• Authors: Sònia Leal Díaz, Sergio Pastrana, Azqa Nadeem,
• Abstract summary: This paper proposes a querying and prioritization-enabled visual analytics dashboard for SAGE. We describe the utility of the proposed dashboard using intrusion alerts collected from a distributed multi-stage team-based attack scenario. We find that the dashboard is useful in depicting attacker strategies and attack progression, but can be improved in terms of usability.

• Abstract: Although intrusion alerts can provide threat intelligence regarding attacker strategies, extracting such intelligence via existing tools is expensive and time-consuming. Earlier work has proposed SAGE, which generates attack graphs from intrusion alerts using unsupervised sequential machine learning. This paper proposes a querying and prioritization-enabled visual analytics dashboard for SAGE. The dashboard has three main components: (i) a Graph Explorer that presents a global view of all attacker strategies, (ii) a Timeline Viewer that correlates attacker actions chronologically, and (iii) a Recommender Matrix that highlights prevalent critical alerts via a MITRE ATT&CK-inspired attack stage matrix. We describe the utility of the proposed dashboard using intrusion alerts collected from a distributed multi-stage team-based attack scenario. We evaluate the utility of the dashboard through a user study. Based on the responses of a small set of security practitioners, we find that the dashboard is useful in depicting attacker strategies and attack progression, but can be improved in terms of usability.

  This paper builds an action forecasting capability on top of the alert-driven AG framework for predicting the next likely attacker action. We also modify the framework to build AGs in real time, as new alerts are triggered. This way, we convert alert-driven AGs into an early warning system that enables analysts circumvent ongoing attacks and break the cyber killchain.
