Exam DCA topic 1 question 3 discussion

SELinux (Security-Enhanced Linux) is a security mechanism that enforces access control policies. However, SELinux is not responsible for blocking the ability to set the system time from inside a Docker container. The actual reason for this restriction lies in Docker’s default isolation mechanisms and Linux capabilities. * Docker’s Security Model: • Docker containers operate in a sandboxed environment and lack access to host-level kernel features, including system-wide time changes. • This restriction is in place to prevent containers from interfering with the host system or other containers.

SELinux (Security-Enhanced Linux) could potentially block a user's attempts to set the system time from inside a Docker container. SELinux is a security feature that provides mandatory access control policies, and it can restrict certain system operations, including actions taken within a container.
