OpenBSD is a Unix operating system, based on the BSD (Berkley Software Distribution), developed by Theo de Raadt since 1995.[1] The first version of OpenBSD (1.2) released on July 1996.[1]
The OpenBSD project produces a free, multi-platform BSD 4.4-based Unix operating system. Its efforts emphasize portability, standardisation, correctness, proactive security and integrated cryptography. The project also develops the widely-used and popular OpenSSH (OpenBSD Secure Shell) software, which provides encrypted communication sessions over a computer network using the SSH protocol.[2]
Many open source projects widely used in other operating systems started off as components of OpenBSD, such as doas, a safer replacement of the popular sudo, the aforementioned OpenSSH and Xenocara, a customized X.Org build infrastructure.[1]
Like all BSD operating systems, OpenBSD provides a kernel, drivers, userland utilities and documentation unlike Linux, which provides just the kernel and drivers, relying on third-parties such as GNU.
