C Correct answer
Explanation

To solve this question, the user needs to be familiar with common cybersecurity threats.

Now, let's go through each option and explain why it is right or wrong:

A. Repudiation: This option refers to an attacker's attempt to deny that they have performed an action. It does not involve impersonating another user or using a false identity to gain access to a system.

B. Eavesdropping: This option refers to an attacker's attempt to intercept and listen to communications between two parties. It does not involve using a false identity to gain access to a system.

C. Spoofing: This option is correct. Spoofing involves an attacker using a false identity to gain access to a system. This can be accomplished through a variety of means, such as email spoofing or IP address spoofing.

D. Hijacking: This option refers to an attacker's attempt to take control of a system or communication channel. It does not necessarily involve using a false identity, although it can be a means to that end.

The Answer is: C

AI explanation

Correct answer: Spoofing.

Spoofing means impersonating another user, device, or system (falsifying an identity, IP address, email header, etc.) to gain unauthorized access or trust. That directly matches "gaining access by using a false identity."

Repudiation is denying that an action occurred (or denying responsibility), not identity theft. Eavesdropping is passively intercepting communications without necessarily impersonating anyone. Hijacking is taking over an already-established, legitimate session/connection rather than presenting a false identity to gain initial access. None of these three involve pretending to be someone else to get in.
