SEC does seem to be the "gold standard" in advanced log correlation beyond
that available in "grep | mail" type systems such as logwatch. However it
is incredibly arcane, and despite reading a lot of documentation for it I've
never really been able to wrap my head around it.
A colleague has started to write a SEC-like tool with (I hope) a more
approachable mental model; take a look at http://github.com/rodjek/grok. I
must (embarrasedly) admit I haven't looked at it yet, but he claims that he
reimplemented sshd_sentry (the fail2ban equivalent we use) in two lines of
rules, which seems like a nice (basic) demonstration.
