What is Azure Web Application Firewall?
Your online apps are centrally protected against typical attacks and vulnerabilities by online Application Firewalls (WAF). Increasingly, hostile attempts that take use of well-known vulnerabilities target web applications. The most frequent attacks are cross-site scripting and SQL injection.

It is difficult to prevent such assaults in application programming. It may necessitate thorough patching, monitoring, and maintenance at several application topology layers. One tool that makes security administration easier is a centralised web application firewall. Additionally, a WAF provides application managers with increased confidence of security against breaches and attacks.
Instead of protecting every single web application, a WAF solution can respond to a security issue more quickly by centrally patching a known vulnerability.
Assisted service
Microsoft’s Azure Application Gateway, Azure Front Door, and Azure Content Delivery Network (CDN) services can be used to deploy WAF. A public preview of WAF on Azure CDN is currently available. Features offered by WAF are tailored to the needs of each individual service. The summary for each service has additional details regarding WAF features.
