Machine learning requires large amounts of data. Despite the extensive availability of mission data collected from joint missions, military doctrine regularly compartmentalizes data to prevent accidental disclosure of operational details. Current procedures to consolidate data from different sources are manually intensive and vulnerable to insider manipulation. We desire solutions for cooperative secure learning that maintain accuracy while both protecting sensitive data sources and containing insider threats.

In this presentation, we describe a layered approach to secure, multi-party learning, in which each step in the learning process adds more security, and demonstrate its use on sensitive Security Operation Center (SOC) data. We will describe the components and flow through the system that allow for this layered security, for both single-party and multi-party learning. Our approach first combines automated anonymization and synthetic data generation to protect sensitive data with minimal loss in accuracy. We then extract feature embeddings that resist reverse engineering for sharing with the learning system via three options for privacy preserving models, and describe the training and testing process. Finally we show both performance and privacy metrics to prove this method's success in maintaining security without sacrificing performance. In most test cases, similar or better accuracy is achieved, with overall labeling accuracies ranging between 85% and 99%.

Finally, we conclude with discussion on how this work can be applied outside of cyber data, and how it can be used to make machine learning more robust in general.
