Allow TLS traffic between all devices and CrowdStrike cloud (again just need to have a ALLOW rule for TLS traffic from our environment to *.cloudsink.net, right?). The URL depends on which cloud your organization uses. We recommend that you use Google Chrome when logging into the Falcon environment. And once its installed, it will actually connect to our cloud and download some additional bits of information so that it can function properly. Fusion leverages the power of the Security Cloud and relevant contextual insights across endpoints, identities, workloads, in addition to telemetry from partner applications to ensure effective workflow automation. The cloud provisioning stage of the installation would not complete - error log indicated that sensor did connect to the cloud successfully, channel files were downloading fine, until a certain duration - task manager wouldn't register any network speed on provisioning service beyond that, and downloads would stop. Driven by the CrowdStrike Threat Graph data model, this IOA analysis recognizes behavioral patterns to detect new attacks, whether they use malware or not.
