Platform(s)

Description

HTTP desync mitigation mode is a feature that helps protect your application against HTTP desync attacks which can cause security vulnerabilities in web applications. The load balancer classifies each request based on its threat level, allows safe requests, and then mitigates risk as specified by the mitigation mode that you specify. The desync mitigation modes are monitor, defensive, and strictest. Application Load Balancers configured with defensive or strictest desync mitigation mode protect your application from security issues that may be caused by HTTP Desync. It was detected that Application Load Balancer {AwsEc2Elbv2} is not configured with defensive or strictest desync mitigation mode.
