Data encryption in cloud in Cybersecurity - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is data encryption in the cloud?

Data encryption in the cloud means converting your data into a secret code so that only authorized people can read it, even if someone else accesses it.

beginner

Why is encryption important for cloud data?

Encryption protects your data from hackers and unauthorized access by making it unreadable without the right key, keeping your information safe in the cloud.

What are the two main types of encryption used in cloud storage?

The two main types are: 1) Encryption at rest, which protects stored data, and 2) Encryption in transit, which protects data while it moves between your device and the cloud.

What is a key in data encryption?

A key is a secret code used to lock (encrypt) and unlock (decrypt) data. Only people with the right key can read the encrypted data.

How does cloud service provider encryption differ from client-side encryption?

Cloud service provider encryption means the cloud company encrypts your data, while client-side encryption means you encrypt data before sending it to the cloud, giving you more control over security.

What does encryption do to your data in the cloud?

A Converts it into a secret code

B Deletes it permanently

C Copies it to another server

D Makes it visible to everyone

Encryption changes data into a secret code so only authorized users can read it.

Which type of encryption protects data while it is being sent to the cloud?

A Encryption at rest

B Data backup

C File compression

D Encryption in transit

Encryption in transit protects data as it moves between your device and the cloud.

Who controls the encryption keys in client-side encryption?

A Cloud service provider

B The client (user)

C Internet service provider

D No one controls keys

In client-side encryption, the user controls the keys, increasing security.

What happens if someone without the key tries to read encrypted data?

A They see a secret code or gibberish

B They can read it easily

C They delete the data

D They get access to the key

Without the key, encrypted data looks like unreadable code.

Which is NOT a benefit of encrypting data in the cloud?

A Protects data from hackers

B Makes data unreadable without a key

C Automatically deletes data after use

D Helps meet privacy regulations

Encryption does not delete data; it protects it by making it unreadable without the key.

Explain in your own words why data encryption is important when using cloud services.

Think about what happens if someone tries to see your data without permission.

Describe the difference between encryption at rest and encryption in transit.

Consider when and where the data is protected.
