Delaying or blocking the flow of information in a system is an example of which threat vector?

Delaying or blocking the flow of information in a system is primarily associated with a Denial of Service (DoS) threat vector. This type of threat is characterized by efforts to make information or resources unavailable to the intended users. In the context of risk assessment, a Denial of Service attack aims to disrupt the normal functioning of a service, server, or network by overwhelming it with traffic or otherwise preventing legitimate users from accessing it.

When the flow of information is impeded, whether through excessive requests, targeted attacks, or exploitation of system vulnerabilities, it can have significant consequences for organizations. This can lead to downtime, loss of productivity, and can potentially harm the organization's reputation if the disruption impacts customers.

The other options represent different types of threat vectors: Information Disclosure refers to unauthorized access and retrieval of confidential information, Data Manipulation involves unauthorized modification or destruction of data, and Unauthorized Access implies gaining entry into a system or network without permission. Each of these has distinct characteristics and implications, but they do not specifically pertain to the limiting or blocking of information flow in the same manner that a Denial of Service does.
