They can also provide additional security features, such as encryption and authentication.
WAFs use a variety of techniques to detect and prevent attacks, such as signature-based detection, anomaly detection, and behavioral analysis. They can be configured to allow only specific types of traffic to reach the web application, based on various criteria such as IP address, user agent, and other request attributes. WAFs are deployed in front of web servers or applications, analyzing all incoming HTTP/HTTPS traffic and blocking any requests that match predefined security rules. The WAF sits in front of this layer as an extra shield to scrutinize the traffic and protect it from various threats.A Web Application Firewall (WAF) is a security tool that provides protection for web applications against a variety of attacks, such as SQL injection, cross-site scripting, and other common vulnerabilities. Whenever a client makes a request, it first reaches this layer. This is the top layer of data processing of the Open Systems Interconnection (OSI) Model and directly interacts with clients. While a vulnerability scanner points out the holes in security defenses, a web application firewall makes sure a hacker can’t exploit those vulnerabilities.Ī web application firewall provides application-layer security. It continuously monitors the web traffic coming to your web application and blocks anything suspicious.Ī WAF protects the servers from attacks such as:Ī WAF also prevents data from leaking from the server. The web application firewall works like a shield that’s placed between a website server and the internet. What Is a Web Application Firewall? WAFs ExplainedĪ WAF is a type of security software or hardware component that filters HTTP/S traffic coming from clients in order to protect a server from malicious traffic.
