OpenFlow flow tables in Open vSwitch contain valuable information about installed flows, priorities, packet actions and routing policies. Their importance is emphasised when collocated tenants compete for the limited entries available to install flow rules. OpenFlow flow tables are a security asset that requires confidentiality and integrity guarantees. However, commodity software switch implementations - such as Open vSwitch - do not implement protection mechanisms capable to prevent attackers from obtaining information about the installed flows or modifying flow tables. We adopt a novel approach to enabling OpenFlow flow table protection through decomposition. We identify core assets requiring security guarantees, isolate OpenFlow flow tables through decomposition and implement a prototype using Open vSwitch and Software Guard Extensions enclaves. An evaluation of the prototype on a distributed testbed both demonstrates that the approach is practical and indicates directions for further improvements.
