finds

Security testing can detect missing-parameter issues but does not prevent them at design time.

prevents

Secure development lifecycle includes input validation and parameter handling requirements that reduce improper parameter handling.

prevents

Application security requirements explicitly call for validation of inputs and parameters, mitigating missing or undefined arguments.

prevents

Secure coding standards directly address proper handling of function parameters and input validation.
