What this domain covers

What to know about Data Governance And Security

Be able to select the right control for a scenario: external key management for column encryption, a Data Processing Agreement for GDPR processing, and risk-ranked findings. The most important thing is matching the control to the specific threat and data type.

SQL Server column-level encryption using Always Encrypted with keys held in an external key store

GDPR controller-processor obligations established through a Data Processing Agreement

Database security review findings ranked by risk, such as excessive privileges or missing encryption

Technologies that limit data exfiltration by privileged administrators, including auditing and least privilege

Watch out for

Common Data Governance And Security exam traps

  • ▸Assuming Transparent Data Encryption protects individual columns; it encrypts data at rest but does not isolate sensitive PII fields.
  • ▸Confusing a Data Processing Agreement with a privacy notice or consent form when establishing the GDPR legal basis between controller and processor.
  • ▸Treating any misconfiguration as equally risky instead of ranking findings by exposure, privilege level, and sensitivity of affected data.
