Hardening server security

Most of us assume that systems or servers are already secure, and this might be a false assumption. Imagine if any system server, firewall or router is stolen without first being hardened. An attacker would probably first try to crack a targeted system with a default username and password. For a Linux based machine, my default username would be root, the password would be root, and most of us would continue to use it. Server hardening involves identifying and re-mediating security vulnerabilities. We will discuss server hardening and the best practices you can implement immediately in order to reduce the risk of attackers compromising your business's critical systems and data.
