This document discusses security engineering patterns for building secure network and application architectures. It notes that while digital business requires security, the increasing occurrence of severe attacks shows that more time and effort is still needed to develop secure systems. The document was written by two researchers from the Darmstadt University of Technology's Department of Computer Science and focuses on introducing security patterns to help address ongoing security issues.

Abstract
Conducting digital business requires secure network and application architectures. The recently increasing
occurrence of severe attacks has shown, however, that we will still
