abstract = {The Internet of Things (IoT) is more and more present in fundamental aspects of our societies and personal life. Billions of objects now have access to the Internet. This networking capability allows for new beneficial services and applications. However, it is also the entry-point for a wide variety of cyber-attacks that target these devices. The security measures present in real IoT systems lag behind those of the standard Internet. Security is sometimes completely absent. Moving Target Defense (MTD) is a 10-year-old cyber-defense paradigm. It proposes to randomize components of a system. Reasonably, an attacker will have a higher cost attacking an MTD-version of a system compared with a static-version of it. Even if MTD has been successfully applied to standard systems, its deployment for IoT is still lacking. In this paper, we propose a generic MTD framework suitable for IoT systems: IANVS (pronounced Janus). Our framework has a modular design. Its components can be adapted according to the specific constraints and requirements of a particular IoT system. We use it to instantiate two concrete MTD strategies. One that targets the UDP port numbers (port-hopping), and another a CoAP resource URI. We implement our proposal on real hardware using Pycom LoPy4 nodes. We expose the nodes to a remote Denial-of-Service attack and evaluate the effectiveness of the IANVS-based port-hopping MTD proposal.},

abstract = {This demonstration defines a small IoT wireless network that uses TI CC2538-OpenMote as hardware platform and state-of-the-art IETF network standards such as 6LoWPAN, RPL, and CoAP implemented by ContikiOS. The IoT nodes are controlled from outside the IoT network using end-to-end connectivity provided by IPv6-CoAP messages. We implement a man-in-the-middle attack that disrupts the normal behavior of the system. Our attack leverages on the inherent hierarchical routing topology of RPL-based IoT networks. The demonstration aims at highlighting the need for end-to-end source-authentication and authorization enforcement of information even inside a trusted IoT network. We also provide some insights on how these services can be offered in a IoT-friendly way.},

abstract = {The need to connect things is skyrocketing and the Internet of Things is drawing a clear pattern of the need for smarter things. We are proposing an upgrade of Constrained Application Protocol (CoAP) built upon the 3 main networking needs of a connecting thing: The discovery, the synchronous and asynchronous communications and the publish/subscribe. CoAP 2.0 as we call it, will allow building smart things independently of the use-case, with a single protocol, fewer lines of codes and with less impact on the memory.},
