Locked Down Out of the Box

Favorable review of EnGarde Secure Linux, despite no mention of the Mandatory Access Control it employs. "Although these efforts have gone a long way toward improving the security of Linux, most mainstream vendors still don't address the needs of those who require a high level of security or need a bulletproof server at installation time. Enter security-enhanced distributions. Of the many vendors offering this type of secure solution, two offerings, Engarde Secure Linux and Immunix, caught our favor as the most polished and ready for prime time.
EnGarde Secure Linux (ESL; www.engardelinux.org) is administrated completely over a Web-based user interface. ESL was developed by Guardian Digital for use on its rack-mountable server appliances. In keeping with the tradition of open source and the GPL (GNU Public License), Guardian Digital is releasing the entire distribution to the public, making it available for download from the company's site.
