Objects based systems are presents everywhere in our life. When such a system presents vulnerabilities, confidentiality and integrity are thus widely compromised. For example, Java is an object language authorizing many cyber-attacks between 2012 and 2013 leading the US department of homeland security to recommend its abandon. This thesis proposes to limit the relations between the objects thanks to a mandatory access control. First, a general model of objects supporting objects and prototypes languages is defined. Second, the elementary relations are formalized in order to control them. Those relations include the reference, interaction and three types of flow (activity, information and data). Automata authorize a logic that enables to compute the required mandatory policy. At the same time, the computation of the MAC policy and the efficiency are solved since the policy is reduced. Experimentations use the JAAS security objectives existing in the Java language. Thus, one year of Java vulnerabilities is prevented thanks to the Metasploit framework. ; Les systèmes à objets sont présents partout dans notre quotidien. Ainsi, une vulnérabilité dans ces systèmes compromet amplement la confidentialité ou l'intégrité. Par exemple, Java est un système à objets basé sur les classes qui a été la cible de nombreuses cyber-attaques entre 2012 et 2013 au point que le département de la sécurité intérieure des Etats-Unis recommande son abandon. Dans cette thèse nous proposons de limiter les relations entre objets au moyen d'un contrôle d'accès obligatoire. Pour cela nous définissons un modèle général de système à objets supportant notamment les langages objets et à prototypes. Puis nous formalisons les relations élémentaires que nous pouvons observer et donc contrôler. Celles-ci sont la référence, l'interaction et trois types de flux (d'activité, d'information, de données). Nous proposons également une logique basée sur des automates qui permet de calculer les privilèges de chaque objet. Ainsi, nous calculons dynamiquement la politique obligatoire nécessaire pour satisfaire les objectifs de sécurité exigés. Par là même, nous résolvons d'un seul coup le calcul des politiques obligatoires et le problème d'efficacité puisque la politique obligatoire se trouve réduite. L'expérimentation propose une application aux objectifs de sécurité JAAS existants dans Java. De fait, nous avons été capables d'empêcher les malwares Java correspondant à une année de vulnérabilités au moyen de l'outil d'exploitation Metasploit.

In this article, we examine how to give objects a voice in organizational narrative. We track our encounter with a 914 Xerox copier, a redundant technological object that was scripted into a desired historical narrative within a corporate exhibit. Despite the 914's apparent mnemonic and institutional efficacy, we questioned whether it might constitute more than a narrative repository. Might material objects in organizations also participate in narrative production? In this article, we advocate a post-social approach to narrative methodology that recognizes objects—such as the 914—as non-human actors in organizational sense-making. After reviewing post-sociality's central premises, we propose three domains through which an object narrative can be elicited: object materiality, object practices and object biography. First, we suggest that object materiality can highlight the significant, networks of forces, materials and people—and therefore episodes and actors—that engage with and through objects. Second, we argue that people and objects are enmeshed in sequenced, workplace activities, and therefore through object practice humans define what stories objects can tell while objects reciprocally influence the latitude of human performance. Third, we propose that object biography provides a strategy to map the connections and transitions that occur over the life-course of an object, which can, in turn, unravel a changing web of organizational relations. Our aim is to provide methodological guidance to narrative researchers seeking to augment their organizational analyses by scrutinizing human–object enmeshment.

La pandemia del coronavirus provocó una incertidumbre generalizada, al extremo de haber paralizado el aparato productivo a escala planetaria. Pocas veces el capitalismo ha experimentado una crisis tan compleja. Luego de dos años de emergencia sanitaria, todavía no se sabe a ciencia cierta cuál es la situación real y la evolución posible de la pandemia. Al contrario de lo que pregonan los devotos del neoliberalismo, el fin de la historia terminó siendo la metáfora de la inviabilidad del capitalismo. Las respuestas han sido diversas, pero desde los poderes globales se busca aprovechar la crisis para incrementar el control sobre la sociedad. Desde las lógicas comunitarias, en cambio, se intenta responder con alternativas más colectivas, solidarias e incluso ancestrales, como ocurrió con el manejo de la pandemia. La mayor amenaza es la utilización del miedo para incrementar no solo los mecanismos de biovigilancia de la gente, sino el control individualizado de toda la población. El desarrollo de la genética, acelerado a partir del combate al coronavirus, potencia las posibilidades de actuar desde la política sobre la estructura genética de las personas. Frente a esta amenaza, los pueblos del mundo tienen la opción de potenciar su resistencia desde la diversidad cultural. Las gigantescas movilizaciones de 2019 expusieron una multiplicidad de agendas e identidades tan amplia que se vuelven incontrolables desde la centralidad del poder. El capitalismo puede ser sitiado desde una enorme variedad de posiciones que intervengan en forma simultánea. ; The coronavirus pandemic causes widespread uncertainty, to the point of paralyzing productive apparatus on a planetary scale. Rarely has capitalism experienced such a complex crisis. After two years of sanitary emergency, the real situation and the possible evolution of the pandemic are still uncertain. Contrary to what the devotees of neoliberalism proclaim, the end of history is finally the metaphor of the unviability of capitalism. The answers have been diverse, but global powers have sought to take advantage of the crisis to increase their control over society. On the other hand, community logics have tried to respond with more collective, solidarity-based and even ancestral alternatives, as was the case with the management of pandemic. The greatest threat is the use of fear to increase not only the mechanism of bio-surveillance of people, but also the individualized control of the entire population. The development of genetics, accelerated by the fight against coronavirus, enhances the possibilities of political action over genetic structure of people. Face to this threat, peoples around the world have the option of empowering their resistance from cultural diversity. The enormous mobilizations in 2019 exposed a multiplicity of agendas and identities, so wide that they become uncontrollable from the centrality of power. Capitalism can be besieged from a great variety of positions that intervene simultaneously. ; A pandemia do coronavírus causou incerteza generalizada, a ponto de paralisar o aparato produtivo em escala planetária.

O capitalismo pode ser assediado por uma enorme variedade de posições que intervêm simultaneamente.

In addition to the technical and managerial problems intrinsic to the control process in a diverse and complex multinational structure like the EC, there is also the problem of sectional interest. Control could be improved by the development of more joint funding programmes which give member states a direct financial stake in projects. But experience from federal systems cautions against too much optimism here. An alternative route is to improve enforcement through better management. (SJK)

This article reveals the socio-psychological essence of the social determinants of typical syndromes of social work objects. It analyzes the possibilities of a socio-psychological approach to understanding the nature of these phenomena. It reveals such concepts as quality of life, typical negative socio-psychological phenomena, including social maladjustment, socially stressful situation, social fears and other phenomena. It also examines the practice of overcoming socially destructive phenomena, in particular, fears.
