Security-Enhanced Linux (Security-Enhanced Linux)

Security-Enhanced Linux (SELinux) is a security architecture that adds an extra layer of protection to the Linux operating system. It uses mandatory access control, meaning it restricts programs and users to only what they need to function, minimizing the risk of unauthorized access or accidental damage. SELinux enforces strict policies that define how files, processes, and users interact, helping to safeguard sensitive data and systems from potential threats. By controlling these interactions, SELinux enhances the overall security of a Linux system, making it harder for attackers to exploit vulnerabilities.
