VPS Security Hardening: Essential Steps

Published on August 22, 2025

Initial Security Setup

Start with updating your system, creating non-root users, and configuring SSH key authentication. Disable password authentication for enhanced security.

Firewall Configuration

Configure UFW or iptables to allow only necessary ports. Block all unnecessary incoming connections and monitor outgoing traffic.

SSH Hardening

Change default SSH port, disable root login, implement fail2ban, and use strong key pairs. Regular security audits are essential.

Monitoring and Logging

Set up comprehensive logging, implement intrusion detection systems, and monitor system resources for unusual activity.
