In which of the following situations is the network itself not a target of attack?
A.
A denial-of-service attack on servers on a network
B.
Hacking into a router
C.
A virus outbreak saturating network capacity
D.
A man-in-the-middle attack
Explanation:
D: Although the modification of messages will often happen at the higher network layers, networks can be set up to provide robustness or resilience against interception and change of a message (man-in-the-middle attack) or replay attacks. Ways to accomplish this can be based on encryption or checksums on messages, as well as on access control measures for clients that would prevent an attacker from gaining the necessary access to send a modified message into the network.
