info:
  name: EFS Encryption - Disabled
  author: DhiyaneshDK
  severity: medium
  description: |
    Ensure that the data available on your Amazon EFS file systems is encrypted at rest 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 encryption for AWS EFS by configuring encryption at rest in the EFS settings to protect data from unauthorized access.
