Damn Vulnerable Linux (DVL) is everything a good Linux distribution isn’t. Its developers have spent hours stuffing it with broken, ill-configured, outdated, and exploitable software that makes it vulnerable to attacks. DVL isn’t built to run on your desktop - it’s a learning tool for security students.

“Many users have implemented Secure Shell (ssh) to provide protected access to a remote Linux system, but don’t realize that by allowing password authentication, they are still open to brute-force attacks from anywhere on the Internet.”
