Episode 44 — Model intrusions with the diamond for clarity
The Diamond Model of Intrusion Analysis provides a non-linear framework that emphasizes the relationships between the four core facets of every security event: the adversary, the infrastructure, the capability, and the victim. This episode focuses on using the Diamond Model to organize complex data and identify "missing links" in your investigation, such as when you have the "malware" (capability) and the "target" (victim) but lack the "C2 server" (infrastructure). We explain how to use "pivot lines" to move between the vertices of the diamond, showing the logical flow of an attack. For the GCTI exam, you should be proficient in building a Diamond Model for a given case study to demonstrate a holistic understanding of the threat. Troubleshooting involves recognizing when an "activity thread" connects multiple diamonds, suggesting a prolonged campaign by a single persistent actor. Modeling with the diamond provides a multi-dimensional clarity that simple lists of indicators cannot match, making it an essential tool for high-level analytical communication.
