CompTIA Security+ Question C-28

Although a vulnerability scan report shows no vulnerabilities have been discovered, a subsequent penetration test reveals vulnerabilities on the network. Which of the following has been reported by the vulnerability scan?

A. Passive scan
B. Active scan
C. False positive
D. False negative

Answer: D

With a false negative, you are not alerted to a situation when you should be alerted. A False negative is exactly the opposite of a false positive.
