I made this diagram to give a high-level visual illustration of what actually happens in the background when a user attempts to view column-level encrypted (CLE) data in ServiceNow. There are many nuances to the feature, as well as a premium license with additional functionality (Column Level Encryption Enterprise/CLEE). Check out the docs here for deeper reading -> https://lnkd.in/g4cPiMJe
The purpose of this diagram is to see the base functionality of CLE at a high-level. The below does not include the additional CLEE features available
Field Types Supported :
🔐 Attachments
🔐Date
🔐Date/Time
🔐String
🔐URL
Quick crash course for those unfamiliar with some of the terms in the diagram:
KMF: Key Management Framework. Securely manages encryption keys, overseeing their distribution, storage, and lifecycle to ensure data is encrypted and decrypted appropriately by the encryption service.
RBAC: Role-Based Access Control.
Ciphertext: Encrypted form of data that has been transformed from its original, readable form (plaintext) using an encryption algorithm to secure it from unauthorized access.
Encryption Services: Referring to ServiceNow's services that manage the encryption and decryption processes, utilizing encryption algorithms and keys provided by the Key Management Framework to secure data as it is written to or retrieved from storage.
