GSL LOGIC

ElastiCache should not have engine='memcached'

REMEDIATION

From Portal
The AWS PCI DSS Compliance program only includes Amazon ElastiCache for Redis as a PCI-compliant service. So it is recommended not to use memcached engines. Use below steps from AWS console to validate Memcached is not used in AWS PCI DSS environments.

For each PCI-DSS environment, login to AWS console.
Go to Amazon ElastiCache service: https://us-east-1.console.aws.amazon.com/elasticache.
In the left navigation panel, click on 'Memcached clusters' and validate if there is no cluster created/used in that PCI-DSS environment.

From Command Line
Use below command to ensure there is no Memcached cluster available in your PCI-DSS environment.

aws elasticache describe-cache-clusters
