data

Why is data important?
there are many information in it.
Why should we protect it?
An unsecured system is at threat of hackers altering, deleting, or corrupting your data.
What could happen to data if we don’t take precautions to protect it?
Hackers will encrypt it, making it incomprehensible to anyone who does not hold the ‘key’ to decode it.
