Security-Enhanced Linux is known as SELinux. It adds an extra layer of security policies to a standard Linux system.
It is an open-source operating system kernel. It is mostly used for its flexibility and stability.
SELinux enforces mandatory access controls, while standard Linux uses discretionary access controls.
SELinux provides fine-grained security policies, restricting access even for root users.
SELinux can slightly impact system performance due to additional security checks.
SELinux is ideal for environments requiring high security, such as servers and sensitive data systems.
