This book provides readers insights into cyber maneuvering or adaptive and intelligent cyber defense. It describes the required models and security supporting functions that enable the analysis of potential threats, detection of attacks, and implementation of countermeasures while expending attacker resources and preserving user experience. This book not only presents significant education-oriented content, but uses advanced content to reveal a blueprint for helping network security professionals design and implement a secure Software-Defined Infrastructure (SDI) for cloud networking environments. These solutions are a less intrusive alternative to security countermeasures taken at the host level and offer centralized control of the distributed network. The concepts, techniques, and strategies discussed in this book are ideal for students, educators, and security practitioners looking for a clear and concise text to avant-garde cyber security installations or simply to use as a reference. Hand-on labs and lecture slides are located at http://virtualnetworksecurity.thothlab.com/. Features Discusses virtual network security concepts Considers proactive security using moving target defense　 Reviews attack representation models based on attack graphs and attack trees Examines service function chaining in virtual networks with security considerations Recognizes machine learning and AI in network security.

In IPv6 networks, hosts can have multiple IPv6 addresses per interface and have multiple interfaces. This means that the applications or the kernel must be able to select the right source address, especially when the network services can be linked to this source address. The IETF (Apple, Cisco and Google) are developing 'provisioning domains' to this effect, Cisco has put in the open source community Linux kernel patches to allow applications to select such 'provisioning domains'.

The goal of this Master thesis is to analyse the best ways for applications to select the provisioning domains (whether there is a human interaction or not), and write libraries and at least modify one interactive application exploiting this feature. The development must be done in Linux. Knowledge in Linux kernel development is required.

Quatrième de couverture : "De plus en plus souvent l'information journalistique arrive directement sur les "murs" de nos réseaux sociaux, en priorité Facebook ou Twitter, mais aussi LinkedIn ou Snapchat et bien sûr via des vidéos mises en ligne sur YouTube ou DailyMotion. La médiation de ces plateformes pour accéder à l'information d'actualité n'est pas neutre. L'objet de ce livre est d'essayer de comprendre ce qui change dans notre rapport aux médias, notre relation à l'information dès lors que se met petit à petit en place un nouvel écosystème de l'information à l'ère des réseaux socionumériques. Que partage-t-on ? Comment le faisons-nous ? Comment commentons-nous l'actualité sur Twitter ou Facebook ? Quels nouveaux usages, quels arts de faire les internautes mettent-ils en oeuvre pour utiliser les dispositifs offerts par ces plateformes : hashtags, like, retweet, emojis et émoticônes... A l'heure des fake news, des risques d'enfermement dans des "bulles de filtre" via les recommandations de nos "amis" et des algorithmes, il est indispensable, pour le bon fonctionnement de nos démocraties, de prendre pleinement conscience du bouleversement qui se joue sous nos yeux, dans nos pratiques quotidiennes d'information."

A new, counterintuitive theory for how social networks influence the spread of behaviorNew social movements, technologies, and public-health initiatives often struggle to take off, yet many diseases disperse rapidly without issue. Can the lessons learned from the viral diffusion of diseases be used to improve the spread of beneficial behaviors and innovations? In How Behavior Spreads, Damon Centola presents over a decade of original research examining how changes in societal behavior--in voting, health, technology, and finance-occur and the ways social networks can be used to influence how they propagate. Centola's startling findings show that the same conditions accelerating the viral expansion of an epidemic unexpectedly inhibit the spread of behaviors. While it is commonly believed that "weak ties"-long-distance connections linking acquaintances-lead to the quicker spread of behaviors, in fact the exact opposite holds true. Centola demonstrates how the most well-known, intuitive ideas about social networks have caused past diffusion efforts to fail, and how such efforts might succeed in the future. Pioneering the use of Web-based methods to understand how changes in people's social networks alter their behaviors, Centola illustrates the ways in which these insights can be applied to solve countless problems of organizational change, cultural evolution, and social innovation. His findings offer important lessons for public health workers, entrepreneurs, and activists looking to harness networks for social change.Practical and informative, How Behavior Spreads is a must-read for anyone interested in how the theory of social networks can transform our world.
