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

• A. Data Breach
• B. Denial of Service
• C. Information Disclosure
• D. Man-in-the-Middle

Answer: (B)

Delaying or blocking the flow of information in a system is indeed an example of a Denial of Service (DoS) threat vector. DoS attacks are specifically designed to make services unavailable to legitimate users by overwhelming the system with excessive requests or by exploiting vulnerabilities that lead to system unavailability. In the context of IACS (Industrial Automation and Control Systems), a successful DoS attack can disrupt operational processes, leading to significant downtime and potentially causing safety hazards. This threat vector affects the accessibility and reliability of the information flow within the system, hindering its intended operations. The other options represent different types of security threats. Data Breach pertains to unauthorized access to confidential information, Information Disclosure involves the unauthorized transmission of information to third parties, and Man-in-the-Middle describes an attack where an adversary intercepts communication between two parties. While these threats impact the integrity and confidentiality of data, they do not specifically focus on the interruption of service or information flow as a primary feature, which is why Denial of Service is the accurate classification for this scenario.
