Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly requires validation and sanitization of all inputs (patient_id) to reject malformed or malicious SQL syntax before it reaches the database.

SC-7 Boundary Protection partial match
prevent

Boundary protection devices or WAF rules can inspect and block SQL injection payloads targeting /admin/patient_action.php at the network or application perimeter.

AC-3 Access Enforcement partial match
prevent

Enforces that only properly formed, authorized queries are executed against patient records, preventing unauthorized data manipulation via unsanitized input.
