SELinux

SELinux, or Security-Enhanced Linux, is a security feature integrated into Linux systems. It restricts how processes can interact, ensuring that programs have only the permissions they need to function. This limits the potential damage from security breaches, as even if a hacker gains access to a program, they can't easily manipulate other parts of the system. SELinux operates using policies that define what actions are allowed and denied, enhancing the overall security and stability of the operating system. It’s a vital tool for protecting sensitive data and maintaining system integrity against various threats.
