DATA-3 File System Encryption

What is DATA-3 File System Encryption Control?

File system encryption protects individual files or file systems by encrypting them with a specific key and making them accessible only to authorized persons.

There are no mandatory encryption mechanisms to use; this is left to the discretion of each company. Therefore, as an organization, you can edit the TrustCloud control ‘File systems for databases and other sensitive data storage require at least block-level encryption’ to match your unique encryption mechanisms.

What evidence do auditors look for?

Most auditors, at a minimum, are looking for the below-suggested action:

1. Provide a screenshot of the file storage configuration settings showing that encryption is enabled.

Evidence example

For the suggested action, an example is provided below:

1. Provide a screenshot of the file storage configuration settings showing that encryption is enabled.
   The following screenshot shows an encryption configuration that has encryption enabled.
   NOTE: This example illustrates the configuration evidence that an auditor will expect. This is not necessarily shown as block-level encryption. There is no mandatory level of encryption. Just provide a screenshot of your encryption configuration.
