OS Change Management Auditing using Nagios?

We use AIDE for some systems here; it's included with recent Red Hat
distributions (and possibly others) and can be compiled for pretty much
any other *nix platform.  My ISO is quite keen on it.

 

Cheers

Thanks, Kevin.

 

You do raise a valid point about knowing what is changing in the general
updates vs what is un-authorized and knowing the difference. My,
possibly naive, thought is that I could batch updates/patches and make
the assumption the changes are due to that process, but there is that
chance something changes in that period as well..... If nothing else,
changes at 2am or off hours would hopefully raise an alarm to be
investigated.

 

I'll take a look at Tripwire in more depth (I glanced at it briefly and
wasn't sure if it was too involved for what I was looking for or not) as
well as open-audit.


Thanks.

Ken

there is a way to have changes in OA propagate to Nagios.

Another tool you may want to look into is tripwire; it generates exactly
the logs based on changes that you were looking for. Then use the
check_log plugin to monitor the tripwire log file.

The biggest concern with this type of tool that I would have is that
monitoring OS changes is very labor-intensive. For me, to the point of
impracticality. The problem is the sheer volume of patches that come out
on a regular basis makes it all but impossible to keep up with. You'd
have to look at every single patch and find out which files it changes
before you have a way of knowing whether a particular tripwire alert is
legitimate or not.
