Enforcing Context-Aware BYOD Policies with In-Network Security

Bring Your Own Device, or BYOD, has become the new norm for many enterprise networks; but it also raises security concerns. We present our vision of programmable in-network security, and sketch an initial system design, Poise. Poise has a high-level policy language that can express a wide range of existing and new security policies. These policies can then be compiled to device con- figurations to collect device/apps information, as well as switch programs in P4 that enforce security inside the network. Our initial results seem promising — Poise runs with reasonable overhead, and it successfully detects policy violations for seven useful BYOD policies.
