Input Validation and Sanitization
Input validation and sanitization are critical security measures used in software development to protect applications from a wide range of security vulnerabilities, particularly those related to malicious input or user data. These practices help ensure that the data received by an application is safe, reliable, and free from vulnerabilities that attackers could exploit.
In this chapter, we’re going to cover input validation and sanitization by looking at the following main topics:
- Input validation
- Input sanitization
- Language-specific defenses
- Buffer overflows
- Example of enterprise input validation and sanitization
By the end of this chapter, the reader will have a good grasp of how vital validation and sanitation of the input received is in protecting the application.
