Red Hat Enterprise Linux 7 Security Guide

I’d like to share a great free resource published by Red Hat that covers essential Linux server security configurations.

Although the guide was originally written for RHEL 7, most of its content remains fully relevant and compatible with RHEL 9 (and possibly RHEL 10, though I haven’t yet reviewed that version).

• Basic but essential Linux server security hardening step
• Configurations that meet general-purpose requirements for a simple, secure server
• Practical guidance for administrators who want to ensure their systems are not left with default vulnerabilities

This is not just a “checklist”, it provides explanations and reasoning behind the settings, which makes it a useful reference for both new system administrators and experienced professionals looking to confirm best practices.

If you’re running RHEL (or CentOS/AlmaLinux/Rocky Linux derivatives), this guide is a solid foundation for your security setup.
