Web Application Firewalls (WAFs)

How does a Web Application Firewall (WAF) protect against SQL injection attacks?

A Web Application Firewall (WAF) protects against SQL injection attacks by inspecting incoming web traffic and filtering out any malicious SQL queries that could exploit vulnerabilities in the web application. By analyzing the HTTP requests and responses, the WAF can detect and block any suspicious SQL injection attempts, thus preventing unauthorized access to the database and protecting sensitive data from being compromised.

A WAF can effectively mitigate cross-site scripting (XSS) vulnerabilities in web applications by inspecting the web traffic for malicious scripts that could be injected into the web pages. The WAF can detect and block any XSS attacks by sanitizing the input data and encoding the output to prevent the execution of malicious scripts in the user's browser. This helps in protecting users from being exposed to harmful scripts that could steal sensitive information or perform unauthorized actions on the website.
