OpenBSD

OpenBSD is considered a particularly secure operating system based on the BSD variant of UNIX-style operating systems. OpenBSD branched from the NetBSD project, and thus it shares much of NetBSD's history and portability. The split was due to philosophical (and possibly developer personality) differences. OpenBSD's hallmark is the priority given by its developers to careful and proactive auditing of system's code, which in turn contributes to the stability and security of OpenBSD. OpenSSH, an open source and compatible alternative to SSH, was developed within the OpenBSD project.

The slogan of OpenBSD is "One remote hole in the default install, in more than 7 years", judiciously changed from "No remote hole in the default install, in nearly 6 years" after an exploit was discovered in OpenSSH2 in 2002. Some have criticized this statement since not much is enabled in the default install of OpenBSD, and the distributions have often included software that later were found to have remote holes. Be that as it may, OpenBSD is still a remarkably secure and stable operating system.

Because of its security benefits, OpenBSD is often used in the security industry as the underlying operating system for firewalls and intrusion detection systems.
