What are the best practices for input validation in web applications?
The best practices include using whitelisting, validating data on the server side, and employing regular expressions.
Can you explain why server-side validation is important?
Server-side validation is crucial because it ensures that data is checked after it leaves the user's control, preventing malicious input.
What are some common vulnerabilities related to input validation?
Common vulnerabilities include SQL injection, cross-site scripting (XSS), and buffer overflow attacks.
How can I implement input validation in my application?
You can implement it by using libraries or frameworks that provide built-in validation functions, and by writing custom validation logic.
