2Encrypting Your Hard Drive/USB Sticks
Encrypting data becomes essential in today’s digital age as it considered the last line of defense if an attacker successfully gains access to your confidential data. In other words, encryption will be your last hope to prevent the compromise, use, or disclosure of your sensitive information to the public or to your enemies. Keeping stored information on a hard drive secure is easy when using encryption software. For instance, Windows provides a built-in encryption utility that is available for most of its versions (Windows 7 and beyond) called BitLocker. Using this utility is easy; all you need to do is to right-click the drive you want to encrypt and select Turn on BitLocker. A wizard will appear that walks you through all the steps to configure your drive encryption (setting a password and storing a recovery key).
