Goal

Detect an Impossible Travel event when user performs a console login.

Strategy

The Impossible Travel detection type’s algorithm compares the GeoIP data of the last log and the current log to determine if the user with @userIdentity.session_name: {{@user.name}} traveled more than 500km at over 1,000km/h.

Triage and response

1. Determine if {{@user.name}} should be connecting from {{@impossible_travel.triggering_locations.first_location.city}}, {{@impossible_travel.triggering_locations.first_location.country}} and {{@impossible_travel.triggering_locations.second_location.city}}, {{@impossible_travel.triggering_locations.second_location.country}} in a short period of time.
2. If the user should not be connecting from {{@impossible_travel.triggering_locations.first_location.city}}, {{@impossible_travel.triggering_locations.first_location.country}} and {{@impossible_travel.triggering_locations.second_location.city}}, {{@impossible_travel.triggering_locations.second_location.country}}, then consider isolating the account and reset credentials.
