TITAN: A State-of-the-Art Graph Mining Framework for Cyber Threat Intelligence
TITAN is a state-of-the-art graph mining framework developed to generate real-time cyber threat intelligence. It is specifically designed to tackle challenges related to scaling, integrating diverse telemetry, and adapting to an evolving security landscape. The framework features a dynamic threat intelligence graph that maps relationships among millions of entities, incidents, and organizations, enhancing the detection and analysis of potential cyber threats.
Dynamic Threat Intelligence Graph
A key feature of TITAN is its Dynamic Threat Intelligence Graph. The framework uses a k-partite graph architecture with five hierarchical node layers. These layers represent organizations, incidents, alerts, entities, and parent entities. This design allows for a comprehensive understanding of complex relationships and interactions within the cyber threat landscape.
TITAN conducts real-time updates with telemetry every hour, enabling the decay and pruning of outdated intelligence. Such updates ensure that the information remains current and relevant, which is critical for effective threat detection. The framework employs a reputation scoring system, with scores ranging from 0, indicating benign, to 1, indicating malicious. Unknown entities are assigned a score of 0.5. Reputation propagation algorithms, specifically label propagation (LP), are used to uncover hidden threat actor infrastructure by linking entities based on their associations.
Integration and Performance Metrics
TITAN is integrated into Microsoft’s Unified Security Operations Platform (USOP), which is utilized by numerous organizations worldwide. This integration allows for a comprehensive view of threats across various security domains. Performance metrics for TITAN highlight its efficiency and effectiveness in threat intelligence generation, achieving a macro-F1 score of 0.89 and a precision-recall AUC of 0.94. These metrics demonstrate high accuracy in threat detection.
TITAN has recorded a sixfold increase in non-file threat intelligence, a 21% rise in incident disruption rates, and a reduction in response times by a factor of 1.9. Expert evaluations indicate a 99% precision rate in threat disruption, underscoring the reliability of the system.
Scalability and Innovation
TITAN’s architecture is designed to handle large volumes of data, leveraging technologies such as PySpark for large-scale data processing. Azure Synapse and Azure Data Lake Storage are used for secure alert management. This scalable framework is capable of identifying millions of high-risk entities weekly and has shown consistent performance across geographical regions.
TITAN distinguishes itself from traditional threat intelligence platforms. Unlike Security Knowledge Graphs (SKGs), it dynamically generates new threat intelligence in real time rather than merely structuring known information. Its advanced algorithms improve accuracy in identifying threats and reduce false positives, making it a vital tool for cybersecurity defenses. TITAN’s innovations significantly enhance the accuracy, efficiency, and scope of cyber threat intelligence, providing organizations with a powerful resource to respond to sophisticated cyber threats in a timely manner.
