### Description{% #description %}

ElastiCache Redis engine versions must meet the AWS PCI DSS baseline. Running outdated Redis releases can expose known vulnerabilities and lead to non-compliance. In Ansible, tasks using the `community.aws.elasticache` or `elasticache` modules must define `cache_engine_version` and set it to a version equal to or newer than `4.0.10`. Resources missing `cache_engine_version` or specifying a lower version are flagged as non-compliant. Update to a maintained Redis release that satisfies PCI DSS requirements.

Secure example for Ansible:

```yaml
- name: Create ElastiCache Redis cluster
  community.aws.elasticache:
    name: my-redis-cluster
    engine: redis
    cache_engine_version: "4.0.10"
    node_type: cache.t3.small
    num_cache_nodes: 1
```

## Compliant Code Examples{% #compliant-code-examples %}

```yaml
- name: Basic example
  community.aws.elasticache:
    name: test-please-delete
    state: present
    engine: memcached
    cache_engine_version: 5.1.10
    node_type: cache.m1.small
    num_nodes: 1
```

## Non-Compliant Code Examples{% #non-compliant-code-examples %}

```yaml
- name: Basic example
  community.aws.elasticache:
    name: "test-please-delete"
    state: present
    engine: memcached
    cache_engine_version: 1.4.14
    node_type: cache.m1.small
    num_nodes: 1
```
