Which of the following techniques can be used to prevent the disclosure of system information resulting from arbitrary inputs when implemented properly?
A.
Fuzzing
B.
Patch management
C.
Error handling
D.
Strong passwords
Explanation:
Exception handling is an aspect of secure coding. When errors occur, the system should revert back to a secure state. This must be coded into the system by the
programmer, and should capture errors and exceptions so that they could be handled by the application.
Incorrect Answers:
A: 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.
B: Patch management is the process of maintaining the latest source code for applications and operating systems. This helps protect a systems from known
attacks and vulnerabilities.
D: Passwords are used to control access to systems as part of a user authentication process. Strong passwords make it harder for attackers to guess or crack the
passwords.http://en.wikipedia.org/wiki/Fuzz_testing
