How should data be classified according to DSAC Annex B guidelines?

The classification of data according to DSAC Annex B guidelines is focused on the sensitivity and importance of the information. This approach ensures that data is appropriately protected based on its potential impact if disclosed, altered, or destroyed. By emphasizing the sensitivity and importance of the information, organizations can develop targeted security measures, access controls, and handling procedures that align with the risk associated with specific data types.

This is crucial for safeguarding sensitive information, such as personally identifiable information (PII), financial records, and classified materials, which require higher levels of protection compared to less sensitive data. The emphasis on information sensitivity aligns with broader best practices in data governance and risk management, helping organizations to prioritize security efforts and allocate resources effectively according to the risks posed by different data classifications.

Other approaches, such as classifying data based on physical location, cost of storage, or solely on user-generated classifications, do not adequately address the foundational principles necessary for effective data security and risk management.
