Web application firewall (WAF)
A Web Application Firewall (WAF) is a security system designed to protect websites from cyber threats and attacks. It acts as a barrier between the internet and a web application, filtering and monitoring incoming traffic. By analyzing data for harmful activity, it helps block malicious requests, like attempts to exploit vulnerabilities or steal data. WAFs are crucial for ensuring a website remains safe from common threats such as cross-site scripting or SQL injection, thus providing a layer of defense that keeps both the site and its users secure.

A Web Application Firewall (WAF) is a security tool designed to protect web applications from various online threats. Think of it as a virtual barrier that monitors and filters incoming traffic to a website. It helps detect and block malicious activities, like hacking attempts or data breaches, before they reach the application. By analyzing HTTP requests, a WAF can identify suspicious patterns and enforce security rules, ensuring that only safe and legitimate users can access the website. Essentially, it safeguards sensitive information and helps maintain the integrity of online services.
