Certified Threat Intelligence Analyst (CTIA) — Question 57

A consortium was established in a collaborative effort to strengthen the cybersecurity posture of multiple organizations within an industry sector. The participating entities decided to adopt a threat intelligence exchange architecture in which all threat data is collected, analyzed, and disseminated through a single central hub. What type of threat intelligence exchange architecture was implemented in this scenario?

Answer options

• A. Hybrid exchange architecture
• B. Federated exchange architecture
• C. Decentralized exchange architecture
• D. Centralized exchange architecture

Correct answer: D

Explanation

The correct answer is D, as a centralized exchange architecture means that all threat data is managed through a single central hub, allowing for streamlined analysis and dissemination. The other options, such as federated and decentralized architectures, involve multiple hubs or distributed systems, which do not align with the described scenario of using a single central hub.
