In regards to secure coding practices, why is input validation important?

A.
It mitigates buffer overflow attacks.

B.
It makes the code more readable.

C.
It provides an application configuration baseline.

D.
It meets gray box testing standards.

Explanation:
Buffer overflow is an exploit at programming error, bugs and flaws. It occurs when an application is
fed more input data than it is programmed to handle. This may cause the application to terminate
or to write data beyond the end of the allocated space in memory. The termination of the
application may cause the system to send the data with temporary access to privileged levels in
the system, while overwriting can cause important data to be lost. Proper error and exception
handling and input validation will help prevent Buffer overflow exploits.
