Flash drives inherently grant users both unrestricted read and write privilege but such access rights may not be practical for vertical market applications.

For instance, https://www.everythingusb.com/nexcopy-lock-license.html systems are mostly offline or air-gapped for security reasons. Updating firmware and patches for these critical infrastructures, therefore, relies on the use of direct-attached storage (e.g. flash drives). Off-the-shelf drives will not suffice as they don’t guarantee data security against sabotage. In such cases, companies would want a peace-of-mind solution to meet their security requirements of dispatching read-only drives.

Honeywell recently released a cybersecurity report claiming that 37% of threats were specifically designed to utilize removable media, which almost doubled from 19% in 2020. This number could be drastically reduced when the proper media and solution are used.

For example, there are various non-permanent methods to secure flash drives, including changing read-only attributes with DISKPART through command utility as well as manually setting drive security rights from Windows. These methods get the job done for the average user – although not a significant hurdle for the more determined wanting to take advantage and wreak havoc.

Said another way, these steps will not stop a user with unsupervised access from reverting the drive write permission back to the original state and doing whatever they want with the data. A hardware solution is regarded as a more foolproof solution because hacking into the machine code of a chip is more difficult than hacking into software code. Nexcopy has a hardware solution called Lock License and it addresses the needs of medical and industrial control system cybersecurity concerns.

The overview is Nexcopy’s Lock License working similar to a write-once-read-many (WORM) solution. The solution provides device integrity by having a default state of read-only mode. Yet Nexcopy gives the user the ability to temporarily remove the write protection in a controlled manner. For Lock License, the core component is the custom-coded chip firmware that provides configurable security options.
