Perceiving and understanding cyber-attacks can be a difficult task, and more effective
techniques are needed to aid cyber-attack perception. Attack modelling techniques (AMTs) …

Network security metrics (NSMs) based on models allow to quantitatively evaluate the
overall resilience of networked systems against attacks. For that reason, such metrics are of …

Attack graphs are a valuable tool to network defenders, illustrating paths an attacker can use
to gain access to a targeted network. Defenders can then focus their efforts on patching the …

Capturing the uncertain aspects in cyber security is important for security analysis in
enterprise networks. However, there has been insufficient effort in studying what modeling …

By accurately measuring risk for enterprise networks, attack graphs allow network defenders
to understand the most critical threats and select the most effective countermeasures. This …

There considerable advice in both research and practice oriented literature on the topic of
information security. Most of the discussion in literature focuses on how to prevent security …

By enabling a direct comparison of different security solutions with respect to their relative
effectiveness, a network security metric may provide quantifiable evidences to assist security …

A method and system for creating a composite security rating from security characterization
data of a third party computer system. The security characterization data is derived from …

Today's information systems face sophisticated attackers who combine multiple
vulnerabilities to penetrate networks with devastating impact. The overall security of an …

The cyber security modeling language (CySeMoL) is a modeling language for enterprise-
level system architectures coupled to a probabilistic inference engine. If the computer …
