    - link_events
      Events that can occur on a link, including being available or not.
    - links
      Links are protocol relations between two nodes with a specific protocol. They model the interaction between nodes.
    - node_cpe_changes
      When a Common Platform Enumeration (CPE) updates, it creates an entry in this query source to track software updates or to detect software.
    - node_cpes
