Software-defined network (SDN) radically changes the network architecture by decoupling
the network logic from the underlying forwarding devices. This architectural change …

Over the years, switches and network routers have been compromised frequently, and a lot
of vulnerabilities have occurred in network infrastructure. Secure routing (SR) is one of the …

Virtual switches are a crucial component of SDN-based cloud systems, enabling the
interconnection of virtual machines in a flexible and" software-defined" manner. This paper …

Networks are vulnerable to disruptions caused by malicious forwarding devices. The
situation is likely to worsen in Software Defined Networks (SDNs) with the incompatibility of …

As network policies are becoming increasingly nuanced and complex, so too are the
mechanisms required to ensure that the network is functioning as intended. In particular …

Abstract Software-Defined Networking (SDN) greatly simplifies middlebox policy
enforcement. Middleboxes need tag packet headers to avoid forwarding ambiguity on SDN …

With the increasing scale of communication networks, the likelihood of failures grows as
well. Since these networks form a critical backbone of our digital society, it is important that …

We quantify the threat of network adversaries to inducing\emph {network overload}
through\emph {routing attacks}, where a subset of network nodes are hijacked by an …

Private networks are typically assumed to be trusted as security mechanisms are usually
deployed on hosts and the data plane is managed in-house. The increasing number of …

Software-defined networks are vulnerable to attacks by compromised switches because
commonly used programmable software switches are risky than traditional hardware ones …
