Security Risk Assessment

Risk assessment is the key and core technologies ensuring IT system security. Based on the comprehensive analysis to complex information systems, this paper first summarizes the typical characters of complex information systems and then gives new risk factors that complex system need to face. Furthermore, a new risk assessment method is proposed to evaluate the complex information systems. The method takes full account of the effect of complexity of complex information systems in each process of risk assessment, and utilizes multi-level risk views to carry out in-depth analysis to the risk of complex system.

Security Risk Assessment

Based on the research of domestic and foreign vulnerability assessment systems, in this paper, we propose an improved network security assessment method based on Immunity algorithm. It integrates the advantages of both host based and network based scan system. Our goal is to explore the known security vulnerabilities, and to check hosts’ security effectively as well. It has the features of self-adaptive, distributed, and real time. Therefore, it provides a good solution to risk assessment for network security.
