L 194/6 EN Official Journal of the European Union 19.7.2016 (32) Competent authorities or the computer security incident response teams (‘CSIRTs’) should receive notifications of incidents. The single points of contact should not receive directly any notifications of incidents unless they also act as a competent authority or a CSIRT. A competent authority or a CSIRT should however be able to task the single point of contact with forwarding incident notifications to the single points of contact of other affected Member States. (33) To ensure the effective provision of information to the Member States and to the Commission, a summary report should be submitted by the single point of contact to the Cooperation Group, and should be anonymised in order to preserve the confidentiality of the notifications and the identity of operators of essential services and digital service providers, as information on the identity of the notifying entities is not required for the exchange of best practice in the Cooperation Group. The summary report should include information on the number of notifications received, as well as an indication of the nature of the notified incidents, such as the types of security breaches, their seriousness or their duration. (34) Member States should be adequately equipped, in terms of both technical and organisational capabilities, to prevent, detect, respond to and mitigate network and information system incidents and risks. Member States should therefore ensure that they have well-functioning CSIRTs, also known as computer emergency response teams (‘CERTs’), complying with essential requirements to guarantee effective and compatible capabilities to deal with incidents and risks and ensure efficient cooperation at Union level. In order for all types of operators of essential services and digital service providers to benefit from such capabilities and cooperation, Member States should ensure that all types are covered by a designated CSIRT. Given the importance of international cooperation on cybersecurity, CSIRTs should be able to participate in international cooperation networks in addition to the CSIRTs network established by this Directive. (35) As most network and information systems are privately operated, cooperation between the public and private sectors is essential. Operators of essential services and digital service providers should be encouraged to pursue their own informal cooperation mechanisms to ensure the security of network and information systems. The Cooperation Group should be able to invite relevant stakeholders to the discussions where appropriate. To encourage effectively the sharing of information and of best practice, it is essential to ensure that operators of essential services and digital service providers who participate in such exchanges are not disadvantaged as a result of their cooperation. (36) ENISA should assist the Member States and the Commission by providing expertise and advice and by facilitating the exchange of best practice. In particular, in the application of this Directive, the Commission should, and Member States should be able to, consult ENISA. To build capacity and knowledge among Member States, the Cooperation Group should also serve as an instrument for the exchange of best practice, discussion of capabilities and preparedness of the Member States and, on a voluntary basis, to assist its members in evaluating national strategies on the security of network and information systems, building capacity and evaluating exercises relating to the security of network and information systems. (37) Where appropriate, Member States should be able to use or adapt existing organisational structures or strategies when applying this Directive. (38) The respective tasks of the Cooperation Group and of ENISA are interdependent and complementary. In general, ENISA should assist the Cooperation Group in the execution of its tasks, in line with the objective of ENISA set out in Regulation (EU) No 526/2013 of the European Parliament and the Council (1), namely to assist the Union institutions, bodies, offices and agencies and the Member States in implementing the policies necessary to meet the legal and regulatory requirements of network and information system security under existing and future legal acts of the Union. In particular, ENISA should provide assistance in those areas that correspond to its own tasks, as set out in Regulation (EU) No 526/2013, namely analysing network and information system security strategies, supporting the organisation and running of Union exercises relating to the security of network and information systems, and exchanging information and best practice on awareness-raising and training. ENISA should also be involved in the development of guidelines for sector-specific criteria for determining the significance of the impact of an incident.
