Wroking of WAF,Active and Passive model.

Question

Accepted Answer

WAF stands for Web Application Firewall. It can operate in active or passive mode to protect web applications from attacks.

WAF is a security solution that monitors, filters, and blocks HTTP traffic to and from a web application.
In active mode, WAF actively inspects and filters traffic in real-time, blocking malicious requests before they reach the web application.
In passive mode, WAF monitors traffic but does not actively block anything. It provides alerts and reports for analysis.
Active mode offers real-time protection but may cause false positives. Passive mode is less intrusive but may not prevent attacks.
Examples of WAF solutions include ModSecurity, Cloudflare WAF, and Barracuda Web Application Firewall.
