Since 1995, OpenBSD has been developed around the principle of 'secure by default'. Continuous code audits, privilege separation, and proactive security features define its architecture.

The OpenBSD installer guides you through partitioning, set selection, and basic system configuration. Signed release images guarantee authenticity through SHA256 and signify verification.
Categories: Fundamentals OpenBSD
OpenBSD systems are configured through text files. hostname.if controls network interfaces, ntpd synchronizes the system clock, doas provides delegated root privileges, and sysctl adjusts kernel parameters.
Categories: Fundamentals Package Management
OpenBSD strictly separates the base system and packages. pkg_add installs software from signed repositories, pkg_delete cleanly removes packages, and pkg_info lists installed software.
Categories: Fundamentals Security
OpenBSD implements security through privilege separation, pledge(), unveil(), W^X memory protection, and proactive code audits. Securelevels restrict root privileges, and LibreSSL replaces OpenSSL.
