Sorry, but good intrusion detection is very different to iptables.
Iptables only control the connections based on ports. With connection
tracking you can check if there is made some portscan or someone tried
to send a ping of death to you.
Modifying in the filesystem can not be controled by iptables. That is
task of a good intrusion detection system.
