Securing or Hardening aims to protect and secure your IT infrastructure against cyberattacks by reducing the attack surface. The attack surface is all the different points where an attacker can to attempt to gain access or damage the equipment. This blog is focused on securing Servers and storage.
The goal of server hardening is to remove all unnecessary components and access in order to maximize security. This is easiest when a server performs a single function. For example, a web server needs to be visible to the internet whereas a database server needs to be more protected. It will often be visible only to the web servers or application servers and not directly connected to the internet.
If a single server is providing multiple functions, there may be a conflict of security requirements. It is best practice not to mix application functions on the same server.
The information below provides a starting point for implementing hardening policies. Some of these only apply to the servers, but others apply to all devices on the network (Servers, Storage, Networking).
