Securing Data at Rest with IBM Guardium Data Encryption

This topic describes how to secure data on persistent storage (data at rest) in SingleStore with IBM Guardium Data Encryption. This configuration allows you to protect all SingleStore information, including data files, backups, and logs from unauthorized access, including by unauthorized administrative users. The process is also known as Transparent Database Encryption or TDE.

IBM Guardium Data Encryption encrypts all protected SingleStore data with strong encryption. If the encrypted data is obtained in any way by someone without keys to access it, it will be useless. Even the root user on the Linux system running SingleStore can be prevented from accessing the information directly via the files where it is stored, even if they impersonate a user with access by using sudo. Keys can also be revoked to render data inaccessible.
