Study Notes

The Diamond Model of Intrusion Analysis

The Diamond Model details fundamental aspects of malicious activity
Aims to discover, develop, track, group, and counter malicious actors
Developed in 2006 by senior analysts seeking a more scientific approach to intrusion analysis
Originally viewed as an art rather than a science
The Diamond Model applies scientific rigor and standardized methodologies

Why the Diamond Model Matters

Offers a framework for more effective mitigation strategies
Integrates information assurance strategies and cyber threat intelligence
Increases analytic efficiency and effectiveness
Highlights analytic opportunities and intelligence gaps
Formalizes cyber ontologies, taxonomies, and threat intelligence sharing
Provides context and relationships to previously isolated indicators

The Diamond Model's Atomic Elements

The core element is the event
Every intrusion event possesses four key features: adversary, capability, infrastructure, victim
Features are connected by relationships
Analysts use analytic pivoting to move from one feature in the diamond to another
Allows analysts to maximize opportunities and clarify intelligence gaps

Meta-Features of the Diamond Model

Meta-features are additional characteristics of events
Include: timestamp, phase, result, direction, methodology, resources, and infrastructure
Allow for more comprehensive modeling and analysis

Extended Diamond Model

Adds technology and social-political meta-features
Technology connects infrastructure and capability
Social-political represents the relationship between adversary and victim, including needs, aspirations, and intent
Enables analytic pivoting to understand the underlying reasons behind adversary actions and improve mitigation strategies

Activity Threads

Organized by steps and causal relationships within malicious activity
Represents a minimum of two or more events, including selection of target, malicious action
Can analyze patterns in adversary actions
Illustrates how adversaries leverage knowledge

Activity-Attack Graphs

Integration of activity threads and attack graphs to understand adversary operations and processes
Facilitates more effective defense strategies
Allows for proactive mitigation of current and future potential attacks
Useful for developing common adversary processes
Applicable to various mitigation planning frameworks, including JIOPE, Kill Chain analysis

Analytic Problem Definition

Defining the analytic problem to be solved when grouping events
Determining how events will be grouped
