A WAF solution can also react to a security threat faster by patching a known vulnerability at a central location versus securing each of individual web applications.
A centralized web application firewall helps make security management much simpler and gives better assurance to application administrators against threats or intrusions. Preventing such attacks in application code can be challenging and may require rigorous maintenance, patching and monitoring at many layers of the application topology. Common among these exploits are SQL injection attacks, cross site scripting attacks to name a few. Web applications are increasingly targets of malicious attacks that exploit common known vulnerabilities. WAF is based on rules from the OWASP (Open Web Application Security Project) core rule sets 3.1 (WAF_v2 only), 3.0, and 2.2.9. Web Application Firewall (WAF) is a service that provides centralized protection of your web applications from common exploits and vulnerabilities. This ensures that the VIP associated with application gateway doesn't change even over the lifetime of the Application Gateway.
The application gateway Standard_v2 SKU supports static VIP type exclusively. Zone redundancyĪ Standard_v2 Application Gateway can span multiple Availability Zones, offering better fault resiliency and removing the need to provision separate Application Gateways in each zone. Autoscaling also removes the requirement to choose a deployment size or instance count during provisioning.įor more information about the Application Gateway Standard_v2 features, see What is Azure Application Gateway v2?. For these applications, application gateway supports end to end SSL/TLS encryption.įor more information, see Overview of SSL termination and end to end SSL with Application Gateway AutoscalingĪpplication Gateway Standard_v2 supports autoscaling and can scale up or down based on changing traffic load patterns. This can be because of security requirements, compliance requirements, or the application may only accept a secure connection. But sometimes unencrypted communication to the servers isn't an acceptable option. This feature allows web servers to be unburdened from costly encryption and decryption overhead. Azure Application Gateway is a web traffic load balancer that enables you to manage traffic to your web applications.Īpplication Gateway includes the following features: Secure Sockets Layer (SSL/TLS) terminationĪpplication gateway supports SSL/TLS termination at the gateway, after which traffic typically flows unencrypted to the backend servers.
