Which term describes protecting against bad data entering a software process and ensuring data are in proper form?

Protecting against bad data entering a software process and making sure inputs are in the right form is handled by checking inputs as they come in—verifying type, format, range, and other constraints, and rejecting or sanitizing anything that doesn’t meet the rules. This concept, often described as input protection and data validation, ensures only well-formed data proceed into the system, preventing errors and security issues downstream. The other terms don’t capture this ongoing vetting process as clearly. Precondition refers to assumptions that must be true before a function runs, not the act of validating and safeguarding incoming data. Postcondition describes what must be true after a function executes, which is about results rather than preventing bad input in the first place. A standalone “input protection” is incomplete because it doesn’t explicitly emphasize the validation part that enforces proper form.
