01. Introduction
In today’s digital age, cybersecurity has become a critical concern for businesses and individuals alike. As cyberattacks grow more frequent and sophisticated, effective solutions are essential to protect online assets and sensitive information. One such solution is the Web Application Firewall (WAF), a key technology that helps defend against various web-based threats, ensuring the security and availability of web applications.
SafeLine WAF, a leading WAF product, offers powerful protection and intelligent security policies. Today, we’ll dive into the installation process and my experience using SafeLine WAF.
02. Installing SafeLine
The SafeLine WAF Community Edition is free and ideal for personal use, providing a robust security layer for blogs and small websites. The installation process is simple, and with an internet connection, it’s just a single command to complete the setup.
Official Documentation: https://docs.waf.chaitin.com/en/tutorials/install
To install, simply run the following command:
bash -c "$(curl -fsSLk https://waf.chaitin.com/release/latest/setup.sh)"
Once installed, you can access the management interface through port 9443. Configuring the website protection is straightforward—just enter the upstream server details and point your A record to the WAF’s IP address.
03. Basic Protection Configuration
To set up protection:
- Navigate to Protections -> Detection Mod.
- Since I’m running a PHP site, I set high protection for relevant configurations and low protection for unrelated settings. This should slightly improve performance.
You can also check the Attack Events Log to see detailed information about intercepted attacks, tools used, and attack types.
04. Exploring the “Dynamic Protection” Feature
In version 6.0.2, SafeLine introduced the Dynamic Protection feature. This powerful addition dynamically encrypts HTML and JavaScript code each time the site is accessed, making it harder for bots and automated attack scripts to exploit vulnerabilities.
