CompTIA Security+ (SY0-501) — Question 249

A security administrator installed a new network scanner that identifies new host systems on the network.
Which of the following did the security administrator install?

Answer options

• A. Vulnerability scanner
• B. Network-based IDS
• C. Rogue system detection
• D. Configuration compliance scanner

Correct answer: C

Explanation

The correct answer is C, Rogue system detection, as it specifically refers to identifying unauthorized or unknown systems within a network. The other options, such as Vulnerability scanner and Network-based IDS, serve different purposes like finding security weaknesses or monitoring traffic for threats, respectively, and do not focus on discovering new hosts.
