Evaluation of computer network security using attack undirected geography

Evaluation of Computer Network Security based on Attack Graphs and Security Event Processing

The paper is devoted to the security assessment problem. Authors suggest an approach to the security assessment based on the attack graphs that can be implemented in contemporary Security Information and Event Management (SIEM) systems. Key feature of the approach consists in the application of the developed security metrics system based on the differentiation of the input data for the metrics ...

Attack Graph Based Evaluation of Network Security

The perspective directions in evaluating network security are simulating possible malefactor’s actions, building the representation of these actions as attack graphs (trees, nets), the subsequent checking of various properties of these graphs, and determining security metrics which can explain possible ways to increase security level. The paper suggests a new approach to security evaluation bas...

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

Measuring the Overall Security of Network Configurations Using Attack Graphs

Today’s computer systems face sophisticated intrusions during which multiple vulnerabilities can be combined for reaching an attack goal. The overall security of a network system cannot simply be determined based on the number of vulnerabilities. To quantitatively assess the security of networked systems, one must first understand which and how vulnerabilities can be combined for an attack. Suc...
