Last September at Ignite we announced plans for better web application security by adding Web Application Firewall to our layer 7 Azure Application Gateway service. We are now announcing the General Availability of Web Application Firewall in all Azure public regions.
Web applications are increasingly targets of malicious attacks that exploit common known vulnerabilities, such as SQL injection and cross site scripting attacks. Preventing such exploits in the application requires rigorous maintenance, patching, and monitoring at multiple layers of the application topology. A centralized web application firewall (WAF) protects against web attacks and simplifies security management without requiring any application changes. Application and compliance administrators get better assurance against threats and intrusions.
