Why Hardware-Encrypted USB Drives Are the Best Option for Regulatory Compliance in 2022

Many governments and industries worldwide have mandated that various forms of personal data be protected by encryption while at rest or in transit. A few examples of commonly known regulations are HIPAA in health care, GDPR in the European Union, the California Consumer Privacy Act (CCPA), and Payment Card Industry Data Security Standard (PCI DSS). Non-compliance to a single regulation can lead to heavy-duty fines and loss of corporate reputation, loss of business, and legal implications.

Many individuals in charge of companies' IT departments or security issues deal with strained budgets. As a result, they are moving to software encryption, which can offer the exact same encryption capabilities – such as AES-256 XTS – as do more expensive hardware-encrypted USB drives, for compliance purposes, unaware of the dark side of software encryption: it is not compliant with regulations.

The issue is that users can easily remove the software-encryption feature from their USB drives. The primary reason they do so is for access to the files without use of a password, or they forgot the password but needed to use the drive. In the 15 seconds, it takes to do that, all stored encrypted files are removed, and the drive is ready for users to copy new files to the drive for easy – albeit unencrypted – access. Hence, software encryption is considered removable encryption.

How do hardware-encrypted USB drives meet an organization's needs for regulatory compliance? Read on.

1. Hardware encrypted USB drives have encryption that is always ON

Unlike software encryption, which does not prevent repeated password guessing through software dictionary attacks, hardware-encryption limits password retries to 10 times or fewer – and wipes out the data when the wrong passwords are entered ten times in a row. This is very secure in the age of supercomputers.

2. Hardware-encrypted drives use premium encryption controllers and incorporate many security features

While manufacturers, such as Kingston, don't always disclose all security countermeasures, there is a countermeasure to protect against BadUSB that we can discuss. At the factory, when the firmware is loaded on hardware-encrypted drives only, the firmware is digitally signed and loaded. This means that when these encrypted USBs are plugged in, the encryption controller first checks the integrity of the firmware through the digital signature and only loads it if it passes. Any attempt to replace the firmware will brick the drive, becoming non-functional.

3. Hardware encrypted USB drives can have custom Product IDs (PIDs) set up for a specific company

These premium drives can have a digital identifier programmed into them so that if a drive is plugged into the company's inner or outer firewall, the drive can be identified as a company-issued drive. For example, if an employee loses the company drive and buys the same model at retail, the newly purchased drive will not validate on the company network. This customization adds another layer of security to the use of USB drives.

Hardware-Based Encryption...

• Uses a dedicated processor, physically located on the encrypted drive
• Processor contains a random number generators to generate an encryption key, which is unlocked by the user's password
• Offers increased performance by off-loading encryption from the host system
• Includes safeguard keys and critical security parameters within crypto-hardware
• Authentication takes place on the hardware
• It does not require any type of driver installation or software installation on the host PC
• Protects against the most common attacks, such as cold-boot attacks, malicious code, brute force attacks
