Mitigating Controls (NIST 800-53 r5) AI
Directly enforces validation and neutralization of special elements in query input to the fenced Db2 environment, blocking the exact CWE-1284 flaw that enables authenticated DoS.
Restricts the privileges of authenticated users so they cannot reach or abuse the vulnerable data-query logic in the fenced Db2 environment.
Implements mechanisms to detect and throttle resource-exhaustion attempts against the Db2 fenced process before denial of service occurs.

Security testing in development can detect missing quantity validation but does not itself implement the control.
Secure development lifecycle mandates input validation for quantity fields, directly preventing CWE-1284.
Application security requirements explicitly call for validation of size/length inputs, mitigating CWE-1284.
Secure architecture principles encourage robust input handling but do not specifically address quantity validation.
Secure coding standards require explicit checks on numeric quantity inputs, fully addressing CWE-1284.
