Encrypting fields and attachments

Once cryptographic modules are created, a security admin can define the encrypted fields configuration (EFC) and opt to encrypt a field or attachment on a table.

How to encrypt fields

Note: Encrypted fields aren’t audited by design. This behavior isn’t configurable.

  1. Specify the key source: ServiceNow generated keys or your customer-supplied keys (bring your own key) in System Security > Field Encryption Settings.
  2. After specifying the key source, create a cryptographic module or use an existing cryptographic module. Start with Create a cryptographic module for instructions.

    Note: If you use customer-supplied keys, follow the directions in Create cryptographic module for Field Encryption and Configure properties for customer-supplied keys.

  3. Create an encrypted field configuration to define where the encryption is applied. Here, you specify the target table and choose whether to encrypt a column or attachments within the table. See Set encrypted field configurations to get started.

Note: See Field Encryption Enterprise examples that illustrates how to encrypt fields and attachments using customer-supplied keys.
