CAS-002 Question #128: Real Exam Question with Answer & Explanation
The correct answer is C: Network security may need to be increased by reducing the number of available physical. With most conference attendees using wireless smartphones, the unused physical network ports represent unnecessary attack surface that should be reduced to improve security of conference resources.
Question
When attending the latest security conference, an information security administrator noticed only a few people carrying a laptop around. Most other attendees only carried their smartphones. Which of the following would impact the security of conference's resources?
Options
- AWireless network security may need to be increased to decrease access of mobile devices.
- BPhysical security may need to be increased to deter or prevent theft of mobile devices.
- CNetwork security may need to be increased by reducing the number of available physical
- DWireless network security may need to be decreased to allow for increased access of mobile
Explanation
With most conference attendees using wireless smartphones, the unused physical network ports represent unnecessary attack surface that should be reduced to improve security of conference resources.
Common mistakes.
- A. Wireless network security should be increased rather than decreased as more mobile devices connect wirelessly, creating a larger wireless attack surface that requires stronger controls, not weaker ones.
- B. Increasing physical security to deter theft of mobile devices is a valid concern for attendee property but does not directly address the security of the conference's network resources, which is the focus of the question.
- D. Decreasing wireless network security to allow increased mobile device access would weaken authentication and encryption protections, introducing additional risk rather than reducing it.
Concept tested. Reducing physical network attack surface in public venues
