How To Secure Your USB Flash Drive
1. Keep it Properly
Never leave your USB flash drive unattended or connected to your computer. Doing so will make it easy for anyone who wants to obtain it. Keep it away from the eyes of people, but hide it at a place where you can easily remember.

2. Encrypt Files and the USB Flash Drive
Encryption is the process of securing data by encoding it in a manner that only allows it to be read by those with the correct key or password. You can decide to encrypt each document and file on the USB flash drive using document processing programs or encrypt the flash drive if it has an in-built encryption system.
Another way is to use third-party encryption software to encrypt the files and the flash drive. Third-party encryption software options include BitLocker, AxCrypt, TrueCrypt, and VeraCrypt.
With encryption software, your flash drive is useless to anyone who obtains it, as they won’t be able to access your data without the key or password.
3. Lock Files With A Secure Password
Unlike encryption, you cannot secure a USB flash drive with a single password. You can, however, manually secure each file with a unique password before saving it on the flash drive. This is easy to do as Microsoft Office applications have built-in strong password protection, a package that enables users to secure their data by adding a password to the file before saving.
Ensure that you use a strong and unique password that you create and know only to you. Do not use the same password for all files; instead, use passwords that you can easily remember. When forming a password, avoid using easily identifiable information, such as your name, phone number, birth date, or the information of any relative.

4. Use a Hardware-Encrypted USB Flash Drive
Apart from encryption software, hardware-encrypted flash drives are also available for use. Using such gives you a sense of security and assurance. Hardware-based encryption and password protection are security solution that safeguards your classified or personal data.
Without the PIN, no one can view the contents of the USB flash drive, even if they connect it to a computer. Most of the time, these flash drives come with Read-only access, which makes the data readable only by the owner.
Recent technology on these flash drives features an alphanumeric keypad, allowing you to easily input your PIN to access your data.
5. Do Not Connect Your USB Flash Drive to Unsecured Devices
One way to avoid a security breach is to avoid connecting your USB flash drive to unsecured or third-party devices.
The only computer you can be sure of its security is your own, so unless you’ve run a malware scan on the computer you want to connect to, do not do it.
To also ensure that your personal computer is secured, install up-to-date antivirus software on it and regularly update it.

6. Sync Important Data
Sync is the shortened form of the word ‘synchronize’. Syncing is the process of maintaining the same data in multiple locations simultaneously.
To secure the data on your USB flash drive, you can sync all important data with another device or software, such as Google Drive or Dropbox Smart Syncing. It helps prevent data loss, and in case the data is missing, you can access and delete it from the other device.
When important data is synced with other devices, you can access it from anywhere, eliminating the need to carry a flash drive.
