    Identifies unrestricted inbound access to MySQL database servers on Amazon EC2 instances, specifically targeting TCP port 3306.
  impact: |
    Unrestricted access to MySQL can lead to unauthorized data access, data manipulation, or exploitation of the database server.
  remediation: |
    Restrict inbound access on TCP port 3306 to known, necessary IP addresses or ranges, and avoid using 0.0.0.0/0 or ::/0.
