finds

Security testing in development can detect missing handling of undefined values before release.

prevents

Secure development life cycle requires handling of invalid/undefined inputs during design and coding.

prevents

Application security requirements include validation of all parameters and handling of unsupported values.

prevents

Secure architecture principles mandate explicit handling of undefined or unsupported states.

prevents

Secure coding standards directly require defensive checks for undefined or unsupported parameter values.

degrades

Change management ensures structural consistency is preserved when modifications are introduced.
