What does "data encryption" mean in the context of DSAC Annex B?

Data encryption refers to the method of transforming information into a format that is not easily readable by unauthorized individuals. This is crucial in safeguarding sensitive data, ensuring that even if it is intercepted or accessed without permission, it remains unintelligible to the unauthorized user.

In the context of DSAC Annex B, which focuses on security and data protection measures, encryption plays a vital role in maintaining confidentiality and integrity of data. It helps organizations comply with legal and regulatory requirements regarding data protection and privacy, as well as building trust with clients and stakeholders about the security of their information.

The other alternatives, while related to data management and security in various ways, do not capture the specific meaning of data encryption as the process of securing data to prevent unauthorized access. Data backup, compression, and data retention strategies are different aspects of data management that do not involve the transformation of data into a secure format.
