I’m setting up a Web Application Firewall (WAF) to mitigate Remote File Inclusion (RFI) attacks, but I need help in properly configuring the rules. Specifically, I want to understand:
- How to define custom WAF rules to block RFI payloads effectively.
- Best practices for handling user input validation and filtering.
- How different WAF solutions (ModSecurity, AWS WAF, Cloudflare) handle RFI prevention.
Any configuration examples or rule sets that specifically target RFI attack patterns would be useful.
