an Administrator to figure out why.

Security Administrators tend to be a little paranoid - with good reason.

Good Luck,
