Web Application Firewall
Understanding Web Application Firewalls
A Web Application Firewall (WAF) is a vital layer of defense that protects web applications from a wide range of cyber threats. By filtering and monitoring HTTP/HTTPS traffic, WAFs detect and block attacks like SQL injection, cross-site scripting (XSS), and DDoS. Unlike traditional firewalls that operate at the network layer, WAFs focus on application-level security, ensuring that malicious data never reaches your application servers.
WAFs can be deployed as hardware appliances, cloud-based solutions, or integrated with content delivery networks (CDNs). They protect against data breaches, fraud, and downtime by inspecting web traffic, enforcing custom rules, and mitigating malicious requests in real-time. With businesses relying heavily on web applications, a WAF is an essential part of any modern cybersecurity architecture.
