Data protection doesn’t stop with data being produced. It also applies to saved, archived and erased data.
Data backups, by way of reversibility over time, remain independent of key changes made at regular intervals (corporate security rules), if dealing with encryption and/or tokenisation.
Secure archiving through strong protection within the storage layer, whilst allowing authorised users to unprotect the archived data with cleartext viewing within the framework of a defined processing purpose.
Erasure of data, in accordance with your rules, policies and the regulatory framework (e.g. data subjects’ right to be forgotten).
