Configuring external device control policies

The external device control policies offered by DataSecurity Plus help restrict read, write, or execute actions on USBs—either individually or all together—to ensure that sensitive data does not leave the organization and to prevent the infiltration of malware. This policy can also prevent file transfers by blocking peripheral devices operating on Bluetooth and Wi-Fi, and CD or DVD drives.

Steps to create a new external device control policy:

  • Select Endpoint DLP from the application drop-down at the top.
  • Navigate to Configuration > Prevention Policies > External Device Control.
  • Under the Configuration tab, click + Add New Profile in the top-right corner.
  • Provide a suitable profile name and description.
  • Select the actions that you wish to restrict from the checklist provided.
  • Choose Allow or Block for the required peripheral devices.
  • Click Save.
Notes:
  • You can add devices to the blocklist by adding them within the Block listed Devices tab of the External Device Control page.
  • Devices configured under the blocklist will be restricted from use only if the Block all Blocklisted Devices action is chosen under the external device control policy.

Steps to add devices to the blocklist:

  • Select Endpoint DLP from the application drop-down at the top.
  • Navigate to Configuration > Prevention Policies > External Device Control.
  • Under the Block list Devices tab, click + Add USB devices.
  • Enter the Device Instance Path of the required device and click Add.
Notes: Steps to find the device instance path:
  • Navigate to the Start Menu and search for Device Manager.
  • Select Disk drives and right-click the required connected USB device.
  • Select Properties and, in the window that appears, go to the Details tab.
  • Select Device Instance Path from the Property drop-down.
  • The device instance path is now displayed.
