ok, One of our web servers got hacked this morning. A quick restore of the backup resolved the issue. They where able to get in because this server was not up2date. However, I want to be able to monitor/view attempts. I'm sure this is not the first time and I've never really worried about it much. Now I want to keep a very close eye on things. Our environment is mixed with windows/linux. What would you all suggest I could use to monitor all the servers?
