DATA-3 File System Encryption

What is this control about?

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

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