DSB (Datenschutzbeauftragter) is the Data Protection Officer (DPO), the person who monitors compliance with the GDPR and other data protection regulations within an organization. Certain organizations are legally required to appoint a DPO (GDPR Art. 37).
The DPO advises management and departments, conducts data protection impact assessments, serves as a point of contact for data subjects and supervisory authorities, and oversees staff awareness. The DPO must be free of conflicts of interest — IT managers or executives are therefore unsuitable. In practice, the DPO and the Information Security Officer (ISO) work closely together, since data protection and information security overlap in many measures.
