(a) A processor shall adhere to the instructions of a controller and shall assist the controller in meeting the controller’s obligations under sections 42-515 to 42-525, inclusive. Such assistance shall include: (1) Taking into account the nature of processing and the information available to the processor, by appropriate technical and organizational measures, insofar as is reasonably practicable, to fulfill the controller’s obligation to respond to consumer rights requests; (2) taking into account the nature of processing and the information available to the processor, by assisting the controller in meeting the controller’s obligations in relation to the security of processing the personal data and in relation to the notification of a breach of security, as defined in § 36a-701b, of the system of the processor, in order to meet the controller’s obligations; and (3) providing necessary information to enable the controller to conduct and document data protection assessments.

(b) A contract between a controller and a processor shall govern the processor’s data processing procedures with respect to processing performed on behalf of the controller. The contract shall be binding and clearly set forth instructions for processing data, the nature and purpose of processing, the type of data subject to processing, the duration of processing and the rights and obligations of both parties. The contract shall also require that the processor: (1) Ensure that each person processing personal data is subject to a duty of confidentiality with respect to the data; (2) at the controller’s direction, delete or return all personal data to the controller as requested at the end of the provision of services, unless retention of the personal data is required by law; (3) upon the reasonable request of the controller, make available to the controller all information in its possession necessary to demonstrate the processor’s compliance with the obligations in sections 42-515 to 42-525, inclusive; (4) after providing the controller an opportunity to object, engage any subcontractor pursuant to a written contract that requires the subcontractor to meet the obligations of the processor with respect to the personal data; and (5) allow, and cooperate with, reasonable assessments by the controller or the controller’s designated assessor, or the processor may arrange for a qualified and independent assessor to conduct an assessment of the processor’s policies and technical and organizational measures in support of the obligations under sections 42-515 to 42-525, inclusive, using an appropriate and accepted control standard or framework and assessment procedure for such assessments. The processor shall provide a report of such assessment to the controller upon request.

(c) Nothing in this section shall be construed to relieve a controller or processor from the liabilities imposed on the controller or processor by virtue of such controller’s or processor’s role in the processing relationship, as described in sections 42-515 to 42-525, inclusive.

(d) Determining whether a person is acting as a controller or processor with respect to a specific processing of data is a fact-based determination that depends upon the context in which personal data is to be processed. A person who is not limited in such person’s processing of personal data pursuant to a controller’s instructions, or who fails to adhere to such instructions, is a controller and not a processor with respect to a specific processing of data. A processor that continues to adhere to a controller’s instructions with respect to a specific processing of personal data remains a processor. If a processor begins, alone or jointly with others, determining the purposes and means of the processing of personal data, the processor is a controller with respect to such processing and may be subject to an enforcement action under § 42-525.
