A website visitor is required to provide properly formatted information in a specific field on a website form. Which of the following security measures is most likely used for this mandate?
Correct Answer: A
Input validation is a security measure used to ensure that data entered into a form or application meets specific requirements and is in the correct format. In this scenario, the website requires the visitor to provide properly formatted information in a specific field on a website form.
Implementing input validation will check the data entered by the user against predefined criteria to make sure it meets the required format. If the data does not match the expected format, the form will likely display an error message and prompt the user to correct their input before submission.
This helps prevent certain types of attacks, such as code injection or data manipulation, by ensuring that only valid and properly formatted data is accepted by the application or website.
