Database Encryption on Cloud

Introduction

When discussing data security in the cloud, it's important to understand the different layers of encryption. In Easy Cloud, your data is already protected with strong security measures. However, we are sometimes asked about an additional layer—encryption of data at rest. This article explains what that means, and why it may not be necessary or useful in the Easy Cloud environment.

Understanding Cloud Database Encryption

General Security Measures

In Easy Cloud, all database content is protected in the following ways:

The database is secured with a strong password
Server access is restricted to verified personnel only
Access is granted through secret SSH keys, not passwords

These measures already provide high-level protection from unauthorized access and external attacks.

What is Encryption of Data at Rest?

Encryption of data at rest means the data is encrypted when stored on disk, even if the server is powered off. This can help protect against physical theft of the storage device.

It is especially useful for mobile devices or laptops, where theft is a realistic concern.

Does It Improve Security in the Cloud?

Not really. In a cloud environment like Easy Cloud:

The servers are located in high-security data centers
Facilities have 24/7 surveillance, armed guards, and controlled access
The risk of physical disk theft is extremely low

Also, a common misconception is that encryption of data at rest protects against hackers. This is not true, because:

When the server is running, the data is unencrypted in memory
Hackers would access the data just like a legitimate process during uptime
Real protection comes from strong authentication and restricted access

Performance Impact

There is also a downside—application speed.

Encrypting data at rest causes latency in all operations
The database becomes up to 10% slower
Easy8 is heavily database-dependent, so users may notice the lag

In short, the user experience may suffer for little or no added security value.

Conclusion

Encryption of data at rest is technically possible in Easy Cloud (especially on private cloud setups), but it is not recommended. The added value is very limited in a secure hosting environment, and the performance impact outweighs the benefits.
