Secure your data — with passwords, encryption and backups

Data security

We live in a digital age

Humanity generates more data every day. Digital data will have grown to 175 Zettabytes by 2025. That's one hundred and fifty-nine billion one hundred and sixty-one million five hundred and seventy-two thousand eight hundred and ten Terabytes. Every connected person engages with digital data about 4.900 times per day. That's once every 18 seconds. You are no exception. A significant amount of your life is digitised and stored all over the place. Your phone, computer, watch and cloud services might know more about you than your closest friends.

Strong and unique passwords

Protect your data

In this chapter, we'll discuss how to prevent unauthorised access to your data. Use strong and unique passwords. Avoid re-using passwords for several devices or accounts. Use a password manager. And consider two-factor authentication for additional security.

We'll also discuss how an effective backup strategy can shield you from data loss, theft, deletion, corruption, leaks, ransomware, or worse.

VeraCrypt and Cryptomator

Encrypt your data

Finally, we'll discuss how to use encryption to make your data unreadable in case of a breach. For example if an attacker manages to hack your cloud storage account or gets unauthorised access to your computer.
