Le Libre : catalyseur de l'Humanisme ?

National audienceL'ingénieur humaniste doit comprendre le monde et œuvrer à la diffusion large et sans barrières ni discrimination de la connaissance. Ce concept résonne largement avec celui de la culture libre, qui promeut la liberté de distribution des biens non matériels tels que logiciels, inventions, connaissances, etc.. Nous défendons donc dans cette communication que la sensibilisation à la culture libre est à la fois une opportunité et une nécessité pour la formation d'ingénieurs humanistes. Nous proposons également quelques pistes de réflexion pour l'intégration de cette culture libre dans notre contexte

A survey of IoT protocols and their security issues through the lens of a generic IoT stack

International audienceThe Internet of things (IoT) is rapidly growing, and many security issues relate to its wireless technology. These security issues are challenging because IoT protocols are heterogeneous, suit different needs, and are used in different application domains. From this assessment, we identify the need to provide a homogeneous formalism applying to every IoT protocols. In this survey, we describe a generic approach with twofold challenges. The first challenge we tackle is the identification of common principles to define a generic approach to compare IoT protocol stack. We base the comparison on five different criteria: the range, the openness of the protocol, the interoperability, the topology and the security practices of these IoT protocols. The second challenge we consider is to find a generic way to describe fundamental IoT attacks regardless of the protocol used. This approach exposes similar attacks amongst different IoT protocols and is divided into three parts: attacks focusing on packets (passive and active cryptographic attacks), attacks focusing on the protocol (MITM, Flooding, Sybil, Spoofing, Wormhole attacks) and attacks focusing on the whole system (Sinkhole, Selective forwarding attacks). It also highlights which mechanisms are different between two protocols to make both of them vulnerable to an attack. Finally, we draw some lessons and perspectives from this transversal study

IoTMap: A protocol-agnostic multi-layer system to detect application patterns in IoT networks

International audienceThe growth of the Internet of Things (IoT) results in a proliferation of different protocols (ZigBee, Bluetooth, 6LowPAN, Z-Wave, Wi-Fi, etc.). Organizations tend to quickly deploy several IoT applications over time and thus face heterogeneous IoT systems, combining different IoT protocols in different places of the overall system. This heterogeneity of protocols makes these networks hard to monitor or control, and some misconfigurations or unexpected device behaviours may even expose users to security issues. In this work, we propose the IoTMap system. IoTMap models interconnected and heterogeneous IoT networks, combining different protocols, by providing a generic stack and a unified packet format. IoTMap builds an iterative graph model where high-level semantics can progressively be deduced, ranging from packet transmission to application-type analysis. As such, IoTMap detects application behaviours amongst devices implementing different protocols, interconnected through a multi-protocol hub. In its current implementation (available at https://github.com/AlgoSecure/iotmap), IoTMap can inspect Zig- Bee, BLE and 6LowPAN networks

Audit d'un système IoT par test d'intrusion

National audienceL'explosion du secteur de l'Internet des Objets, reposant majoritairement sur des technologies de communication sans fil, soulève de nombreuses problématiques de sécurité. Ceci est notamment dû à leur caractère hétérogène, à leurs réseaux peu cloisonnés et une mise sur le marché hâtive. Nous proposons dans le cadre de cette thèse une méthode permettant d'évaluer la sécurité d'un système d'objets connectés utilisant des modes de communication sans fil, ceci afin de renforcer la sécurité du système d'information dans son ensemble. Notre méthodologie se base sur une approche éprouvée dans l'IT classique : le test d'intrusion

ADAM33, a New Candidate for Psoriasis Susceptibility

Psoriasis is a chronic skin disorder with multifactorial etiology. In a recent study, we reported results of a genome-wide scan on 46 French extended families presenting with plaque psoriasis. In addition to unambiguous linkage to the major susceptibility locus PSORS1 on Chromosome 6p21, we provided evidence for a susceptibility locus on Chromosome 20p13. To follow up this novel psoriasis susceptibility locus we used a family-based association test (FBAT) for an association scan over the 17 Mb candidate region. A total of 85 uncorrelated SNP markers located in 65 genes of the region were initially investigated in the same set of large families used for the genome wide search, which consisted of 295 nuclear families. When positive association was obtained for a SNP, candidate genes nearby were explored more in detail using a denser set of SNPs. Thus, the gene ADAM33 was found to be significantly associated with psoriasis in this family set (The best association was on a 3-SNP haplotype P = 0.00004, based on 1,000,000 permutations). This association was independent of PSORS1. ADAM33 has been previously associated with asthma, which demonstrates that immune system diseases may be controlled by common susceptibility genes with general effects on dermal inflammation and immunity. The identification of ADAM33 as a psoriasis susceptibility gene identified by positional cloning in an outbred population should provide insights into the pathogenesis and natural history of this common disease

Performance of the ATLAS electromagnetic calorimeter end-cap module 0

The construction and beam test results of the ATLAS electromagnetic end-cap calorimeter pre-production module 0 are presented. The stochastic term of the energy resolution is between 10% GeV^1/2 and 12.5% GeV^1/2 over the full pseudorapidity range. Position and angular resolutions are found to be in agreement with simulation. A global constant term of 0.6% is obtained in the pseudorapidity range 2.5 eta 3.2 (inner wheel)
