Disk Encryption

Disk encryption is a technology which protects information by converting it into unreadable code that cannot be deciphered easily by unauthorized people. Disk encryption uses disk encryption software or hardware to encrypt every bit of data that goes on a disk or disk volume.

Full disk encryption protects all data on a system, including the operating system. But it only protects the system while it’s turned off. It also doesn’t protect systems from being attacked by hackers over the internet. It only protects against someone who gains physical access to your device.

Use disk encryption when storing confidential or sensitive data.

Disk encryption can mitigate risks of data exposure from loss or theft of stored data (i.e., data at rest).  Full disk encryption can provide “blanket” protection so the user does not have to protect individually stored files and ensures that any remnants of data are secure.  Such remnants can be temporary files, browser cache files, and application-specific automatic backups.  All current operating systems provide disk encryption capability.

Encryption is especially warranted for portable storage devices such as USB keys or external hard drives, which are extremely vulnerable to loss. 

You can also use certain encryption softwares like VeraCrypt, TrueCrypt, BitLocker, etc.

It’s always better to keep every single piece of data and information on your devices encrypted and secure.

Though this will only help you protect your data from physical attacks, you’ll still have one less thing to worry about.

Although if you believe you don’t have any such incriminating or important information on your devices, then you don’t really need to. But I’d suggest that you should try to stay as secure as possible.

Disk Encryption is just one way to protect yourself from data theft attacks.

We’ll discuss the other ways in future.

Let me know if there is anything in particular you’d like me to write about concerning data security.
