An application developer has tested some of the known exploits within a new application. Which of the
following should the administrator utilize to test for unidentified faults or memory leaks?

A.
XSRF Attacks

B.
Fuzzing

C.
Input Validations

D.
SQL Injections

Explanation:
Fuzzing is a software testing technique that involves providing invalid, unexpected, or random data to as
inputs to a computer program. The program is then monitored for exceptions such as crashes, or failed
validation, or memory leaks.
Incorrect Answers:
A: XSRF or cross-site request forgery applies to web applications and is an attack that exploits the web
application’s trust of a user who known or is supposed to have been authenticated. This is often
accomplished without the user’s knowledge.
C: 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.
D: SQL injection attacks use unexpected input to a web application to gain access to the database used by
web application. You can protect a web application against SQL injection by implementing input validation
and by limiting database account privileges for the account used by the web server and the web
application.
