Understanding DDoS Attacks

A.

The type of attack described in the question is a Denial-of-Service (DoS) attack, and the correct answer is A.

A DoS attack is a type of cyberattack that is launched against a network or system to prevent legitimate users from accessing it. In this type of attack, the attacker floods the target network with a large number of requests or data packets, which saturates the network's resources and disrupts its ability to function correctly. As a result, legitimate users are unable to access the network or its services.

In the case described in the question, the attacker is sending a large number of protocol packets to the network to saturate its resources and disrupt connections between services. This type of attack is often referred to as a protocol flooding attack, where the attacker sends a large number of protocol-specific packets, such as TCP/IP, UDP, or ICMP packets, to the target network.

The goal of a DoS attack is to overwhelm the network or system with traffic, rendering it inaccessible to legitimate users. This type of attack can have severe consequences, including loss of revenue, reputation damage, and disruption of critical services. It can also be used as a diversionary tactic to distract security teams while the attacker carries out other attacks.

In summary, a DoS attack is a type of cyberattack that floods a network or system with traffic to prevent legitimate users from accessing it. The attack described in the question is a protocol flooding attack, which is a specific type of DoS attack that targets the network's protocol layer.
