Firewall (WAF) comes in.Introduction to WAFA WAF is a web application firewall that helps protect your web applications. Think of it like the specialized commando unit of your network security, specifically trained to protect your web applications and websites from threats that conventional network firewalls might miss. WAFs are particularly good at protecting against application layer attacks.The Difference Between a Regular Firewall and a WAFA conventional firewall and a WAF differ in the type of traffic they monitor and protect. A traditional firewall, such as pfSense CE, primarily focuses on protecting network traffic at the transport layer, while a WAF concentrates on HTTP/HTTPS traffic at the application layer.So, while a regular firewall checks if the delivery truck (packet) coming to your warehouse (network) is on the approved list, a WAF checks what’s inside the truck (inspects the data) to ensure it’s not carrying anything harmful.Discussing How a WAF Works and Where It is Placed in a NetworkJust as an airport uses both metal detectors and luggage scanners for security, a comprehensive network security approach uses both firewalls and WAFs.A WAF is generally placed in front of your web applications, acting as a protective shield. It examines web traffic and uses rules (often known as web security rules) to filter out malicious activity such as Cross-Site Scripting (XSS), SQL Injection, and DDoS attacks.AWS WAF is a web application firewall that helps protect your web applications running on AWS, but you can also set up a WAF using the open-source pfSense software on your own hardware.The WAF functions like a cyber traffic cop, directing the flow of data between your web applications and the external network. By using content filtering, it can block, allow, or redirect web traffic based on predefined security policies. It’s like a specialized bouncer for your web applications,
