Web Application Firewall

Definition

A Web Application Firewall (WAF) is a security solution that monitors, filters, and blocks HTTP traffic to and from a web application, including those interacting with blockchain services. It protects against common web vulnerabilities like SQL injection, cross-site scripting, and denial-of-service attacks, which could compromise user interfaces or data access. The WAF acts as a protective shield between users and the web application. It enhances the security posture of digital asset platforms.
