How the load balancer handles requests that might pose a security risk to your application.

Example: 

 Vpc vpc;
 ApplicationLoadBalancer lb = ApplicationLoadBalancer.Builder.create(this, "LB")
         .vpc(vpc)
         .internetFacing(true)
         // Whether HTTP/2 is enabled
         .http2Enabled(false)
         // The idle timeout value, in seconds
         .idleTimeout(Duration.seconds(1000))
         // Whether HTTP headers with header fields thatare not valid
         // are removed by the load balancer (true), or routed to targets
         .dropInvalidHeaderFields(true)
         // How the load balancer handles requests that might
         // pose a security risk to your application
         .desyncMitigationMode(DesyncMitigationMode.DEFENSIVE)
         // The type of IP addresses to use.
         .ipAddressType(IpAddressType.IPV4)
         // The duration of client keep-alive connections
         .clientKeepAlive(Duration.seconds(500))
         // Whether cross-zone load balancing is enabled.
         .crossZoneEnabled(true)
         // Whether the load balancer blocks traffic through the Internet Gateway (IGW).
         .denyAllIgwTraffic(false)
         // Whether to preserve host header in the request to the target
         .preserveHostHeader(true)
         // Whether to add the TLS information header to the request
         .xAmznTlsVersionAndCipherSuiteHeaders(true)
         // Whether the X-Forwarded-For header should preserve the source port
         .preserveXffClientPort(true)
         // The processing mode for X-Forwarded-For headers
         .xffHeaderProcessingMode(XffHeaderProcessingMode.APPEND)
         // Whether to allow a load balancer to route requests to targets if it is unable to forward the request to AWS WAF.
         .wafFailOpen(true)
         .build();
