Which of the following describes a rogue device that mimics a legitimate device?

The concept of a rogue device that mimics a legitimate device is best captured by the term impersonation. Impersonation occurs when an unauthorized entity disguises itself as a trusted or legitimate device to gain access to sensitive information or systems. This malicious tactic aims to mislead users or systems into believing that they are interacting with a genuine device.

In the context of network security, such impersonation can lead to significant security breaches, as it allows an attacker to bypass authentication mechanisms, execute harmful commands, or eavesdrop on sensitive communications. This practice underlines the importance of implementing robust security measures, such as authentication protocols and device verification processes, to identify and prevent unauthorized access.

Other options like phishing and man-in-the-middle do involve deceptive tactics but are not primarily centered on the concept of mimicking a legitimate device. Phishing typically involves tricking users into providing personal information through fraudulent emails or websites, while a man-in-the-middle attack refers to intercepting and altering communications between two parties. Interception similarly relates to unauthorized access to data but does not specifically describe the act of mimicking a legitimate device.
