Gestion des risques appliquée aux systèmes d’information distribués / Risk management to distributed information systems

Lalanne, Vincent 19 December 2013 (has links)
Dans cette thèse nous abordons la gestion des risques appliquée aux systèmes d’information distribués. Nous traitons des problèmes d’interopérabilité et de sécurisation des échanges dans les systèmes DRM et nous proposons la mise en place de ce système pour l’entreprise: il doit nous permettre de distribuer des contenus auto-protégés. Ensuite nous présentons la participation à la création d’une entreprise innovante qui met en avant la sécurité de l’information, avec en particulier la gestion des risques au travers de la norme ISO/IEC 27005:2011. Nous présentons les risques liés à l’utilisation de services avec un accent tout particulier sur les risques autres que les risques technologiques; nous abordons les risques inhérents au cloud (défaillance d’un provider, etc...) mais également les aspects plus sournois d’espionnage et d’intrusion dans les données personnelles (Affaire PRISM en juin 2013). Dans la dernière partie nous présentons un concept de DRM d’Entreprise qui utilise les métadonnées pour déployer des contextes dans les modèles de contrôle d’usage. Nous proposons une ébauche de formalisation des métadonnées nécessaires à la mise en œuvre de la politique de sécurité et nous garantissons le respect de la réglementation et de la loi en vigueur. / In this thesis we discuss the application of risk management to distributed information systems. We handle problems of interoperability and securisation of the exchanges within DRM systems and we propose the implementation of this system for the company: it needs to permit the distribution of self-protected contents. We then present the (our) participation in the creation of an innovative company which emphasizes on the security of information, in particular the management of risks through the ISO/IEC 27005:2011 standard. We present risks related to the use of services, highlighting in particular the ones which are not technological: we approach inheritent risks in clouds (provider failure, etc ...) but also the more insidious aspects of espionage and intrusion in personal data (Case PRISM in June 2013). In the last section, we present a concept of a DRM company which uses metadata to deploy settings in usage control models. We propose a draft formalization of metadata necessary for the implementation of a security policy and guarantee respect of regulations and legislation.

Informačná bezpečnosť a riadenie rizík v konkrétnej spoločnosti / Information security and risk management in a particular company.

Slávková, Daniela January 2012 (has links)
The aim of the thesis is to apply the methodology of qualitative risk analysis according to ISO/EC/27005:2011 and to increase awareness of existing threats and impacts on information assets and to create possible security precautions to minimize identified threats in a particular company. The thesis is divided into five chapters. Introductory chapter explains the basic concepts of information security and risk management in the organization that are necessary for understanding of the principles and the importance of information security. The second chapter deals with the international standards aimed at information security and briefly describes ISO/IEC 27001, ISO/IEC 27002 and ISO/IEC 27005. The following two chapters form a smooth transition from the theoretical to the practical part. The third chapter characterizes selected company and describes the current state of information security in the company. The fourth chapter forms the methodological apparatus of qualitative risk analysis, compiled in accordance with ISO/IEC 27005:2011. It also contains a list of relevant threats, to which an asset of the company is exposed. The last chapter is conducted to qualitative risk analysis, together with the draft of the precautions to minimize the risks. The practical section shows that by the implementing the proposed action the company will reduce existing risks to acceptable levels and will significantly improve the protection of information assets.
