Answer:
Here’s how encryption can help keep your data safe from prying eyes – even if your device is stolen or your cloud account is hacked
Disk encryption
Most computers still have removable hard disks that aren’t soldered onto the motherboard; alternatively, as extra storage, people use external disks. That’s why having full-disk encryption is a great extra security layer: if you misplace your disk or it is stolen, then no one can access any of the information on it. The disk is fully encrypted, including all your data, your software and the operating system you’re running. Unless you can enter the key at boot-up, your whole computer essentially becomes quite an expensive paperweight. There are several commercial options with advanced features, open source projects and built-in options in most major operating systems.
When it comes to smartphones and tablets, the equivalent functionality to look for is device encryption, which is built into, and commonly enabled by default, on contemporary devices. There are many easily found online guides that explain checking for and, if necessary, enabling device encryption for Android or iOS devices.
Cloud encryption
Most of us use cloud storage for its ease of access – you can do it from anywhere at any time so long as you have an internet connection. Unfortunately, that accessibility introduces its own set of challenges. Over the years, cloud storage services have experienced security breaches, either due to human error or targeted attack by ne’er-do-wells. Therefore, encrypting your files before uploading them to the cloud should be a no-brainer.
