However, we must bear in mind that there are very few devices that incorporate security measures (such as file encryption) that allow protecting confidential information stored in them.
The devices that incorporate it use standard encryption protocols to encrypt files or folders, through the use of a password or even through the use of biometric identification (fingerprint).
These devices are not well known and have a higher price than the rest so their use is very reduced.
How then can we protect confidential information about a pendrive or disk that does not incorporate this feature?
The solution is to encrypt each of the files classified as confidential before storing them on the device using programs based on either symmetric cryptography or private/public key.
For this we can follow two approaches: encryption of individual files and encryption of the entire device.
