Abstract
The Internet of Things (IoT) is a promising theme of research. Covering subjects from micro-electronic to social sciences with a major field in computing, network and telecommunication. It is judged as the future of the today's Internet. The main idea is to benefit from an ambient intelligence instantiated by objects assisting humans in their daily tasks. One has already imagined use cases and challenging projects in separate areas, but challenge often means performances and requires expensive specific implementations or technologies. Paradoxically, this technology fragmentation starves us from a rapid growth of the IoT whereas it prevents us to be flooded by the uncharacterized traffic it would generate. Intersecting three domains of research that are Systems Monitoring and Management, Ubiquitous Computing and Cognitive Radio, we introduce our ongoing work on a new transversal use case called Ubiquitous Cognitive Systems Management (UCSM) to tackle this paradox and originate the chatty object concept.

Abstract
The era of digital avionics is opening a fabulous opportunity to improve aircraft operational functions, airline dispatch and service continuity. But arising vulnerabilities could be an open door to malicious attacks. Necessity for security protection on airborne systems has been officially recognized and new standards are actually under construction. In order to provide development assurance and countermeasures effectiveness evidence to certification authorities, security objectives and specifications must be clearly identified thanks to a security risk assessment process. This paper gives main characteristics for a security risk assessment methodology to be integrated in the early design of airborne systems development and compliant with airworthiness security standards.

Abstract
Traditional Network Intrusion Detection Systems (NIDSs) rely on either specialized signatures of previously seen attacks, or on expensive and difficult to produce labeled traffic datasets for user-profiling to hunt out network attacks. Despite being opposite in nature, both approaches share a common downside: they require the knowledge provided by an external agent, either in terms of signatures or as normal-operation profiles. In this paper we present UNIDS, an Unsupervised Network Intrusion Detection System capable of detecting unknown network attacks without using any kind of signatures, labeled traffic, or training. UNIDS uses a novel unsupervised outliers detection approach based on Sub-Space Clustering and Multiple Evidence Accumulation techniques to pin-point different kinds of network intrusions and attacks such as DoS/DDoS, probing attacks, propagation of worms, buffer overflows, illegal access to network resources, etc. We evaluate UNIDS in three different traffic datasets, including the well-known KDD99 dataset as well as real traffic traces from two operational networks. We particularly show the ability of UNIDS to detect unknown attacks, comparing its performance against traditional misuse-detection-based NIDSs. In addition, we also evidence the supremacy of our outliers detection approach with respect to different previously used unsupervised detection techniques.
