What is the difference between data at rest and data in transit?

Can you explain the difference between data at rest and data in transit?

Sure! Data at rest refers to inactive data stored physically in any digital form (like databases or storage devices). Data in transit, on the other hand, is data actively moving from one location to another, such as across the internet or through a private network.

Why is it important to differentiate between the two?

It's crucial for security reasons. Data at rest can be protected with encryption and access controls, while data in transit needs secure transmission protocols to prevent interception.

What are some common security measures for each type?

For data at rest, measures include encryption, access controls, and regular backups. For data in transit, using SSL/TLS protocols and VPNs are common practices.

Can you give examples of each?

Certainly! An example of data at rest is a database storing customer information. An example of data in transit is an email being sent over the internet.
