What is data masking and why is it important for compliance?

Data masking is the process of obscuring specific data within a database to protect sensitive information. It's crucial for compliance because it helps organizations meet regulations like GDPR and HIPAA by ensuring that personal data is not exposed during testing or development.

Can you give me examples of data masking techniques?

Sure! Common data masking techniques include substitution, shuffling, and encryption. For instance, substitution replaces sensitive data with fictional but realistic data, while shuffling rearranges data within a column.

How does data masking differ from data encryption?

Data masking alters the data to protect it, while encryption transforms data into a coded format that can only be read with a decryption key. Masking is often used for non-production environments, whereas encryption secures data in transit or at rest.

What are the risks of not implementing data masking?

Not implementing data masking can lead to data breaches, regulatory fines, and loss of customer trust. Sensitive information could be exposed during development or testing, putting the organization at risk.
