Security tactics selection poker (TaSPeR): a card game to select security tactics to satisfy security requirements. Towards a reliable mapping between performance and security tactics, and architectural patterns. Despite the best intentions of software architects, it is often the case that individual developers do not faithfully implement the original security design decisions. Software architecture design tactics are high level design decisions. Consequently, flaws in the implementation of security tactics or their deterioration during software evolution and maintenance can introduce severe vulnerabilities that could be exploited by attackers. Software architecture has become a widely accepted conceptual basis for the development of nontrivial software in all application areas and by organizations of all sizes.
