Adversaries may target resource intensive features of web applications to cause a denial of service (DoS). Specific features in web applications may be highly resource intensive. Repeated requests to those features may be able to exhaust system resources and deny access to the application or the server itself. (Citation: Arbor AnnualDoSreport Jan 2018)

Comments
The "elb-cross-zone-load-balancing-enabled" managed rule can verify that load balancing is properly configured, which can mitigate adversaries' ability to perform Denial of Service (DoS) attacks and impact resource availability. "cloudfront-origin-failover-enabled" can verify that failover policies are in place to increase CloudFront content availability.
Coverage factor is minimal for these rules, since they are specific to a subset of the available AWS services, resulting in an overall score of Minimal.

Comments
VPC security groups and network access control lists (NACLs) can be used to restrict access to endpoints but will prove effective at mitigating only low-end DOS attacks resulting in a Minimal score.

Comments
AWS Network Firewall has the ability to pass, drop, or alert on traffic based on the network protocol as well as perform deep packet inspection on the payload. This functionality can be used to block adversaries from carrying out denial of service attacks by implementing restrictions on which IP addresses and domains can access the resources (e.g., allow lists) as well as which protocol traffic is permitted. That is, the AWS Network Firewall could block the source of the denial of service attack. This mapping is given a score of Partial because the source of the attack would have to be known before rules could be put in place to protect against it.
