Encrypt data and devices
- Michael Laurentius
Purpose
Encryption encodes information in such a way that unauthorized parties should be unable to read it. This helps to prevent compromises to the confidentiality and integrity of your data and is a part of robust, multi-layered security approach. Whether it is a compromised desktop, or a lost mobile or storage devices, encryption ensures that your data remains accessible to only you and your team.

Initial considerations
Not all encryption algorithms are the same. AES-128 bit (or equivalent) is the absolute minimum you should consider. AES-256 bit or greater is preferred.
Determine your data's classification.
Classifying your data is the first step to knowing what safeguards are required to securely store your data.
Level 3 and level 4 data must be stored on a secure server or must be encrypted at rest on a laptop, mobile device, or removeable storage.
Consult with your local IT group.
Your department or division may support or recommend specific encryption solutions.
What can I do?
Enable or install full-disk encryption packages.
