The easiest way to secure your USB thumb drive is to use hardware based encryption, these secure USB flash drive will cipher every single bit of data stored in them and are trouble free to use for users, there is no learning curve.
However, just because you are using encryption it does not mean you are safe, you will need to make sure that nobody can crack it, choose an USB thumb drive with no backdoor encrypted with a well known attack resistant algorithm like AES (Advanced Encryption Standard) and if you are going to use it in a business environment choose a FIPS (Federal Information Processing Standard) certified thumbdrive.
Benefits of hardware based encryption
- Hardware encryption is faster than software as you are not using computer resources
- Hardware encryption is shielded from malicious code targeting encryption software
- Hardware encryption does not normally require you to install drivers or administration rights
- A malicious hacker will need physical access to the device to crack it
- Hardware based encryption requires very little training to use it
Disadvantages of hardware based encryption
- Your encrypted USB flash drive can be stolen or misplaced and you will lose all the data
- Hardware based encryption might not have been scrutinized as much as open source encryption
- Hardware based encryption does not allow for scalability, i.e. increasing encrypted container size
