Data Driven Data Center Network Security

Large scale datacenters are becoming the compute and data platform of large enterprises, but their scale makes them difficult to secure applications running within. We motivate this setting using a real world complex scenario, and propose a data-driven approach to taming this complexity. We discuss several machine learning problems that arise, in particular focusing on inducing so-called whitelist communication policies, from observing masses of communications among networked computing nodes. Briefly, a whitelist policy specifies which machine, or groups of machines, can talk to which. We present some of the challenges and opportunities, such as noisy and incomplete data, non-stationarity, lack of supervision, challenges of evaluation, and describe some of the approaches we have found promising.
