Stop Brute-Force Attacks: Fail2ban Setup on Linux (SSH + Nginx)

Learn how to set up Fail2ban to automatically detect and block brute-force attacks on your Linux server — covering both SSH and Nginx in about 10 minutes. In this video, you'll learn how to: ✅ Install Fail2ban on Debian/Ubuntu-based servers ✅ Configure jail.local the right way (never touch jail.conf!) ✅ Set up an SSH jail with maxretry, findtime, and bantime ✅ Whitelist your own IP so you don't lock yourself out ✅ Test bans safely and unban an IP if needed ✅ Build a custom Fail2ban filter to catch Nginx path scanners (404 bots) ✅ Validate your regex with fail2ban-regex before going live Fail2ban turns your server from passively logging brute-force attempts into actively shutting them down — a must-have layer for any Linux server exposed to the internet. 📖 Full written guide: https://vigilnix.com/2026/09/13/stop-brute... 📖 Previous guide (server hardening basics): https://vigilnix.com/2026/08/30/10-things-... 🔗 More Linux security guides: https://vigilnix.com/blog/ #Fail2ban #linux #LinuxSecurity #SSHSecurity #ServerHardening #Nginx #Cybersecurity #LinuxAdmin #DevOps #SysAdmin #BruteForceProtection
