Query: A System for Automated Open-Source Threat Intelligence Gathering and
  Management   To remain aware of the fast-evolving cyber threat landscape, open-source
Cyber Threat Intelligence (OSCTI) has received growing attention from the
community. Commonly, knowledge about threats is presented in a vast number of
OSCTI reports. Despite the pressing need for high-quality OSCTI, existing OSCTI
gathering and management platforms, however, have primarily focused on
isolated, low-level Indicators of Compromise. On the other hand, higher-level
concepts (e.g., adversary tactics, techniques, and procedures) and their
relationships have been overlooked, which contain essential knowledge about
threat behaviors that is critical to uncovering the complete threat scenario.
To bridge the gap, we propose SecurityKG, a system for automated OSCTI
gathering and management. SecurityKG collects OSCTI reports from various
sources, uses a combination of AI and NLP techniques to extract high-fidelity
knowledge about threat behaviors, and constructs a security knowledge graph.
SecurityKG also provides a UI that supports various types of interactivity to
facilitate knowledge graph exploration.
