EnGarde Secure Linux

EnGarde Secure Linux was an open source server-only Linux distribution developed by Guardian Digital. EnGarde incorporates open source tools such as Postfix, BIND, and the LAMP stack.

The platform includes services for web hosting, DNS and email, and others. Since 2005, SELinux has been incorporated into the platform by default. Other security services are included by default as well, such as intrusion detection, anti-virus, network management and auditing and reporting tools.

Users can configure the services through the command line, or remotely manage them through WebTool, the platform's browser-based interface.

Overview of history and development

Since its inception in 2001, the platform has been developed as an OS that incorporates only server functionality while focusing on security as the priority. Originally, the platform loosely drew on some of the code from early versions of Red Hat Linux. Within less than a year of development, much of that was re-engineered. Since then EnGarde has been treated as its own platform, as it maintains its own package repository based on RPM, among other changes.
