I'm interested in using a Security-centric distro to turn my old HP-Mini Netbook into a kind of router / firewall. I figure I'll still received the network wirelessly and share it through the Ethernet port to my Desktop PC which has not Wifi capability of it's own. One concern I have is from some blog articles I've read saying effective security programs like Snort or Suricata require a few GBs of RAM and my Netbook only has 2 GBs. In the mean time, I'm kind of interested in the Security Onion project or anything that provides a desktop just so I have a simple interface to hookup to Wifi. I'm thinking if this works I might try to buy, over haul, and resell Netbooks as Wifi/Firewalls so I want to keep it kind of simple. If it was just for myself, I might screw around with OpenBSD. Or.... maybe I could install some minimal desktop and install some Linux security programs.
