Software security assurance of telecommunication systems

In order to obtain evidence about the security strength or performance in software products and telecommunication systems we need automated information security analysis, validation, evaluation and testing approaches. Unfortunately, no widely accepted practical approaches are available. Information security testing of software-intensive and telecommunications systems typically relies heavily on the experience of the security professionals. In this study, we argue that security requirements are within the focus of the information security testing process. Information security requirements can be based on iterative risk, threat and vulnerability analyses, and technical and architectural information. We discuss security testing process, security objectives and security requirements from the basis of the experiences of a security testing case study project.
