SELinux (Security-Enhanced Linux)

SELinux (Security-Enhanced Linux) is a security feature that strengthens Linux systems by controlling how programs access files and resources. It enforces strict policies to ensure that each process can only perform actions it's explicitly allowed to, reducing risks from bugs or malware. Think of it as a set of detailed security rules that govern who can do what, providing an extra layer of protection without impacting regular system use. This helps organizations protect sensitive data and maintain system integrity against unauthorized access or damage.
