Write blocking, a subset of write protection, is a technique used in computer forensics in order to maintain the integrity of data storage devices. By preventing all write operations to the device, e.g. a hard drive, it can be ensured that the device remains unaltered by data recovery methods.
Additional software can be installed on an external USB drive to prevent access to files in case the drive becomes lost or stolen. Installing software on company computers may help track and minimize risk by recording the interactions between any USB drive and the computer and storing them in a centralized database.
Finally the call device.controlTransferOut() will set up the device to communicate through the WebUSB Serial API. Once the set up is all done, data can be transferred to the device using device.transferIn() to transfer bulk data to the device, similarly its sister function device.transferOut() to read data from the device.

USB OTG defines two roles for devices: OTG A-device and OTG B-device, specifying which side supplies power to the link, and which initially is the host. The OTG A-device is a power supplier, and an OTG B-device is a power consumer. In the default link configuration, the A-device acts as a USB host with the B-device acting as a USB peripheral ...
Consequently, the device enforcing the access-control list must separately resolve names to numeric addresses. This presents an additional attack surface for an attacker who is seeking to compromise security of the system which the access-control list is protecting. Both individual servers and routers can have network ACLs.
Some software developers use traditional USB flash drives as software license dongles that contain hardware serial numbers in conjunction with the stored device ID strings, which are generally not easily changed by an end-user. A developer can also use the dongle to store user settings or even a complete "portable" version of the application.
Permissions are a means of controlling and regulating access to specific system- and device-level functions by software. Typically, types of permissions cover functions that may have privacy implications, such as the ability to access a device's hardware features (including the camera and microphone), and personal data (such as storage devices, contacts lists, and the user's present ...
It is available as free software under the GNU General Public License and currently runs under both Linux and OS X. [4] The program, when installed, prompts the user to create a whitelist of devices that are allowed to connect to the computer via its USB ports, which it checks at an adjustable sample rate.
