Security First
A compromised server can ruin your reputation and business. Security shouldn't be an afterthought. Here is our essential checklist for securing any new Linux VPS deployment.
1. SSH Hardening
Disable root login and password authentication. Use SSH keys instead. Change the default SSH port to reduce scrutiny from automated scanners.
2. Firewall Configuration
Set up UFW (Uncomplicated Firewall) or iptables. Deny all incoming traffic by default and only allow ports you explicitly need (e.g., 80, 443, and your custom SSH port).
3. Fail2Ban
Install and configure Fail2Ban to ban IP addresses that show malicious signs, such as too many failed password attempts. This is a crucial defense against brute-force attacks.
4. Regular Updates
Enable unattended-upgrades to ensure your OS receives critical security patches automatically.
Final Thoughts
Security is a continuous process. Regular audits and staying informed about the latest vulnerabilities are key to keeping your infrastructure safe.
