Building a Fraud Taxonomy: Accelerating MTTR with Incident Playbooks
Create a structured approach to fraud incidents that enhances your response times and safeguards your organization.
A well-structured fraud taxonomy and incident playbooks can drastically reduce your MTTR.Back to all posts
Your AI model just hallucinated in production, costing $50K in customer refunds. The frantic calls from the customer service team echo in your mind as you scramble to find the root cause. Was it a data issue? A flawed algorithm? Or perhaps a subtle fraud attempt that slipped through the cracks? In today's high-stakes,
fast-paced environment, even a single incident can have dire financial implications, not to mention long-term damage to your brand's reputation. Engineering leaders must prioritize developing a robust fraud taxonomy and incident playbooks to mitigate these risks and reduce mean-time-to-resolution (MTTR).
A well-defined fraud taxonomy categorizes potential fraud incidents, enabling teams to quickly identify and respond to threats. For instance, categorize incidents into types such as identity theft, payment fraud, and account takeover. Each category should include specific signals that indicate a potential fraud attempt
like capture anomalies, voice mismatches, and mismatches-to-ID. This structured approach allows teams to prioritize their responses based on the severity of the incident and the potential impact on the organization.
### How to Implement It 1. **Define Your Fraud Categories**: Start by identifying the types of fraud that are most relevant to your organization. Consider using historical data to inform your decisions. Common categories include: - Identity Fraud - Payment Fraud - Account Takeover 2. **Create Incident Playbook
s**: Develop detailed incident playbooks for each fraud category. Each playbook should include: - **Immediate Actions**: What steps to take as soon as a fraud attempt is detected. - **Evidence Handling**: Guidelines for collecting and storing evidence, including logs, screenshots, or recordings. - **Escalation
Procedures**: When and how to escalate an incident to higher-level teams or external authorities. 3. **Integrate Decision Trees**: Use decision trees to guide teams through the incident response process. For example, if a voice mismatch is detected, the decision tree might lead to: - Step 1: Verify the identity of a
