33) Does your organisation regularly test backups to ensure their effectiveness?

IT Operations
Backup Encryption

Answer yes if your organisation regularly tests its backup data to ensure that the backups are effective and can be used when required. State the frequency of the tests in the notes section.

Backups are copies of your production data, which means that they need to be at least as secure as your main production site. Backups should be encrypted to prevent unauthorised access and to protect their confidentiality. If a malicious actor can get hold of your backups, that is as good as breaking into your systems.

Many tools used to take backups of systems include a feature that encrypts the backups for you. If your IT team take backups manually, they can also implement encryption tools to protect them.

Encryption algorithms vary in strength, and many older algorithms that used to be secure have now been broken. It is important to ensure you utilise a strong encryption algorithm such as AES (Advanced Encryption Standard), with a suitable long encryption key (e.g. AES-256).

How to implement the control

You must ensure that backups are encrypted to protect them from unauthorised access. The encryption algorithm used should be a recognised standard, for example, AES-256.
