What characterizes a man-in-the-middle attack?

• A. Direct server-to-server communication
• B. An attacker intercepts communication between two parties
• C. Only attacks on server databases
• D. An attack that only targets software applications

Answer: (B)

A man-in-the-middle attack is characterized by the attacker intercepting communication between two parties, which reflects the essence of this type of cyber threat. During such an attack, the malicious actor can eavesdrop, alter, or manipulate the data being exchanged without the knowledge of either party involved in the communication. This type of attack can occur in various contexts, such as unsecured Wi-Fi networks or compromised routers, making it a significant threat to confidentiality and data integrity.

In terms of context, while choices related to direct server communication, server databases, or software application attacks could be relevant aspects of cybersecurity, they do not encapsulate the core nature of a man-in-the-middle attack. The defining feature of this attack is the interception of data in transit, enabling the attacker to position themselves between legitimate users or systems, which is why the correct answer focuses specifically on the interception of communication.
