Die Sicherheit einer IT-Komponente hängt meist direkt von einer oder mehreren anderen Komponenten ab, wobei diese Abhängigkeiten komplex und schwer erfassbar sind. In diesem Buch wird das Thema Sicherheit daher systematisch betrachtet: Lösungen für immer wiederkehrende Sicherheitsprobleme werden erstmals in Form von "Security Patterns" dargestellt. Die Grundlage hierfür bilden langjährige Erfahrungen, die im Rahmen ...

Knowledge of number theory and abstract algebra are pre-requisites for any engineer designing a secure internet-based system. However, most of the books currently available on the subject are aimed at practitioners who just want to know how the various tools available on the market work and what level of security they impart. The definitive text on security and cryptography courses, Internet Security differs by its assertion that cryptography is ...

In this new approach, the authors consider the data network as a channel (in the sense of information theory) with several layers. The suggested "global" approach to coding in a network is consequently connected with other network procedures, such as protocols, and this determines complexity and originality of the problems of coding within the network. The authors distinguish different coding processes at three network layers (data link layer, ...
