What is one obligation that the General Data Protection Regulation (GDPR) imposes on data processors?

The GDPR imposes several obligations on data processors, such as maintaining records of processing activities, cooperating with supervisory authorities, and notifying data controllers of personal data breaches. One of these obligations is to implement appropriate technical and organizational measures that ensure an appropriate level of security for the personal data processed on behalf of the data controller. This is stated in Article 28(1) and Article 32 of the GDPR1. The other options are not obligations of data processors under the GDPR, but rather of data controllers or joint responsibilities of both parties. References: GDPR
