finds

Security testing can detect type-validation flaws but does not prevent them during development.

prevents

Secure development lifecycle mandates input validation and type checking to prevent improper type handling.

prevents

Application security requirements explicitly include validation of input data types and formats.

prevents

Secure architecture principles promote defensive input handling and type enforcement at system boundaries.

prevents

Secure coding standards directly require proper type validation of all external inputs.
