ElastiCache should not have engine='memcached'

  1. For each PCI-DSS environment, login to AWS console.
  2. Go to Amazon ElastiCache service: https://us-east-1.console.aws.amazon.com/elasticache.
  3. 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.
