A recent Data Governance Survey conducted by Redgate of over 500 SQL Server professionals showed that 61% of respondents were using production data for non-production workflows; a process that is often seen as necessary for the reliability of development, testing, and other similar workflows. However, with data privacy legislation such as the GDPR, POPI, and HIPAA, we can often be prevented from utilizing this data unless we are able to anonymize/pseudonymize or mask it first.
When masking these sets of data, we are often required to mask a variety of data-types from names to credit card numbers and, unsurprisingly, email addresses. Ultimately, data copied into pre-production workflows should never compromise the security of data subjects stored in production; the most obvious blunder to avoid being never accidentally sending an email to all your contacts that exist in Test.
