    Checks for inbound rules in Amazon EC2 security groups that allow unrestricted access to Redis cache server instances on TCP port 6379.
  impact: |
    Unrestricted access can expose Redis instances to unauthorized access and potential security breaches.
  remediation: |
    Restrict inbound access to Redis instances by updating EC2 security group rules to allow only specific, trusted IP addresses.
