I looked at one of the systems at work today. When I logged in, it said that the security log was full. Logging was enabled for "successful" events. What I saw was that in addition to logging users who had logged in...it also logged a number of "anonymous logins".
I almost got sick....but there's got to be an explanation. What generates an "anonymous login"?
This machine is not exposed to the internet and does not host a web site. I wished I would have saved the log...but was in a hurry to get it back up.
Same as it ever was...Same as it ever was
