Research On Classification Of Software Security Defects And Database Construction

Software security defects are inherent characteristics of software products, and they are inherent components. In the process of software development, software security defects are inevitable, the software security defects may occur in any stage of software development. These defects affect the quality of software, and also affect the progress of software development and cost. Therefore, IT sectors are dealing with the software security defects, at the same time, they realize the importance of prevention of defects. If we want to prevent security defects, first of all, we must do a good job in the classification of these defects. Orthogonal defect classification is just as the entry point for the prevention of defects. We could use this to analysis and classification the defects, and then take more comprehensive and specific measures for prevention.Orthogonal defect classification provides a measure of process, it makes the software security defects must be non-orthogonal overlap. In a large number of the classification techniques, orthogonal defect classification technology is more comprehensive. It provides a more sensitive means of measurement process. The type of orthogonal defect classification and the phase of software development are closely related, and it can give a correct explanation for the growth curve of different software security defects. Orthogonal defect classification is to classify the defect, and then link the software security defects and the process of the software development.Take orthogonal defect classification of software security defects as the basis for classification, because it provides a quantitative and qualitative analysis method. Orthogonal classification techniques can be used to measure the ability of software process, analysis the law of software security defects occurred, and measuring the validity of the verification process. At the same time, make a combination between the reliability of the traditional growth curve model and the type of the attributes of orthogonal defect classification, so that we can achieve the security of the software for more effective prevention of defects. This method is mainly used for analysis the data of software security defects, and it also can separate the defects which have been stabilized from which are still growing. The data of orthogonal defect classification of software security defects is the foundation of the process analysis. You can complete the analysis of the phenomenon of all defects. From a certain angle, the use of the method can speed up the project and reduce the cost of risk.The main line of software production is process, and a variety of activities surrounding the process. Orthogonal defect classification is precisely to provide a method of classification for the process of software security defect. To introduce the security defects is existed from needs analysis to system maintenance process. Orthogonal defect classification classifies the various phases of software security defects of software development. Based on the type of software made by the security classification of defects in the software production process to confirm the reproducibility of the defect, and then to find defects in the records of software security analysis. The last, we classified and summarized these software security defects. Orthogonal defect classification method can make a better understanding of the process of software security defects by basing on the process of software development.By the combination of orthogonal defect classification methods and the reliability growth curve model, through the reliability growth curve can reflect the trend of the defects in software security development. At the same time, we will divide the defects orthogonally. By using them, we could do a more detailed analysis of the software security defects. The combination of two methods, to make a comparison of the different types of software security defects in a coordinate system, which can do the qualitative analysis of the software security defects.In this paper, I research the software security defects mainly from two aspects. On the one hand, to analysis the program of classify, using orthogonal defect classification to classify the security defects, and combined with the reliability growth curve model. The combination of the two methods can do better qualitative analysis and quantitative analysis. On the other hand, I analysis the software security defects from the perspective of measurement, I analysis the "Core Business System of Insurance", and make a measurement and analysis. In the late development of the system, software security prevention of defects will provide a strong support.In addition, the article also makes a description about the database technology and design principles. I analyze the data model, the methods and techniques of database design. And I make the database entity-relationship diagram and data table structure based on the classification of software security defects and data flow diagram. I also discuss the design methodology and process of the database of software security defects.
