Understanding data security
Data security is one of the greatest concerns for enterprises today, especially with the ever-increasing amount and value of collected data. It is all about protecting digital data from the actions of unauthorized users (such as data leaks or breaches) or from destructive forces. As part of that, there are a few concepts that you need to become familiar with, including encryption, backup and restore, data masking, and data erasure. Let's get to know each of them.
Data encryption
Data encryption can be applied at multiple levels and stages of the data life cycle. This includes when the data is stored at its final data store (encryption at rest) and while data is in motion, moving from one system to the other (encryption in transit).
Encryption in transit is typically achieved by encrypting the message before it is transmitted and decrypted at the destination. This process intends to protect data while being transferred against attackers who...
