> I'm busy securing our LAN and I need to setup a freebsd 4.3 box that will run as firewall and protect my vulnerable network from the internet chaos. I also think of running NAT there too. > > There appear to be quite a lot of hackers and intruders in the wild and I need to keep them out of my lan. > > I'd appreciate any suggestions or links/references to stuff that can help me on this. Although I can't remember any off the top of my head, if you do a search on google for the topic then you'll find a host of resources. Check out www.mostgraveconcern.com/freebsd - I think (althoguh I'm not sure) that they have a tutorial on the issue. > Also, are there any scripts that can be run periodically on a computer and check if there are changes made to files ? Check out tripwire from the ports (/usr/ports/security/tripwire) - in the words of one of my friends a couple of days back "it monitors key system files and goes beserk if anything changes". Not tried it myself, but sounds like what you are looking for. He used a good tutorial for setting up his box actually, to do similar things to you...I'll just see if I can find the address.... http://www.schlacter.dyndns.org/public There you go. Although it seems to be offline at this precise minute, I'd give it another try later. Hope this all helps in some small way.
