In particular, the arrangement shall designate the person who will be responsible for meeting the information obligations and before which authority the data subjects may exercise their rights. 2. The terms of the arrangement referred to in the previous paragraph shall not prevent the data subject from exercising his or her rights against each of the joint controllers. Article 62 Security of processing (Articles 19 and 29 of the Directive) 1. The controller and processor, taking into account the state of the art, the costs of implementation and the nature, scope, context and purposes of the processing as well as the likelihood and severity of the risks involved by the processing for the data subjects, shall take the necessary technical and organisational measures to ensure a level of security appropriate to the risk during the processing of personal data, in particular as regards the processing of special categories of personal data. 2. The measures referred to in the previous paragraph may include, inter alia, the pseudonymisation and encryption of personal data, where such measures are possible for the purposes of the processing. The measures in accordance with paragraph 1 should ensure: (a) the confidentiality, integrity, availability and resilience of processing systems and services; and (b) the ability to restore the availability and access to personal data in a timely manner in the event of a physical or technical incident. 3. In respect of automated processing, the controller and processor, following an evaluation of the risks, shall implement measures designed to: (a) deny unauthorised persons access to processing equipment used for processing (‘equipment access control’); (b) prevent the unauthorised reading, copying, modification or removal of data media (‘data media control’); (c) prevent the unauthorised input of personal data and the unauthorised inspection, modification or deletion of stored personal data (‘storage control’); (d) prevent the use of automated processing systems by unauthorised persons using data communication equipment (‘user control’); (e) ensure that persons authorised to use an automated processing system have access only to the personal data covered by their access authorisation (‘data access control’); (f) ensure that it is possible to verify and establish the bodies to which personal data have been or may be transmitted or made available using data communication equipment (‘communication control’); (g) ensure that it is subsequently possible to verify and establish which personal data have been input into automated processing systems, and when and by whom the personal data were input (‘input control’); (h) prevent the unauthorised reading, copying, modification or deletion of personal data during transfers A’ 137/29.08.2019 of personal data or during transportation of data media (‘transport control’); (i) ensure that installed systems may, in the case of interruption, be restored (‘recovery’); (j) ensure that the functions of the system perform, that the appearance of faults in the functions is reported (‘reliability’) and that stored personal data cannot be corrupted by means of a malfunctioning of the system (‘integrity’); (k) ensure that the personal data to be processed on behalf of the controller can only be processed according to the instructions of the controller (‘processing control’); (l) ensure that the personal data are protected from loss and destruction (availability control); (m) ensure that the personal data collected for different purposes can be processed using organisational or spatial separation (possibility of separation). The purpose of the first subparagraph in indents (b) to (e) may be achieved, in particular, by means of encryption technology. Article 63 Notification of a personal data breach to the Authority (Article 30 of the Directive) 1. In the case of a personal data breach, the controller shall notify without delay and, where feasible, not later than seventy two (72) hours after having become aware of it, the personal data breach to the Authority, unless he or she reasonably considers on the basis of justifiable reasons that the breach is not likely to compromise the protected legal interests of a natural person. The notification of the breach to the Authority after the expiry of seventy two (72) hours shall be specifically justified as regards the reasons for the delay. 2.

Where it is not possible to provide the information referred to in the previous paragraph at the same time with the notification of the breach, the controller may provide the information in phases once it is available without further delay. 5. The controller shall document any personal data breach comprising of the facts relating to the personal data breach, its effects and the remedial action taken. 6. Where the personal data breach involves personal
