Advanced Permissions for Storage Devices

Advanced permissions apply when you grant limited permissions to most storage devices. The permission can be any of the following:

  • Modify

  • Read and execute

  • Read

  • List device content only

You can keep the permissions limited but grant advanced permissions to certain programs on the storage devices and on the local endpoint.

To define programs, configure the following program lists.

Table 1. Program Lists

Program List

Description

Valid Inputs

Programs with read and write access to devices

This list contains local programs and programs on storage devices that have read and write access to the devices.

An example of a local program is Microsoft Word (winword.exe), which is usually found in C:\Program Files\Microsoft Office\Office. If the permission for USB storage devices is "List device content only" but "C:\Program Files\Microsoft Office\Office\winword.exe" is included in this list:

  • A user will have read and write access to any file on the USB storage device that is accessed from Microsoft Word.

  • A user can save, move, or copy a Microsoft Word file to the USB storage device.

Program path and name

For details, see Specifying a Program Path and Name.

Programs on devices that are allowed to execute

This list contains programs on storage devices that users or the system can execute.

For example, if you want to allow users to install software from a CD, add the installation program path and name, such as "E:\Installer\Setup.exe", to this list.

Program path and name or Digital Signature Provider

For details, see Specifying a Program Path and Name or Specifying a Digital Signature Provider.

There are instances when you need to add a program to both lists. Consider the data lock feature in a USB storage device, which, if enabled, prompts users for a valid user name and password before the device can be unlocked. The data lock feature uses a program on the device called "Password.exe", which must be allowed to execute so that users can unlock the device successfully. "Password.exe" must also have read and write access to the device so that users can change the user name or password.
