Enforcing multilevel security policies in database-defined networks using row-level security

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Despite the wide of range of research and technologies that deal with the problem of routing in computer networks, there remains a gap between the level of network hardware administration and the level of business requirements and constraints. Not much has been accomplished in literature in order to have a direct enforcement of such requirements on the network. This paper presents a new solution in specifying and directly enforcing security policies to control the routing configuration in a software-defined network by using Row-Level Security checks which enable fine-grained security policies on individual rows in database tables. We show, as a first step, how a specific class of such policies, namely multilevel security policies, can be enforced on a database-defined network, which presents an abstraction of a network’s configuration as a set of database tables. We show that such policies can be used to control the flow of data in the network either in an upward or downward manner.
