1. Hardware Encryption
Encrypting data is one of the basic features of a secure USB drive. There are two different types of encryption methods, software, and hardware; the main difference between the two is the location of the decipher key. While the software encryption method stores the decipher key on the PC, leaving it vulnerable to virus and hacking, the hardware encryption method keeps the decipher key on the USB drive to reduce the risk of it being exposed. If you are handling confidential or exposure-sensitive files, you should think about purchasing a hardware encrypted secure USB drive.
2. Automatic Self-Destruction Against Brute Force Attack
One of the simplest ways to hack into the secured information is by entering every possible combination until a match on the password is found. This is called the “brute force attack”. In order to prevent illegal access methods, the USB drive needs have a function where the data is completely deleted after a set amount of incorrect password attempts. Make sure your secure USB drive has safeguards against brute force attack.
3. Embedded with Vaccine Program for USB Drive
There are many factors that increase the chances of virus infection; the most influential factor is on how often the USB drive gets connected to an unreliable computer (i.e. public places, schools, libraries, and airports). Once infected, the USB drive acts as a host to infect other PCs. This is extremely dangerous, especially when the infected USB drive is connected to PCs that are connected to lab equipment or contains confidential data. The most efficient way to defend the USB drive from virus infection is to embed a vaccine program
on the USB drive. Anti-virus for USB drive is absolutely necessary when it comes to protecting your private data and files.
4. Need for Copy Protection
The basic function of a secure USB drive is to encrypt data, thus, preventing data leakage when lost or
stolen. However, sometimes those with access to the files would copy the shared files using a USB drive or external hard drive. In this case, the data stored on the USB drive could be saved to the local PC without any trouble.
To prevent data leakage through a friend, coworker or family member, copy protection is ideal. Although the copy protection function is optional, it is necessary to keep those who might be closer to you, out of your private life.
5. Do I need administrative USB drive?
Usually, secure USB drives are purchased by the company and given out to the employees. In which case, each USB drive is independently protected against copy protection, and the individuals become responsible for any leakage accidents.
The administrative USB drive is suitable for companies with a security administrator; the administrator controls every USB drive in the entire company with his own configured security policy. With the administrative USB drive, the security administrator can control password, copy protection, log collection, prevent data leakage, restore password, validity period and number of uses.
6. Reusable with Initialization Tool
What happens when you forget your password to access the USB drive? Some secure USB drives are not allowed to be initialized, meaning you have to buy a new one. Others are reusable right after initialization but the data will be lost.
Make sure to purchase a replacement secure USB drive or buy one that can be initialized.
