1.) Tool must be freely available, and free for personal use.
2.) When posting info on tools, please include the Operating System in the title of the post, such as "Windows IDS Tools", or "Linux Firewall Tools"
I just recently switched to a *nix platform and do not know what apps are any good, but I did notice that people are not posting what OS's these apps are for.
Just mentioning it since it was posted.

Operating System Mandrake Linux

Firewall: Shorewall. If there is better free one, let me know!

Anti-Virus: BitDefender. I was told antivirus was not needed for Linux.

Stay Updated!
