Security Information Fusion System has recently become one of the major topics in the research area of information security. A great deal of security devices and components have been deployed in network information systems. While improving the systems security performance, they produced lots of redundant or unreliable information. Through the technologies of alert fusion and correlation analysis,...
Traditional network security assessment technologies are usually qualitative analyses from large variation of security factors. It is difficult to guide security managers to configure network security mechanisms. A new network security quantitative analysis method called ACRL is presented in this paper. It assesses attack sequences from credibility, risk and the loss of system and provides the assessment...
Digital control systems are essential to the safe and efficient operation of a variety of industrial processes in sectors such as electric power, oil and gas, water treatment, and manufacturing. Modern control systems are increasingly connected to other control systems as well as to corporate systems. They are also increasingly adopting networking technology and system and application software from...
As the rapid increase of network security events, network security monitoring and management on network behavior become more and more focused in the fields of computer science. This paper develops a kind of fuzzy constraint correlation algorithm based on prerequisites and consequences of security event. The introduction of fuzzy constraint correlation can resolve the issues of false negatives and...
Intrusion Detection and Response Systems have become a core component in modern security architectures. Current researches are combining intrusion detection and response systems with risk analysis or cost-sensitive approaches to enhance the detection and the response procedure, by assessing the risk of detected attacks and candidate countermeasures. The Risk has two primary dimensions: (i) the likelihood...
