automated nids doesn't make any sense on a small scale
generating a statistical overview is good enough
just look at it yourself
a list of all ips will give enough insight to notice anything being wrong
No.44
have something that also logs the processes associated with the ips on the server that might get intruded
that can also make it very obvious something went wrong if an unknown process starts making connections
