Find out everything you need to know about data in transit encryption and encrypting data at rest. From emails to IaaS, encryption ensures your data stays safe.
The difference between data at rest and data in transit
When data collects in one place, it is known as data at rest. This data is stable and inactive, and therefore cannot travel across a network or within the system. When at rest, data can be stored on hard drives, backup tapes, in offsite cloud backup and on mobile devices. As it is not moving through any networks, it is not being operated by any application. Data at rest should always be encrypted and where possible additional layers of security should be put in place, such as multi-factor authentication, cloud antivirus and both digital and physical access controls.
Data in transit is the opposite of data at rest. Data in transit is active and can be transferred via cables and wireless transmission to other locations either within or between computer systems. This data can travel across a network and is capable of being read, updated or processed. Examples include data in motion from local to cloud storage or an email being sent – when data arrives in the recipient’s inbox, it becomes data at rest.
How encryption keeps data safe?
Encryption is a powerful and effective technique for data security. It encodes the data into an indecipherable format to enable authorized access only. Using an algorithm to encrypt data and then a key for the receiving party to decrypt, the security measure creates ciphertext – referring ..
