Advanced Threat Defense (ATD) 4.10 and later Intelligent Sandbox (IS) 5.x Problem
ATD/IS 4.10 introduced a new feature that receives external reputation from TIE. If TIE Enterprise Reputation is configured in ePolicy Orchestrator (ePO), the Threat Analysis Report shows the TIE Enterprise Reputation severity score. Currently, we support external reputation from Secure Web Gateway (SWG) and ATD/IS. If the file hashes were previously unseen in TIE Server and known malicious from ATD or SWG, TIE does the following:
Cause
If TIE Reputation is set for Medium, High, or Very High based on TIE File Reputation (ATD), we can't lower the severity to Very Low, Low, Information, or Clean. This behavior is as designed. To fix False-Positives caused due by this behavior, the ePO administrator must manually update TIE reputation for False-Positive samples. Solution
Since this issue is False-Positive due to TIE-ATD, you must update the TIE reputation for this sample to be fixed.
