-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I would recommend a combo of network IDS and host-based IDS: On the network side, you can't go wrong with Snort... somewhat of a learning curve but totally worth it... or you could use something like PortSentry... For Snort: http://www.snort.org For PortSentry: http://www.psionic.com Also, check out Demarc which works with Snort: http://www.demarc.com
For Host Based, I would go with Tripwire or AIDE... Tripwire: http://www.tripwire.org AIDE: http://www.cs.tut.fi/~rammer/aide.html hope that helps... shawn On Sat, 23 Feb 2002, Thomas Madhavan wrote: > Hi all. > > Most of the information on this lists regarding firewalls, sniffers etc seem > to be concerned with LANs, or computers using Ethernet cards. > > I want to set up at least some basic IDS and firewall tools on my box at > home, which isn't on any sort of network. > > Do the same rules apply to me, using a modem?
