Splunk ES TA Change Log

Change Log

All notable changes to the Recorded Future Splunk ES add-on will be documented in this file.

[4.0.0] - 2018-10-23

New

  • Adaptive Response has been added.
    • The Adaptive Response can be added to any correlation search yielding supported IOC types (IP, domain, hash and URL). A new notable event will be created if the event can be enriched.
    • Ad-hoc mode is available (ex from the Incidents review panel), once used a drilldown link will open a panel with latest information about the IOC.
  • Added URL risk information.
  • Improved display of risk evidence in the Incident Review dashboard.
  • Support for Custom risklist using Recorded Future Fusion was added. Any number of risklists can be added.
  • Support for retreiving alerts from Recorded Future has been added.
  • Help pages are included in the app (including this Changelog).
  • New reports:
    • A new report "Latest updates of all risklists" was added.
    • A new report that show all log events from the app was added.
    • A new validation feature has been added. This feature can be used to verify that the app can work or to gather information about potential issues.
  • New options to customize access to Recorded Future's API (non-standard URL and optional SSL verification).
  • Search head cluster synchronization:
    • Only one cluster member retrieves risklists before distributing them to the rest of the cluster.
    • Configuration is synchronized, ex the API key can be added to any node in the cluster, it will be propagated to all nodes.

Changed

  • The filenames of the risklists in the the lookups folder have changed. Ex: rf_ip_threatfeed.csv has become rf_ip_risklist.csv. The transform used to map between the name and the file name has been adapted to ensure backwards compatibility.
  • Complete rewrite of the scripts included in the app.
    • Updates of the risklists and retreival of alerts have been implemented as modular inputs to improve reliability and scalability. Updates are performed as soon as new versions of the risklists become available.
    • The setup GUI has been extended and leverages Splunk's framework.
