  - Scriptable protocols
    The Lua scripting API for building a custom protocol decoder.
  - Scriptable variables
    The scriptable variables correlation feature allows users to implement custom checks on the way variable values change over time. This section covers how such scripts can be implemented and used.

  - Data model reference
    The data model reference for query entities.
    - alerts
      A list of alerts that Guardian raises.
    - appliances
      This query source contains information about the sensors connected to the current CMC or Guardian.
    - assertions
      An assertion represents an automatic check against other query sources.
    - assets
      Assets represent a local, physical system, and can be composed of one or more nodes.
    - asset_cves
      View of Node Common Vulnerability and Exposures (CVE) grouped by CVE and asset.
    - captured_logs
      Logs captured passively over the network.
    - captured_urls
      URLs and other protocol calls found in the network. Access to files, requests to DNS, requested URLs and others are available in this query source.
    - function_codes
      Function codes used in the environment.
    - health_log
      Health-related events about the system - like high resource utilization or hardware-related issues or events.
    - 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
      Lists Common Platform Enumerations (CPEs), that is software or components connected to a specific node in the system.
    - node_cves
      Vulnerabilities are matched against current CVEs.
    - node_points
      Data points are polled via Smart Polling from monitored nodes.
    - nodes
      A list of nodes, where a node is an L2 or L3 or other entity able to speak some protocol.
    - report_files
      Generated reports available for consultation.
    - sessions_history
      Archived sessions.
    - sessions
      Live, mostly open, sessions between nodes. A session is a specific application-level connection between nodes. A link can hold one or more sessions at a given time.
    - variable_history
      History of values for variables, where history has been enabled.
    - variables
      Variables extracted via DPI from the monitored system.
