Question 180
A risk review at a distributed branch estate focuses on preventing this issue again: A test policy group applies blocking to all unknown application traffic but is pushed to a shared branch scope without checking business application exceptions. Which recurring control is most suitable?
Explanation
Correct Answer
Stage profile rollout with representative service and threat-negative tests. This control reduces recurrence of the documented mechanism: An unreviewed global profile group can cause excessive blocking across multiple sites. It creates a repeatable check around the needed response: Validate matched applications and exceptions in a pilot scope, then publish the least-privilege profile group intentionally.
Incorrect Answers
Periodically review category actions against the organization's web-risk policy. That safeguard addresses another potential failure: A school wants malicious web categories blocked but keeps a URL Filtering profile action set to alert, causing allowed traffic to continue. It is not the most targeted recurring control for the described cause: An unreviewed global profile group can cause excessive blocking across multiple sites.
Regression-test representative file types and upload/download directions after profile edits. That safeguard addresses another potential failure: A remote office receives suspicious executable downloads while its file-blocking profile only prohibits compressed archives, not the executable type specified in policy. It is not the most targeted recurring control for the described cause: An unreviewed global profile group can cause excessive blocking across multiple sites.
Reconcile copied profiles with group membership before production deployment. That safeguard addresses another potential failure: An administrator clones a permissive antivirus profile into a strict production group but forgets to update the group's referenced member. It is not the most targeted recurring control for the described cause: An unreviewed global profile group can cause excessive blocking across multiple sites.
