This paper presents the current state of the art on attack and defense modeling approaches
that are based on directed acyclic graphs (DAGs). DAGs allow for a hierarchical …

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 …

Adapting the classifier trained on a source domain to recognize instances from a new target
domain is an important problem that is receiving recent attention. In this paper, we present …

Attack graphs are important tools for analyzing security vulnerabilities in enterprise
networks. Previous work on attack graphs has not provided an account of the scalability of …

The MITRE ATT&CK Framework provides a rich and actionable repository of adversarial
tactics, techniques, and procedures (TTP). However, this information would be highly useful …

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 …

This paper presents a novel model of intrusion analysis built by analysts, derived from years
of experience, asking the simple question,“What is the underlying method to our work?” The …

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 …

Cyber crime is a developing concern, where criminals are targeting valuable assets and
critical infrastructures within networked systems, causing a severe socio-economic impact …

This chapter describes CyGraph, a system for improving network security posture,
maintaining situational awareness in the face of cyberattacks, and focusing on protection of …
