Input validation is a crucial aspect of web development that involves checking user input to ensure that it meets certain criteria before processing it. By validating user input, developers can prevent various types of security vulnerabilities, such as cross-site scripting (XSS) attacks and SQL injection attacks. Common validation techniques include checking for the correct data type, length, format, and range of input data. Implementing input validation helps to improve the overall security and reliability of a website or web application by reducing the risk of malicious activities and data corruption.
