Try in Splunk Security Cloud


Docker is an open source containerization platform. It helps programmers to bundle applications into containers, which are standardized executable parts that include the application source code along with the OS libraries and dependencies needed to run that code in any setting. The user can add mount the root directory into a container and edit the /etc/password file to add a super user. This requires the user to be privileged enough to run docker, i.e. being in the docker group or being root.

The SPL above uses the following Macros:

:information_source: linux_docker_privilege_escalation_filter is a empty macro by default. It allows the user to filter out any results (false positives) without editing the SPL.

Required fields

List of fields required to use this analytic.

  • _time
  • Processes.dest
  • Processes.user
  • Processes.parent_process_name
  • Processes.process_name
  • Processes.process
  • Processes.process_id
  • Processes.parent_process_id

How To Implement

To successfully implement this search, you need to be ingesting logs with the process name, parent process, and command-line executions from your endpoints into the Endpoint datamodel. If you are using Sysmon, you can use the Add-on for Linux Sysmon from Splunkbase.

Known False Positives

False positives are present based on automated tooling or system administrative usage. Filter as needed.

Associated Analytic Story


Risk Score Impact Confidence Message
5.0 10 50 An instance of $parent_process_name$ spawning $process_name$ was identified on endpoint $dest$

:information_source: The Risk Score is calculated by the following formula: Risk Score = (Impact * Confidence/100). Initial Confidence and Impact is set by the analytic author.
