8G Firewall

Overview

The 8G Firewall is a powerful security feature that protects your website from malicious HTTP requests, SQL injection attacks, XSS (Cross-Site Scripting), and other common web vulnerabilities. It's based on the Perishable Press 8G Firewall ruleset.

This feature is available for sites running on both Nginx and Apache web servers.

What Does 8G Firewall Protect Against?

The 8G Firewall filters malicious requests at the web server level, blocking:

• Malicious Query Strings: SQL injection attempts, base64 encoding attacks, and suspicious parameters
• Unsafe Request Methods: Blocks TRACE, DELETE, and TRACK methods that shouldn't be used by normal visitors
• Malicious Referrers: Blocks requests from known bad referrer domains
• Suspicious Request URIs: Prevents access to configuration files, backup files, and system directories
• Malicious User Agents: Blocks known malicious bots and scrapers

How to Enable 8G Firewall

1. Navigate to your site details page
2. Click on the Utilities section
3. Find 8G Firewall in the list
4. Click on the 8G Firewall option
5. In the dialog that appears, click the Enable button
6. Wait for the job to complete

Once enabled, the firewall rules will be automatically applied to your site's web server configuration.

How to Disable 8G Firewall

Important Notes

• The firewall rules are applied at the web server level, providing fast and efficient protection
• The firewall uses HTTP 403 Forbidden responses to block malicious requests
• Legitimate traffic is not affected by these rules

Troubleshooting

False Positives

In rare cases, the 8G Firewall might block legitimate requests. If you experience issues after enabling the firewall:

1. Check your web server error logs
2. Look for 403 Forbidden responses
3. If you find false positives, you can disable the firewall temporarily
