What does 'infrastructure' refer to in the context of the Diamond Model?

In the Diamond Model, 'infrastructure' specifically refers to the software and hardware that are utilized by the target, which includes any systems or devices that the adversary may exploit. This concept is critical in understanding how adversaries conduct attacks, as it focuses on the technical components that can be manipulated or compromised.

Recognizing the infrastructure helps analysts determine the methods and tools that adversaries may use, as well as the potential vulnerabilities within these systems that could be exploited. This element plays a significant role in the behavior of both the adversary and the victim, providing insights into strategic and tactical operations within the cyber threat landscape.

Other options, although relevant to security, do not capture the specific meaning of 'infrastructure' in the Diamond Model framework. They pertain to broader concepts in cybersecurity or operational contexts rather than the technical elements that the term is meant to convey within the model.
