Privacy Impact Assessment and Security Testing: Two Sides of Data Protection for Singapore Enterprises

Privacy Impact Assessments (PIAs) and security testing complement each other: PIAs identify what personal data is processed, how, and what risks exist; security testing verifies that the controls protecting that data actually work. Integrating both means: using PIA results to scope security testing (prioritising systems that process sensitive personal data), testing controls identified in the PIA (encryption, access control, anonymisation), and feeding security test results back into privacy risk assessments. This integrated approach satisfies both privacy regulators and security auditors.
