VIEW RULE IN DATADOG VIEW SIGNALS

Set up the forcepoint-security-service-edge integration.

Goal

Identify instances where users are performing activities on Forcepoint SSE from geographically distant locations within an improbable time frame, potentially indicating credential theft or account compromise.

Strategy

This rule analyzes Forcepoint SSE to identify cases where a user appears to perform actions from two different countries or cities within a time frame that would make physical travel between those locations impossible.

Triage and Response

1. Review the events and identify the user {{@usr.name}} associated with the impossible travel behavior.
2. Determine if this user has triggered similar alerts in the past or exhibited unusual activity patterns recently.
3. If suspicious behavior is confirmed, restrict access for {{@usr.name}}, reset the account’s credentials, and notify the user.
