operating system A version of
BSD Unix with an emphasis on security. A lot of security work that is ported to other free operating systems originates with OpenBSD and a lot of code review is done here.
Sub-projects of OpenBSD include implementations of SSH (https://openssh.org/), ntpd (https://openntpd.org/), and
CVS, to be called OpenCVS.
