Book excerpt: Les drones sont de plus en plus présents, dans nos vies pour le loisir comme dans l'industrie. Les prévisions sur le marché des drones civils envisagent une croissance importante sur les prochaines années et pourrait atteindre 10 à 20 milliards d'euros au niveau mondial.Si les missions confiées aux drones ont tout d'abord considéré des drones isolés, certains types de missions nécessitent la collaboration de plusieurs d'entre eux au sein d'une flotte.Une flotte de drones nécessite la mise en œuvre et la disponibilité d'un réseau sans fil pour toute les tâches ayant trait d'une part à la mission et d'autre part à toute coordination ou synchronisation. Les réseaux sans fil sont par nature ouverts sur l'extérieur et il se pose donc la question de leur sécurisation. Plusieurs travaux de recherche ont abordé cette question avec différents angles d'attaque : la couche physique, les protocoles de routage, les systèmes multi agents. Mais aucun n'aborde la question de la sécurisation de l'accès à ce réseau et peu ont étudié la question des réponses à apporter en cas d'attaque.Dans cette thèse nous proposons une architecture orientée vers la sécurité permettant une meilleure maîtrise des communications dans le réseau, et s'affranchissant entièrement de toute infrastructure fixe au sol. Cette architecture allie les réseaux définis par logiciels (SDN), qui est une technologie qui a émergé récemment, avec AODV, un protocole de routage adapté aux réseaux ad hoc de type FANET. Nous démontrons que cette architecture permet de protéger le réseau contre la plupart des attaques depuis l'extérieur. Cette architecture nous permet également d'obtenir une bonne connaissance de l'activité dans le réseau, pré-requis pour améliorer la sécurité.De cette connaissance, nous proposons d'une part une technique de détection d'injection de trafic depuis l'extérieur et une méthode pour s'en défendre. D'autre part, nous proposons un ensemble de caractéristiques mesurables de l'activité du réseau propres à être utilisées avec un algorithme d'apprentissage automatique.Nous démontrons la pertinence de ces mesures en entraînant un modèle de classification par apprentissage supervisé de type Random Forest sur un ensemble de captures réseaux présentant des attaques sur le réseau: déni de service (DoS), balayage de ports, découverte de mot de passe (brute force) et déni de service distribué (DDoS). Les performances en terme de détection d'attaques basées sur ces caractéristiques sont prometteuses, non seulement en terme de précision mais également en terme de vitesse de détection, offrant ainsi la possibilité d'une réaction en temps réel. Cette réaction peut être mise en œuvre grâce à l'architecture proposée dans cette thèse. Des tests sur des scénarios représentatifs d'un trafic réseau pour une flotte de drones montrent que le modèle est capable de généraliser avec de bonnes performances sur notre cas d'étude.

Download or read book City of Man written by Michael Gerson and published by Moody Publishers. This book was released on 2010-10-01 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: An era has ended. The political expression that most galvanized evangelicals during the past quarter-century, the Religious Right, is fading. What's ahead is unclear. Millions of faith-based voters still exist, and they continue to care deeply about hot-button issues like abortion and gay marriage, but the shape of their future political engagement remains to be formed. Into this uncertainty, former White House insiders Michael Gerson and Peter Wehner seek to call evangelicals toward a new kind of political engagement -- a kind that is better both for the church and the country, a kind that cannot be co-opted by either political party, a kind that avoids the historic mistakes of both the Religious Left and the Religious Right. Incisive, bold, and marked equally by pragmatism and idealism, Gerson and Wehner's new book has the potential to chart a new political future not just for values voters, but for the nation as a whole.

Book Synopsis Kurt Meyer on Trial by : P. Whitney Lackenbauer
Download or read book Kurt Meyer on Trial written by P. Whitney Lackenbauer and published by . This book was released on 2007 with total page 697 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In late 1945, a Canadian military court sitting in occupied Germany convicted Waffen-SS General Kurt Meyer on charges related to the murder of Canadian prisoners of war in Normandy. It was Canada's first entry into the war crimes field and the trial raised several important operational and legal issues, particularly with regard to command responsibility. Although sentenced to death by firing squad, Meyer was saved by the controversial decision of Canadian military authorities to commute the sentence and was released after less than a decade of imprisonment in New Brunswick and West Germany. Meyer's war crimes trial and the final result caused consternation and outrage among the Canadian public at the time. It remains among the most contentious episodes in Canadian military history. This collection brings together previously unpublished documents related to Canada's prosecution of Kurt Meyer, including the original trial transcript and selected materials to situate the trial in its political, military, diplomatic and legal context" -- p.
