Which of the following is a common coding error in which boundary checking is not performed?

A.
Input validation

B.
Fuzzing

C.
Secure coding

D.
Cross-site scripting

Explanation:
Input validation is a defensive technique intended to mitigate against possible user input attacks,
such as buffer overflows and fuzzing. Input validation checks every user input submitted to the
application before processing that input. The check could be a length, a character type, a

language type, or a domain.
