It involves kernel patching, changing default ports to more secure one, removal of unnecessary package or only installing of necessary packages, changing password to more secure one, setting up firewalls/intrusion-detection Whether you use the built-in Windows performance monitor, or a third party solution that uses a client or SNMP to gather data, you need to be gathering performance info on every server. The Importance Of Server Hardening . When considering server hardening, remember the applications that will run on the server and not just the operating system. Read this post to learn how to defend yourself against this powerful threat. These can be attractive targets for exploits. Building new servers to meet that ideal takes it a step further.
