Data Gathering - detected between Brain and Sensor

Vectra detected data gathering between the brain and the sensor, triggering an alert.

Problem

Vectra detected data gathering between the brain and the sensor communication during the upgrade process and triggering an alert as "Data gathering: Exfiltration".

Root Cause

The exchange of information between the brain and the sensor is a standard procedure during updates. However, as per the product design and transparency, we let customers understand fully what's going on in their network (even if it's our own product) and make informed decisions about how to handle that. If the customer does not want to trigger the detection, we request customer to create a triage filter that would normally prevent such alerts during the upgrade process.

Solution

We need to create a Triage Filter for Brain and Sensor communication. For that:

• Login to the Vectra portal
• Navigate to detection where you found the Vectra Sensor and the Brain communication is identified as "Data gathering"
• Select the detection > Triage
• Create a filter to exclude brain/sensor or sensor/sensor communication during updates.
