Openwall GNU/*/Linux (Owl) is a security-enhanced server platform that's compatible with other major Linux distributions. Also available in German and Russian, one of Owl's main goals is to "provide a wide range of security tools with Owl, available for use 'out of the box.'" As a result, this platform employs several methods to reduce security issues, incuding: the use of safe defaults, a proactive source code review, and "strong" cryptography within core components.
