prevents

Secure development lifecycle mandates input validation and integrity checks that directly prevent external tampering of assumed-immutable parameters.

prevents

Application security requirements explicitly call for validation of all inputs, including hidden fields, mitigating CWE-472.

prevents

Secure coding standards require server-side verification of client-supplied data, eliminating the root cause of external control of immutable parameters.

finds

Security testing in development and acceptance will detect parameter tampering vulnerabilities before deployment.
