¹Member States should contribute to the establishment of the EU Cybersecurity Crisis Response Framework as set out in Commission Recommendation (EU) 2017/1584¹⁵ through the existing cooperation networks, in particular the European cyber crisis liaison organisation network (EU-CyCLONe), the CSIRTs network and the Cooperation Group. ²EU-CyCLONe and the CSIRTs network should cooperate on the basis of procedural arrangements that specify the details of that cooperation and avoid any duplication of tasks. ³EU-CyCLONe’s rules of procedure should further specify the arrangements through which that network should function, including the network’s roles, means of cooperation, interactions with other relevant actors and templates for information sharing, as well as means of communication. ⁴For crisis management at Union level, relevant parties should rely on the EU Integrated Political Crisis Response arrangements under Council Implementing Decision (EU) 2018/1993¹⁶ (IPCR arrangements). ⁵The Commission should use the ARGUS high-level cross-sectoral crisis coordination process for that purpose. ⁶If the crisis entails an important external or Common Security and Defence Policy dimension, the European External Action Service Crisis Response Mechanism should be activated.
