  name: SQS Queue Exposed
  author: DhiyaneshDK
  severity: high
  description: |
    Identify any publicly accessible Amazon SQS queues and update their permissions in order to protect against unauthorized users.
  impact: |
    Exposing an SQS Queue can lead to unauthorized access, allowing attackers to intercept, delete, or manipulate messages, disrupting application workflows.
  remediation: |
    Restrict access to the SQS Queue using IAM policies, ensuring only authorized users and services have necessary permissions, and enable server-side encryption for data protection.
