Control response
Mitigating Controls (NIST 800-53 r5) AI
Directly enforces resource quotas and allocation limits to block an authenticated user from exhausting availability via excessive global variable use.
Requires explicit safeguards to protect the system against denial-of-service attacks originating from authenticated users.
Restricts authenticated users to the minimum privileges needed, reducing the ability to abuse global variables for resource exhaustion.

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.
