The risk assessment for network information system has experienced a stage from rule-based questionnaire investigation to model-based assessment. Many graph-based models have been proposed and applied to risk assessment. Attack Graph is widely used one. But attack graphs grow exponentially with the size of the network. In this paper, we propose a comprehensive framework for network vulnerabilities...
In order to assess the security of network information system, many graph-based approaches have been proposed. Attack Graph is the most influential one. But attack graphs grow exponentially with the size of the network. In this paper, we propose an improved access graph based model to analyze network security. As a complement to the attack graph approach, the access graph is host-centric approach,...

Protecting computer network security is critical today. Many graph-based approaches have been proposed to analyze network vulnerabilities. Attack Graph is the most influential one. But attack graphs grow exponentially with the size of the network. In this paper, we propose a comprehensive framework for network vulnerabilities modeling and analysis based on the access graph. As a complement to the...
Going beyond vulnerability scanning tools that make lists of known vulnerabilities locating on given individual hosts, attack graphs identify all possible attack paths that end in a state where an attacker has successfully achieved his goal. But the algorithmic complexity grows exponential in the size of the network. The access graph is proposed as a complement to the attack graph approach which is...
