Password protect USB Drive

Password protection of a USB flash drive is a good way of data protection simply because this is the only extremely hard form of protection to break. In so doing, data can never fall into unauthorized hands. There are a variety of selections to make if or when one chooses this method of data protection and that best suits their needs. This method allows for the protection of a single document or folder and ensures that the encryption of the whole flash drive is not the only solution to data protection. One shouldn’t go through the entire-disk encryption process.

Method 1: individual data password protection on a USB drive

In an instance when one has extremely sensitive data that wants to ensure no average person could access it, there is no need to encrypt the whole drive. There are built-in features that can be used (if present), to password protect the specific data or a third-party tool. Files and folders can in windows can be password protected by use of third-party tools. Folder lock, in this case, can be very assertive and comes as a portable (can run on any computer without installation) version and can be carried around in the USB drives. They will let you password-protect specific folders and files.

Method 2: partial encryption of the USB

There are instances when one has very sensitive data and therefore simple password protection is not enough per say. In that sense, a separate partition of the USB drive can be encrypted and all crucial data in it. In this way, one can always access all the unprotected data with no need for a password and access the important data by just keying in the password.

Antivirus protection

Apart from data falling into unauthorized hands, data can be affected by malware or even be corrupted to the extent that it loses its value or meaning. For this reason, there is a number of things or steps that can be taken to prevent data loss.

Step 1: backup

By backing up data in another drive or storage device ensures that in an instance when you lose your data from your USB drive, you can always have copied it back to the drive from the backup earlier created. This ensures there is recovery after a data loss.

Step 2: write-protection

If one uses their flash drives in computers that are infected by a virus, chances are that the virus could spread to their flash drives. This happens in a situation when one copies data from the virus infected computer into the flash drive. This copying of data is possible by the writing onto that drive. Therefore, one can disable the copying of additional data to a USB drive by the use of write-protection to ensure viruses are not replicated to the drive and the initial data affected. The read-only in this case, therefore, is used and thus data can only be read from the drive but not written to the same.
