Project Synopsis: CASTLE aims to develop a toolkit that instantiates realistic network environments and trains artificial intelligence agents to support defense against advanced persistent cyber threats. Researchers will explore the use of reinforcement learning to automate network hardening and ultimately accelerate cybersecurity assessments with approaches that are automated, repeatable, and measurable. As an added benefit, CASTLE also will promote open, rigorous evaluations of defensive approaches by publicly releasing toolkit-generated datasets, which can serve as benchmarks for rigorous measurement of cybersecurity performance beyond the life of the program.
