Moving SSH from port 22 to a non-standard port can eliminate up to 99% of automated scans. 3. Identity and Access Management
Follow the principle of least privilege to limit what users and services can do. Linux Server Hardening
Run system updates immediately upon setup (e.g., apt update && apt upgrade for Debian/Ubuntu or dnf update for RHEL/Fedora). Moving SSH from port 22 to a non-standard
Securing the primary remote entry point is vital for stopping automated brute-force attacks. Run system updates immediately upon setup (e
Below is a structured write-up covering the essential stages of a Linux hardening project. 1. Update and Patch Management
Configure automatic security updates using tools like unattended-upgrades on Debian/Ubuntu or dnf-automatic on RHEL/Fedora. 2. Secure Access (SSH Hardening)
Linux server hardening is the process of reducing a system's attack surface to protect against unauthorized access and data breaches. A default Linux installation is often a "blank canvas" rather than a fortress; hardening provides the necessary reinforcement.
