Input Validation

Input validation is the process of checking the information that users provide to ensure it is accurate, complete, and secure. This can happen in various contexts, such as filling out forms online or entering data into a system. By validating input, organizations can prevent errors, protect against security threats, and ensure that the information being processed meets specific criteria. For example, an application might check that an email address is formatted correctly or that a password meets certain strength requirements. This helps maintain data integrity and enhances user safety.
