COOPERATION BETWEEN THE NÚKIB AND OTHER SUPERVISION BODIES ON CONTROLS IN 2020 exercises help strengthen relations between the participants as well as with the partners cooperating with the NÚKIB on their preparation. Last year, the NÚKIB continued in its cooperation in control activities with other regulatory bodies, with the aim of minimising the burden on the obliged entities. For example, the NÚKIB established cooperation with the State Office for Nuclear Safety via a memorandum, whereby these institutions confirmed mutual support and cooperation beyond the scope of control activities. cyber coalition ���� international cyber security exercise CYBER SECURITY EXERCISES: GREAT INTEREST, LIMITED OPPORTUNITIES As in previous years, in 2020 the NÚKIB noticed an in­ creased demand for exercises by Czech organisations and entities. This demand could not be completely met, however, because of the measures associated with the global COVID-19 pandemic. The total number of organ­ ised exercises, which are a proven tool for increasing the cyber security level, was negatively affected by the impossibility of meeting in person to discuss questions posed by a realistic scenario customized for the specif­ ic audience. Such restrictions on meetings were both on the side of the NÚKIB and the requesting subjects, which on the one hand emphasised the safety of their employ­ees for logical reasons, and on the other prior­ itized other critical activities of their own. Despite the above, the NÚKIB organised or coordinated eight national and international exercises in 2020. Apart from the representatives of the NÚKIB, about 100 participants from various organisations activ­ely participated in the exercises in the Czech Republic. The exercise as part of the General Staff Course and the exercise for the Prague Castle Administration are par­ ticularly worth highlighting. THE ADDED VALUE OF THE CYBER SECURITY EXERCISES Exercises are an invaluable source of new knowledge, experience, and technical skills. They give the NÚKIB an opportunity to identify weaknesses in cyber security, point them out and provide an excellent tool for the verification and revision of strategies and procedures. As a tool for identification, definition and confirmation of trends, they also provide inputs for the preparation of other awareness-raising and educational activities. Furthermore, the This annual international exercise held by NATO, with the NÚKIB coordinating the civilian part and the Cyber and Information Warfare Command the military part at national level, saw a dramatic change compared to previous years because of the COVID-19 pandemic. The participation of the coordinating organisations and their partners was significantly limited, and the planning process and the actual exercises took place virtually. Despite the necessary adjustments to the current sit­ uation, NÚKIB representatives also managed to actively participate in the Core Planning Team responsible for the preparation and organisation of the exercises at the highest level, for the third consecutive year. Thereby, the Czech Republic again contributed to one of the largest international cyber security exercises to the maximum extent.
