Summary

Trend Micro has received reports about an issue wherein the Trend Micro Apex One™ as a Service Behavior Monitoring Exception and the Trusted Program List do not deploy properly to endpoints. This may cause performance issues on endpoints since the exception list may not be applied correctly.

Trend Micro will deploy the fix for this on all provisions during the August 2021 maintenance. Please refer to this article for the monthly maintenance schedule and release notes.

Root Cause

This issue is caused by a logic error in processing the exception list whenever a program is removed from the list. When this issue is triggered, there would be leftover characters on the database that would cause the setting deployment to fail.

Workaround

Prior to the maintenance, you can perform the following actions to temporarily resolve the issue:

  1. Open the related policy and then go to the Behavior Monitoring settings > Exceptions tab.

    There is no need to perform any changes.

  2. Click save or deploy.

Recommendation

It is advised to apply the workaround if you suspect that the exception list is not properly deployed or if you have recently removed entries from the Behavior Monitoring Exception or Trusted Program List.
