Playbook Series: Unauthorized IP Alert from a Mobile Device

Today’s post continues an ongoing series on Playbooks; which Phantom uses to automate and orchestrate your security operations plan.

Playbooks are Python scripts that Phantom interprets in order to execute your mission when you see something that you want to take action on. Playbooks hook into the Phantom platform and all of its capabilities in order to execute actions, ensuring a repeatable and auditable process around your security operations.  Sample community Playbooks can be customized at will and are synchronized via Git and published on our public Community GitHub repository.   You can read more about Phantom and Playbooks here.

The spotlight Playbook for today relates to an unauthorized IP alert.  In this use case, it occurs when a mobile device attempts to access an unauthorized site, where authorization is defined via an access list.  This policy violation is an indication of a possible insider threat.

In this scenario, the user is a repeat offender, so the action is perhaps a bit aggressive, but warranted.  As the diagram shows, the devices is wiped and then blocked.  This is a precautionary step taken in case the user is preventing the wipe command from reaching the mobile device.

The use case starts with an event logged to Splunk which in turn triggers Phantom to orchestrate the following actions automatically:

  • Pull the device and user profile from the MDM and directory systems.
  • Wipe the phone via the MDM system and block it at the firewall.
  • Open a ticket for further investigation by the security team who can retrieve the mobile device and perform the required forensics.

The savings are substantial for an organization that sees even an average volume of events.   You can read more about the ROI of Automation & Orchestration here.
