Scenario Graphs Applied to Network Security

چکیده

Traditional model checking produces one counterexample to illustrate a violation of a property by a model of the system. Some applications benefit from having all counterexamples, not just one. We call this set of counterexamples a scenario graph. In this chapter we present two different algorithms for producing scenario graphs and explain how scenario graphs are a natural representation for attack graphs used in the security community. Through a detailed concrete example, we show how we can model a computer network and generate and analyze attack graphs automatically. The attack graph we produce for a network model shows all ways in which an intruder can violate a given desired security property.

An Ant Colony Optimization Algorithm for Network Vulnerability Analysis

Intruders often combine exploits against multiple vulnerabilities in order to break into the system. Each attack scenario is a sequence of exploits launched by an intruder that leads to an undesirable state such as access to a database, service disruption, etc. The collection of possible attack scenarios in a computer network can be represented by a directed graph, called network attack gra...

A particle swarm optimization algorithm for minimization analysis of cost-sensitive attack graphs

To prevent an exploit, the security analyst must implement a suitable countermeasure. In this paper, we consider cost-sensitive attack graphs (CAGs) for network vulnerability analysis. In these attack graphs, a weight is assigned to each countermeasure to represent the cost of its implementation. There may be multiple countermeasures with different weights for preventing a single exploit. Also,...

A survey on impact of cloud computing security challenges on NFV infrastructure and risks mitigation solutions

Increased broadband data rate for end users and the cost of resource provisioning to an agreed SLA in telecom service providers, are forcing operators in order to adhere to employment Virtual Network Functions (VNF) in an NFV solution. The newly 5G mobile telecom technology is also based on NFV and Software Define Network (SDN) which inherit opportunities and threats of such constructs. Thus a ...

A Novel Attack Graph Posterior Inference Model Based on Bayesian Network

Network attack graphs are originally used to evaluate what the worst security state is when a concerned network is under attack. Combined with intrusion evidence such like IDS alerts, attack graphs can be further used to perform security state posterior inference (i.e. inference based on observation experience). In this area, Bayesian network is an ideal mathematic tool, however it can not be d...

Scenario Graphs and Attack Graphs: a Summary

For the past twenty years, model checking has been used successfully in many engineering projects. Model checkers assist the engineer in identifying automatically individual design flaws in a system. A typical model checker takes as input a model of the system and a correctness specification. It checks the model against the specification for erroneous behavior. If erroneous behavior exists, the...
