Question

Mark works as a Network Administrator for Perfect Inc. The company has both wired and wireless networks. An attacker attempts to keep legitimate users from accessing services that they require. Mark uses IDS/IPS sensors on the wired network to mitigate the attack. Which of the following attacks best describes the attacker's intentions?

Why each option

The attacker's goal is to prevent legitimate users from accessing network services, which is the defining characteristic of a Denial of Service attack.

ALand attack

A Land attack is a specific type of DoS attack using spoofed packets where the source and destination IP are the same, making it a subcategory rather than the best general description of the attacker's intent.

BInternal attack

An internal attack originates from within the organization's own network or by an insider, and there is no indication in the scenario that the attacker is an insider.

CDoS attackCorrect

A Denial of Service (DoS) attack is specifically designed to disrupt or deny access to services for legitimate users by overwhelming or crashing the target system. The use of IDS/IPS sensors to detect and mitigate the attack is a standard defensive response to DoS activity on a wired network. The attacker's intention matches the DoS definition precisely - blocking access rather than stealing data or gaining entry.

DReconnaissance attack

A reconnaissance attack focuses on gathering information about a target network passively, not on disrupting service availability.
