Need IDS if using IPtables/Firewall??
I have got my Slack 10 install on the net, running fine on dial-up right now, and am using Firestarter as a firewall front end. I am also using chkrootkit as the second leg in my security stance.
My question is: Do I actually need to use an intrusion detection utility like snort, or a file integrity checker like tripwire, in addition to these first steps??
I want to have a fairly secure system, but I am not overly paranoid unless someone here convinces me to be otherwise.
If I have have any obvious misperceptions please correct me, I am a Linux newcomer, and don't really know much of what I am talking about here.
Thank you, Head
