The rapid growth of the Internet is, in part, powered by the broad participation of numerous vendors building network components. All these network devices require that they be properly configured and maintained, which creates a challenge for system administrators of complex networks with a growing variety of heterogeneous devices. This challenge is true for today's networks, as well as for the networking architectures of the future, such as Named Data Networking (NDN). This paper gives a preliminary design of an NDNconf framework, an adaptation of a recently developed NETCONF protocol, to realize unified configuration and management for NDN. The presented design is built leveraging the benefits provided by NDN, including the structured naming shared among network and application layers, stateful data retrieval with name-based interest forwarding, in-network caching, data-centric security model, and others. Specifically, the configuration data models, the heart of NDNconf, the elements of the models and models themselves are represented as secured NDN data, allowing fetching models, fetching configuration data that correspond to elements of the model, and issuing commands using the standard Interest-Data exchanges. On top of that, the security of models, data, and commands are realized through native data-centric NDN mechanisms, providing highly secure systems with high granularity of control.

The Internet of Things (IoT) integrates the Internet and electronic devices belonging to different domains, such as smart home automation, industrial processes, military applications, health, and environmental monitoring. Usually, IoT devices have limited resources and Low Power and Lossy Networks (LLNs) are being used to interconnect such devices. Routing Protocol for Low-Power and Lossy Networks (RPL) is one of the preferred routing protocols for this type of network, since it was specially developed for LLNs, also known as IPv6 over Low-Power Wireless Personal Area Networks (6LoWPAN). In this paper the most well-known routing attacks against 6LoWPAN networks were studied and implemented through simulation, conducting a behavioral analysis of network components (resources, topology, and data traffic) under attack condition. In order to achieve a better understanding on how attacks in 6LoWPAN work, we first conducted a study on 6LoWPAN networks and RPL protocol functioning. Furthermore, we also studied a series of well-known routing attacks against this type of Wireless Sensor Networks and these attacks were then simulated using Cooja simulator provided by Contiki operating system. The results obtained after the simulations are discussed along with other previous researches. This analysis may be of real interest when it comes to identify indicators of compromise for each type of attack and appropriate countermeasures for prevention and detection of these attacks.
