HIPAA Security - Implement elb-cross-zone-load-balancing-enabled config rule

[dontirun]

Summary

As a developer

I would like to implement the elb-cross-zone-load-balancing-enabled config rule

So that I can check if qualified resources in my CDK app conforms to the following HIPAA Security control(s): 164.308(a)(7)(i), 164.308(a)(7)(ii)(C)

Details

ruleId: HIPAA.Security-ELBCrossZoneLoadBalancingEnabled

info: The Elastic�Load�Balancer does not have cross-zone load balancing enabled - (Control IDs: 164.308(a)(7)(i), 164.308(a)(7)(ii)(C))

Given Reason: Enable cross-zone load balancing for your Elastic Load Balancers (ELBs) to help maintain adequate capacity and availability. The cross-zone load balancing reduces the need to maintain equivalent numbers of instances in each enabled availability zone. It also improves your application's ability to handle the loss of one or more instances.

Acceptance Criteria

If the rule can be implemented

Given a CDK app with a non-compliant resource

• When HIPAA Security Pack is enabled
• Then the CDK stack does not deploy and the user receives an ERROR with relevant Control ID information about the non compliant resource

Given a CDK app with a compliant resource

• When HIPAA Security Pack is enabled
• Then the CDK stack deploys and the user does not receive an ERROR about the compliant resource

Given the cdk-nag RULES file

• When the HIPAA.Security-ELBCrossZoneLoadBalancingEnabled rule is added to the rule pack
• Then the HIPAA Security Errors section is updated with the rule information

If the rule cannot be implemented

Given the cdk-nag RULES file

• When the elb-cross-zone-load-balancing-enabled check is not added to the rule pack
• Then the HIPAA Security Excluded Rules section is updated with the check information
