Semi-Automated Cyber Threat Intelligence (ACT)

The main objective of the research project is to develop a platform for cyber threat intelligence to uncover cyberattacks, cyber espionage and sabotage.

The project will result in new methods for data enrichment and data analysis to enable identification of threat agents, their motives, resources and attack methodologies.

In addition, the project will develop new methods, work processes and mechanisms for the generation and distribution of threat intelligence and countermeasures, to stop ongoing and prevent future attacks.

Platform Architecture – Graph database

•Looked into existing graph databases, butthey lacked proper fine granular permissions(and many of them had commercial licensesthat could not be used in the researchproject)

•Apache Tinkerpop implemented on top ofCassandra/Elasticsearch

•Graph queries opens up a range ofpossibilites that is not possible on a flat data structure
