Question

Henry is an attacker and wants to gain control of a system and use it to flood a target system with requests, so as to prevent legitimate users from gaining access. What type of attack is Henry using?

1) Phishing attack
2) Denial of Service (DoS) attack
3) Man-in-the-middle (MitM) attack
4) SQL injection attack

Answer 1

Henry is engaging in a Denial of Service (DoS) attack, which aims to make a target system unavailable to its intended users by flooding it with excessive requests.

Step-by-step explanation:

Henry is utilizing a Denial of Service (DoS) attack. This type of attack is designed to overload a target system with requests, with the intention of preventing legitimate users from accessing the service. During a DoS attack, the attacker sends more requests to the system than it can handle, leading to slow performance or complete unavailability of the target system or network service. A DoS attack does not typically result in the theft of information or other security losses but can cause significant disruption to the operation of the website or service.

Other types of attacks mentioned, such as phishing attack, Man-in-the-Middle (MitM) attack, and SQL injection attack, serve different purposes. A phishing attack is often used to trick users into giving out personal information, a MitM attack intercepts communications between two parties to eavesdrop or alter the exchange, and an SQL injection attack targets databases through vulnerabilities in web applications.
