# Advanced Device Control

While working with data storage devices such as CD/DVDs and USB-based devices such as pen drives, organizations are concerned with the following:

- Autorun feature does not activate any infection.
- Unnecessary data or applications do not clog the systems.

This feature allows the administrators to create policies with varying rights. For example, administrators can block complete access to removable devices, give read-only and no write access so that nothing can be written on the external devices. They can also customize access to admin configured devices. Once the policy is applied to a group, the access rights are also applied. You can use the exception list to exclude the devices from the device control policy.

- Some devices (e.g. Nokia phones, BlackBerry phones) may need system reboot or device reattachment for device access rights to be applied.
- On blocking SATA Controller from Advanced Device Control, you may frequently see SATA Controller blocked prompts even when actual blocking is not performed.
- While any ongoing session of Webcam or Bluetooth is in progress, changing access right to block will not interrupt this current ongoing session. The device may need reattachment or system reboot for access rights to be applied.
- After blocking devices such as USB storage, CD/DVD drives, and card readers, they will remain visible in Explorer. However, any attempt to access them will be restricted by the system.
