What type of attack involves delaying or blocking the flow of information?

The type of attack that involves delaying or blocking the flow of information is indeed a Denial of Service (DoS) attack. In a DoS attack, the attacker aims to make a network service unavailable to its intended users by overwhelming the service with a flood of illegitimate requests or traffic. This saturation can prevent legitimate users from accessing the service, effectively disrupting normal operations.

The essence of a DoS attack lies in its objective to deny access to resources, which may include causing delays in information flow or blocking it altogether. By inundating a target with excessive requests, the attacker can cause significant disruptions and degrade performance to the point where services can become completely inaccessible for legitimate users.

While other types of attacks, such as malware infections, phishing attacks, and man-in-the-middle attacks, may have their own malicious objectives, they typically do not primarily focus on delaying or blocking the flow of information in the same manner that DoS attacks do. Instead, those attacks may aim to steal data, manipulate communications, or gain unauthorized access to systems, thus having different impact and motivations compared to a Denial of Service attack.
