Security+ Question of the Week: Backdoor

SecurityQOW05If not by a hacker, how is a backdoor planted?

A. Disabled by a replay attack.
B. Connected to via a man‐in‐the‐middle attack.
C. Left in the code by a programmer.
D. Activated when providing legitimate credentials.

Reveal Answer

The correct answer is C.

A backdoor is an alternate means to gain access or control over a system rather than using valid authentication credentials. Planted by a hacker or left in the code by a programmer, a backdoor is not disabled by a replay attack, connected to via a man‐in‐the‐middle attack or activated when providing legitimate credentials.
