Talk 4

The possibilities, limitations, pros, and cons of using programmable data planes for network security

Recent advances in programmable network architectures allow them to run complex algorithms in the data plane of a network, i.e., with visibility of all packets and at line rate. While this new concept receives great attention in the networking community, it is barely used for security purposes. This is surprising because many network security solutions suffer from limitations induced by off-path traffic analysis (e.g., w.r.t. required sampling, induced delay, and needed storage), all of which do not apply for processing traffic directly in the data plane.

In this talk, we bring the concept of programmable data planes closer to the security community by (i) explaining what is (and is not) possible in programmable data planes and (ii) discussing when it makes (no) sense to do something in the data plane.
