The Diamond Model of Intrusion Analysis

The Diamond Model of Intrusion Analysis is a cybersecurity framework that helps analysts understand and analyze cyber threats and attacks. It uses four components to visualize the relationship between the attacker, victim, and infrastructure during a cyber-attack:

• Adversary: The actor who uses a capability against the victim
• Capability: The tools, techniques, and procedures used by the adversary to attack the victim
• Infrastructure: The underlying infrastructure
• Victim: The target of the attack

The Diamond Model uses mathematical and cognitive reasoning to trace and authenticate cyber threats. It's a simple yet powerful model that helps analysts create a comprehensive view of cyber attacks.

Here are some ways the Diamond Model is used:

• Documenting, analyzing, and correlating intrusions: The Diamond Model can document, analyze, and correlate intrusions into an organization's digital, network, and physical environments.
• Describing threat actor behaviors: The Diamond Model can describe the behaviors of threat actors.
• Ordering events: The Diamond Model can help order events because threat actors don't take actions in isolation.
• Creating activity threads: Activity threads can be constructed as adversary-victim pairs.
• Creating pivots: The logical deductions from traversing the Diamond are called pivots.
