Examination and Classification of Security Requirements of Software Systems

摘要: Currently, there exist different classifications of software requirements having direct impact on requirement engineering and analysis. These usually categorize into two classes functional non-functional requirements. Contrary to the requirements, are many methods tools supporting verification, analysis, design from early phases project. Since security vital in a system, their kind classification as or very important development secure systems. Current approaches, consider validation verification deferred until test phase. This causes weakness target system solving leaks costs much. Some approaches also develop an isolated process but it puts extra overhead non-standard decreases integrity In this paper, some major examined compared, finally, new is proposed.
