Firewalls Questions
The role of firewalls in protecting against web application attacks is to act as a barrier between the internet and the internal network, monitoring and controlling incoming and outgoing network traffic. Firewalls analyze the data packets and enforce security policies to block or allow specific types of traffic based on predefined rules. They can inspect the content of the packets, filter out malicious or suspicious requests, and prevent unauthorized access to web applications. Firewalls also help in detecting and blocking common web application attacks such as SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF).
