Question

What is selinux

Accepted Answer

SELinux (Security-Enhanced Linux) is a security module for the Linux kernel that provides access control security policies.

SELinux is a mandatory access control (MAC) system implemented in the Linux kernel.
It provides fine-grained access control policies, allowing administrators to define rules for how processes and users can interact with files, directories, and other system resources.
SELinux policies are defined in a set of rules called security contexts, which specify the permissions and restrictions for different types of objects.
SELinux can help prevent privilege escalation attacks and limit the damage that can be caused by compromised processes.
Examples of SELinux commands include 'semanage' for managing SELinux policy, 'setenforce' for changing the enforcement mode, and 'getenforce' for checking the current enforcement status.
