The correct answer is (A) listen to private voice or data transmission. Eavesdropping, in the context of computer security and networks, refers to the unauthorized interception of private communications, such as data packets or voice calls, being transmitted over a network.
– Eavesdropping is a passive attack, meaning the attacker intercepts data without altering it or disrupting the communication flow.
– It is a breach of confidentiality, one of the key principles in computer security.
– Common methods include packet sniffing, wiretapping (in a broader sense extending to network cables), and intercepting wireless signals.
Options (B), (C), and (D) describe other types of malicious activities:
– (B) preventing the system from processing or responding to legitimate users is characteristic of a Denial-of-Service (DoS) attack.
– (C) disabling network connectivity can be a form of DoS attack or physical sabotage.
– (D) deleting data is a form of data tampering or destruction, related to breaches of integrity and availability.
