Protect Your Cloud Server from Brute Force Attacks Using Fail2Ban

Let’s start with the basics.

What is a Brute Force Attack?

A brute force attack is a common hacking technique where automated scripts try thousands of username and password combinations until they gain access. These attacks often target cloud servers with exposed services like SSH, FTP, or web login portals, putting your data and resources at serious risk.

How Fail2Ban Helps

Fail2Ban is a powerful, open-source intrusion prevention tool that protects your server by monitoring log files and automatically banning IP addresses showing signs of malicious behavior—like repeated failed login attempts. It’s widely used on Linux-based cloud servers to guard against brute-force attacks and unauthorized access.

Key Features of Fail2Ban:

• Blocks suspicious IPs in real-time
• Prevents brute-force login attempts across multiple services
• Reduces server load by filtering out malicious traffic
• Highly configurable with custom ban rules and timeouts
