Endpoints can start to generate more Windows Event Viewer event codes 5152 and5157 which are related to WFP filter after being upgraded to the 4.0.2.1540 sensor version.
The CB Cloud Windows sensor has used WFP for many versions and there are some new blocks/detections that are taking advantage of this feature in 4.0.2.1540.
This is normal and expected behavior for the CB Cloud Windows sensor 4.0.2.1540 version.
