6.3 Device Control Policies

Device control policies regulate the use of various computer-related devices within an organization. They help standardize how computers access storage and communication devices, preventing confidential information from being leaked through external devices and enhancing enterprise security and management compliance.

Supported device types include Storage Devices, Communication Interface Devices, Dial-up Devices, USB Devices, Network Devices, and Other Devices.

Storage Devices:

Device Type Description
Floppy Drive Controls floppy drives. If disabled, floppy drive access is blocked.
CD/DVD Drive Controls CD-ROM and DVD drives.
CD/DVD Burner Controls the ability to burn discs.
Tape Drive Controls tape drives.
Removable Devices Controls storage devices other than internal hard drives (IDE, SCSI, SATA), including USB drives, external hard drives, memory sticks, smart cards, MO, and Zip drives.
Non-System Drives Applies to all drives except the system drive.
Portable Devices Includes devices such as smartphones.

CD/DVD burning control focuses on restricting disc-burning operations. Supported tools include:

Device Type Description
Dedicated Burning Tools AnySecura’s proprietary disc-burning software.
Other Burning Tools Any disc-burning software other than AnySecura’s proprietary tool.

Mobile smart devices primarily refer to smartphones. Policies can control how these devices connect to client machines. Supported access methods include:

Device Type Description
Portable Device Mode Device connects as a portable device.
USB Storage Mode Device connects as a USB mass storage device (some devices may call this "mass storage mode").
Via Phone Management Software Device connects using third-party phone assistant software.

Communication interface devices include:

Device Type Description
Serial Port COM port.
Parallel Port LPT port.
USB Controllers & Connectors Universal Serial Bus controllers and hubs.
SCSI Interface SCSI and RAID controllers; used by SCSI hard drives.
1394 Controller IEEE 1394 bus controller (1394 slot), functions similarly to USB.
Infrared Infrared devices.
PCMCIA Card PCMCIA slot, functions similarly to USB controllers.
Bluetooth Devices Bluetooth-enabled devices.
Modem Dial-up device.
Direct Cable Connection Direct connection between two computers via USB, COM, or parallel ports.

Bluetooth devices include:

Device Type Description
Bluetooth Mouse Manages usage of Bluetooth mice
Bluetooth Headset Manages usage of Bluetooth headsets
Bluetooth File Transfer Controls file transfers via Bluetooth devices

Dial-up connections include:

Device Type Description
Dial-up Connection Controls access to dial-up connections

USB devices include:

Device Type Description
USB Keyboard Controls usage of USB keyboards
USB Mouse Controls usage of USB mice
USB Modem Controls usage of USB modems
USB Imaging Device/Camera Controls USB cameras, scanners, and digital cameras
USB CD-ROM Controls USB CD-ROM drives
USB Storage Controls USB storage devices
USB Hard Drive Controls usage of USB hard drives
USB Network Adapter Controls usage of USB network adapters
Other USB Devices Controls USB devices not listed above

Network devices include:

Device Type Description
Wireless Network Adapter Controls usage of wireless network adapters
PnP Network Adapter (USB, PCMCIA) Hot-swappable network adapters
Virtual Network Adapter Non-physical adapters, either motherboard-independent or virtual

Other devices include:

Device Type Description
Audio Devices Sound, video, and game controllers
Virtual CD/DVD Drive Controls usage of virtual CD/DVD drives
Wireless Networks Controls access to specific wireless networks using device descriptions. Leaving the description blank applies to all networks.
  • Device description format: SSID=<network name>|BSSID=<network address>. You can specify only SSID, only BSSID, or both. Wildcards are supported, and multiple network descriptions are separated by semicolons.
  • Example:
  • SSID=teclink_11|BSSID=aa-77-dd-00-88; SSID=teclink_10; BSSID=aa-ee-dd-00-88
Any New Device Controls any newly connected device. If set to block, all new devices are disabled.

Policy Example 1

In some companies, listening to music or watching videos during work hours is prohibited. A device control policy can disable audio devices during this time.

Policy:Select the time range as "Working Hours," set the mode to "Block," and check "Audio Devices" in the device list. Computers with this policy applied will have their sound cards disabled.

Policy Example 2

To protect sensitive company documents, employees can be restricted from copying files via removable storage or CD/DVD burners.

Policy:Set the mode to "Block" and select the devices to restrict, such as removable drives, floppy disks, CDs, or burners. Computers with this policy applied will be unable to use these devices.

Policy Example 3

Some companies restrict employees to using only internal wireless networks for management purposes. Administrators can set a device control policy for target computers (e.g., the entire network) as follows:

  • Block all wireless networks: Set the mode to "Block," check "Wireless Networks" in the device list, and leave the device description blank.
  • Allow internal networks: Set the mode to "Allow," check "Wireless Networks" in the device list, and specify the company’s internal network information in the device description.

Example:

SSID=teclink_11|BSSID=aa-77-dd-00-88-ff; SSID=teclink_10; BSSID=aa-ee-dd-00-88-cc

After applying the policy, clients can only connect to the following networks:

  • Network named teclink_11 with AP address aa-77-dd-00-88-ff
  • Network named teclink_10
  • Network with AP address aa-ee-dd-00-88-cc
