Certified Information Security Manager (CISM) — Question 880

Spoofing should be prevented because it may be used to:

Answer options

• A. assemble information, track traffic, and identify network vulnerabilities.
• B. predict which way a program will branch when an option is presented.
• C. capture information such as passwords traveling through the network.
• D. gain illegal entry to a secure system by faking the sender's address.

Correct answer: D

Explanation

The correct answer, D, highlights that spoofing can enable unauthorized access by disguising the sender's identity, which is a significant security risk. While options A and C discuss information gathering and interception, they do not directly relate to the primary concern of spoofing, which is unauthorized access. Option B is unrelated to spoofing and focuses on program behavior prediction.
