The sample configuration profile given above is subject to OS or application updates. It is recommended to verify the configuration profile on the targeted OS versions using third-party profile editors before deploying it in bulk.

What happens once the policy is associated?

After associating the policy with the device, the following processes are initiated, depending on the configurations specified in the policy.

  1. The CrowdStrike sensor PKG gets installed on the device, consisting of two apps: the Crowdstrike agent app and the Crowdstrike sensor app.
  2. The system extensions and kernel extensions configurations allocate the necessary permissions to the applications accordingly.
  3. The Crowdstrike agent and Crowdstrike sensor apps are granted Full Disk Access. The apps may or may not appear in list under Privacy & Security > Full Disk Access with the toggle button on/off on the device end. Rest assured that the permissions have been successfully granted to them.
  4. Third-party Plugin web content filtering and Notification Settings are configured.
