Introduction to Incident Response in the Dark Web Era
Cyber Threat Intelligence (CTI) plays a crucial role in incident management, especially when dealing with Dark Web breaches. Utilizing the NIST Framework, we can outline the Dark Web monitoring lifecycle into seven distinct stages: Preparation, Detection, Analysis, Containment, Eradication, Recovery, and Post Activity. This guide delves into the practical aspects of these stages, ensuring your team is equipped to handle threats effectively.
The Team and Their Roles In Dark Web monitoring, the coordination between Cyber Threat Intelligence (CTI), Security Operations Center (SOC), and Incident Response (IR) teams is vital. Each team plays a specific role, whether it’s handling CTI alerts, investigating threats, or executing response actions. The RACI matrix in this playbook outlines the responsibilities and accountabilities of each team.
Preparation: The First Line of Defense Monitoring the Dark Web involves setting up alerts for mentions of your company, including names, domains, IP addresses, and more. Consider using tools like VPNs, Tor, and specialized monitoring services to streamline this process.
Detection: Identifying the Threats Effective detection includes monitoring various types of alerts, such as mentions of your company on the Dark Web or in compromised databases. Services like Kaspersky Digital Footprint Intelligence can be invaluable here.
Workflow of Procedures: From Analysis to Recovery The procedure begins with analyzing CTI alerts, evaluating threats, profiling attackers, and identifying key artifacts. It progresses through raising an incident, investigation, and culminates in containment, eradication, and recovery stages. Each step is crucial and detailed in the playbook.
Response Playbooks: Tailored Actions for Specific Breaches We provide detailed playbooks for three types of incidents: Data Exfiltration, Account Compromise, and Remote Access Compromise. These playbooks guide you through verifying data samples, identifying the source of the breach, and taking necessary containment and eradication steps.
Learning from Incidents: The Post-Incident Phase After an incident, it’s crucial to perform a root-cause analysis, update your threat model, and refine your response plans. This section helps you understand how to extract lessons from every incident to strengthen your future responses.
Appendix: Understanding the Diagrams The playbook contains various diagrams for better visual understanding. Each element, whether it’s an event, task, gateway, or sub-procedure, is explained for easy reference.
