AI - Using natural language processing of open sources for building a security knowledge base

The paper describes the capabilities of building a security knowledge base as an important element in the implementation of Cyber Threat Intelligence. Described options will be backed by PoC outputs and real-life demonstrations.

Frequent problem of companies and our customers is the lack of cyber security staff. One approach to addressing this shortcoming is to build an intelligent knowledge base. This knowledge base must be focused on the Cyber Threat Intelligence field and domain. Presetnation will decribe the following phases:

  1. Collect relevant data using OSINT access. Data collection from websites, discussion forums, twitter and other sources where security threats and incidents are described.
  2. Analysis of threat descriptions. The descriptions are in most cases described in semi-structured form. At this stage, descriptions are analysed by a system that has natural language processing capabilities.
  3. Making the knowledge base available to analysts in the form of a well structured environment with analytical capabilities.
