Input validation is the practice of ensuring that data supplied by a user or another program meets certain criteria before it is processed. Think of it as a gatekeeper for information, checking that everything is in order before allowing it to pass through. This process is fundamental to creating robust, secure, and reliable software applications. Without it, systems can be vulnerable to a wide array of problems, from incorrect data leading to malfunctions, to security breaches with potentially severe consequences. Essentially, input validation helps protect systems by ensuring that only properly formed and expected data is accepted and processed.
