Using Linux Live CD Security Tools
If you suspect your computers or networks have been exploited, a wide range of security tools is
available for Linux that you can use to scan for viruses, do forensics, or monitor activities of intruders.
The best way to learn about and use many of these tools is by using dedicated, bootable Linux
distributions built specifically for security.
Advantages of Security Live CDs
One great advantage of using a live CD or DVD to check the security of a system is that it separates
the tools you use to check a system from the system itself. In other words, because the tools for finding
problems on an installed system may themselves be compromised, a live CD of trusted software
can be a good way to ensure that you are testing a potentially infected system with clean tools.
If, despite your best efforts (good passwords, firewalls, checking log files, and so on), you believe
an intruder may have gained control of your system, you can use a live CD to check it out. Security
live CDs such as System Rescue CD, INSERT, and BackTrack (all included on this book??™s CD or
DVD) are great tools for checking and fixing your system.
