Building a Fraud Taxonomy: Playbooks for Rapid Incident Response
Implementing a robust fraud taxonomy can drastically reduce your mean-time-to-resolution (MTTR) when incidents arise.
A robust fraud taxonomy can make the difference between a quick resolution and a costly oversight.Back to all posts
## The $50K Hallucination Imagine this: Your AI model just hallucinated in production, leading to $50,000 in customer refunds. This scenario isn't far-fetched; it exemplifies the high stakes of inadequate fraud detection mechanisms. As engineering leaders, you must recognize that every second counts when fraud is at a
critical juncture. The longer it takes to resolve an incident, the greater the financial and reputational damage. Without a robust fraud taxonomy and clear incident playbooks, your team risks facing chaotic responses that can lead to costly oversights, wasted hours, and a tarnished brand image.
## Why This Matters For engineering leaders, the implications of fraud incidents extend beyond immediate monetary losses. A single oversight can erode stakeholder trust and compromise your platform's integrity. By developing a comprehensive fraud taxonomy, you create a framework that categorizes various fraud types,
enables quick identification of incidents, and informs the appropriate response. This structure not only streamlines MTTR but also enhances your team's ability to learn from past incidents, fostering a culture of continuous improvement. The cost of inaction is high; an effective response is non-negotiable in today's
competitive landscape. ## How to Implement It ### Step 1: Establish Key Fraud Signals Identify key signals that indicate potential fraud, such as: - Capture anomalies (e.g., unusual patterns in data collection) - Voice mismatches during verification processes - Mismatches between identified documents and the user’s
input ### Step 2: Create Decision Trees Develop decision trees for each identified fraud signal. These should include: - Initial assessment criteria - Escalation paths based on severity - Roles and responsibilities for team members during an incident ### Step 3: Develop Runbooks Create response runbooks detailing:
- Clear steps for evidence collection and handling - Communication protocols for internal and external stakeholders - Post-incident review processes to analyze and learn from each event ## Key Takeaways - A well-defined fraud taxonomy accelerates incident identification and resolution, directly impacting your MTTR. -
Key takeaways

Questions we hear from teams
- What is a fraud taxonomy and why is it important?
- A fraud taxonomy categorizes different types of fraud, enabling quicker identification and response during incidents, ultimately reducing MTTR.
- How can decision trees help in fraud detection?
- Decision trees guide teams through the incident response process, ensuring that actions are taken based on severity and established protocols.
- What should be included in an incident response runbook?
- An incident response runbook should include steps for evidence collection, communication protocols, and post-incident review processes.
