The WAF protects from your common web based exploits. The WAF SKU is a Standard SKU, providing all the rich features of a layer 7 load balancer, but now also serves as a web application firewall. For this article, we will focus on the latter. The Azure Application Gateway is a layer 7 load balancer with two SKUs to distinguish between Standard and Web Application Firewall. Let’s take a look at the Azure Application Gateway (WAF), and see how it can be a part of our toolset for protecting our web applications. External threats are scanning public IP ranges to find known vulnerabilities and exploit businesses.
For more information about WAF features for each service, see the overview for each service. WAF has features that are customized for each specific service. WAF on Azure CDN is currently under public preview. WAF can be deployed with Azure Application Gateway, Azure Front Door, and Azure Content Delivery Network (CDN) service from Microsoft. A WAF also gives application administrators better assurance of protection against threats and intrusions.Ī WAF solution can react to a security threat faster by centrally patching a known vulnerability, instead of securing each individual web application. A centralized web application firewall helps make security management much simpler. It can require rigorous maintenance, patching, and monitoring at multiple layers of the application topology.
Preventing such attacks in application code is challenging.
