Abstract: Systems and techniques are described for ensuring that policies are consistently applied to traffic across an overlay network. An application identifier associated with a forward traffic flow and a corresponding reverse traffic flow can be determined by a device that routes packets of both the forward traffic flow and the corresponding reverse traffic flow. Next, an overlay header can be added to each packet in the forward traffic flow and to each packet in the corresponding reverse traffic flow, wherein the overlay header comprises the application identifier, a policy identifier, and a policy action. Each device in the overlay network can then apply the policy action specified in the overlay header of each packet that it routes.

Abstract: Systems and techniques are described for preventing data leaks from a network. A set of sensitive files or sensitive data that includes sensitive information can be received, and a first set of labels can be determined based on the set of sensitive files or sensitive data. An apparatus can then receive data that is to be checked for sensitive information, and determine a second set of labels based on the data. Next, the apparatus can match the second set of labels with the first set of labels. The apparatus can then determine whether or not the data includes sensitive information based on a result of said matching, and perform a data leak prevention action if it is determined that the data includes sensitive information.
