In computing, hardening is usually the process of securing a system by reducing its surface of vulnerability, which is larger when a system performs more functions,in principle a single-function system is more secure than a multipurpose one. Reducing available ways of attack typically includes changing default passwords, the removal of unnecessary software, unnecessary usernames or logins, and the disabling or removal of unnecessary services.
There are various methods of hardening Unix and Linux systems. This may involve, among other measures, applying a patch to the kernel; closing open network ports; and setting up intrusion-detection systems, firewalls and intrusion-prevention systems.
