"Learning about Trinux will give you instant fame and riches, right? Well, not exactly, but it can offer a compact security solution for your PC. This unique distribution of Linux boots from one or two floppies and inhabits only RAM. Think of it as a slimmed-down Linux, which is small enough to avoid install hassles on your PC's hard drive, but will still give you considerable security power. Trinux may not make one rich, but it may help protect one's treasures."

"An open source product released under GNU's Public License, Trinux addresses security problems such as packet sniffing, sniffer detection, and intrusion detection. Trinux also comes with utilities containing strong cryptography such as OpenSSL and Open SSH."

"The Trinux OS ships with packet analysis tools such as tcpdump and the console version of Ethereal. These tools allow an inside look at what's going on with traffic on your network. Nmap, also included in the Trinux implementation, allows the user to probe for vulnerable ports and inappropriate services. It uncovers potential exploits of FTP, IMAP, POP, DNS, and HTTP. And, as Michael H. Warfield comments in his article, "Securing Linux,"
