Obviously, there is a need for automated information security analysis, validation, evaluation and testing approaches. Unfortunately, there is no state-of-art approach to carrying out information security evaluation in a systematic way. Information security evaluation of software-intensive and telecommunications systems typically relies heavily on the experience of the security professionals. Requirements are within the focus of the information security evaluation process. Information security requirements can be based on iterative risk, threat and vulnerability analyses, and technical and architectural information. There is a need for more practical ways to carry out this iterative process. In this paper we discuss security evaluation process, security objectives and security requirements from the basis of the experiences of a security testing project.
