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.
To answer this question, the user needs to be familiar with the basic security concepts.
The ability of users to deny that they performed specific actions or transactions is known as repudiation. This can occur when a user denies that they have performed an action such as sending an email or making a purchase.
