id: cache-redis-encryption-disabled

info:
  name: ElastiCache Redis In-Transit and At-Rest Encryption - Disabled
  author: DhiyaneshDK
  severity: high
  description: |
    Ensure that your Amazon ElastiCache Redis cache clusters are encrypted in order to meet security and compliance requirements.
  impact: |
    Sensitive data transmitted or stored in Redis could be exposed, leading to potential data breaches or unauthorized access.
  remediation: |
    Enable in-transit and at-rest encryption in the Redis cluster settings to protect sensitive data.
