description: 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.

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.
