Linux

Enforcing security in Linux involves implementing measures that protect the system from unauthorized access and vulnerabilities. This can include setting permissions for files and directories, employing security modules like SELinux or AppArmor to enforce mandatory access controls, and regularly applying updates to address security vulnerabilities. Additionally, configuring firewalls and intrusion detection systems helps to monitor and control network traffic, enhancing overall system security. These measures collectively ensure the integrity, confidentiality, and availability of system resources.
