“This article shows how to install and run OSSEC HIDS, an open source host-based intrusion detection system. It performs log analysis, integrity checking, rootkit detection, time-based alerting, and active response. It helps you detect attacks, software misuse, policy violations, and other forms of inappropriate activities.”
I’ve been running this on my FreeBSD server for 2 months now, and it’s been fantastic. If I so much as modify one file in /etc I get an email telling me about it. It watches a ton of other things, and is very configurable, but don’t be deterred, it runs fine on the default settings while you learn the system, and install is a snap. While the above HOWTO looks good, I installed w/o any problems from the OSSEC install doc:

I would like to see this project get more attention, as computer security should not end at the firewall or snort.

I like most of the articles in howtoforge, and to be fair they help quite a lot, but i still get the feeling that most [howto’s] are a bit too dumbed down.
In other words, most of the stuff there is targeted at sysadmins who really just can’t follow those steps and be done with it – they MUST RTFM to know the software and setup things the right way.
Still, a great starting point for many people – thanks to all the contributors.
Would be a good practical joke when a cracker broke in and modified the message send to the admin abroad:”Elvis has left the building”.:-)
This looks like a very simple to install protection system – and if it is easy to install then it is likely to be used which is “AGT”.
I wonder how does it compare with installing individual tools to carry out the same tasks? For example I usually install aide, logwatch, logcheck, cron-apt, chkrootkit on Debian machines as these are set up with minimal work.
Maybe ossec is useful for non-debian machines where installing stuff is not as easy and you need to look after many machines?
And the other issue – how would this ossec get updates? The other packages on Debian are of course updated via apt but if ossec gets out of date it may give a false sense of security.
Don’t want to be negative because it looks like a comprehensive and easy to use system – maybe if it was packaged up for Debian it would be near perfect for busy sysadmins.
