Episode 98 — Server OS Hardening — Patches, Ports, and Service Reduction

Certified - CompTIA Server+ Audio Course

This episode focuses on securing a server operating system by applying hardening techniques that minimize vulnerabilities. We cover the importance of keeping systems fully patched, closing unused network ports, and disabling unneeded services. The discussion also includes reviewing startup processes, removing default accounts, and enforcing secure configurations for network protocols.

We provide real-world and exam-oriented examples, such as reducing the attack surface of a web server by disabling unused modules or applying OS security baselines before deployment. Troubleshooting topics include verifying patch compatibility, confirming firewall rules, and monitoring for unauthorized services. Mastering OS hardening practices ensures candidates can maintain secure, stable systems resistant to common attack methods.
