HardenedBSD is a security-focused operating system, derived from the FreeBSD operating system. It is designed to provide enhanced security and protection against exploit attacks. HardenedBSD implements a variety of security features, including application sandboxing, privilege separation, security-enhanced Linux (SELinux)-like Mandatory Access Control (MAC) and Address Space Layout Randomization (ASLR). It also includes various security tools and services, such as a secure shell (SSH) daemon, a secure FTP (SFTP) daemon and a secure web server. HardenedBSD also offers a number of security hardening features to make the system more resistant to attack, such as kernel-level protection against buffer overflow attacks, and enhanced security for network applications. Finally, HardenedBSD provides an extensive set of security audit tools to ensure that the system remains secure and compliant with security policies.
