Project BIVOJ In 2023, NÚKIB continued developing the project BIVOJ in cooperation with partners. The project aims to establish a single, functional, secure shared platform providing security and communication services to public sector institutions, which would connect gradually to the system. Although the project is still in strategic development phase, some of its components are already being implemented. Under the coordination of the Deputy Prime Minister for Digitalisation and in close cooperation with NÚKIB, central government bodies are migrating to the uniform state domain gov.cz. This uniform domain will improve user-friendliness for citizens, provide legal certainty, and fortify resilience against DDoS attacks. Supply chain security The introduction of this mechanism should significantly reduce the impact of supply chain threats, such as supply disruptions caused by foreign states exerting their influence over suppliers, to key national ICT infrastructures. As mandated by the State Security Council in June 2022, NÚKIB is developing a supply chain security screening mechanism for state authorities to evaluate and mitigate risks associated with technology suppliers for strategically important infrastructure. The mechanism, under development as part of the new Act on Cybersecurity, includes mandates for NÚKIB and other relevant national authorities to screen suppliers and restrict the procurement of ICT supplies from suppliers deemed as high-risk. The proposed process for the screening and mitigation of threats applies to critical security supplies only and includes provisions for infrastructure managers to comment on proposed supplier restrictions and exemptions for suppliers of non-substitutable technologies to avoid undesirable impacts. The draft mechanism was finalised in 2023, and following inter-departmental consultation, merged with the Act on Cybersecurity to advance to the next legislative stages. Quantum threat mitigation Quantum computer development is proceeding rapidly and sparking great interest among professionals and the public alike. As the capabilities of quantum computers grow, they pose an increasing threat to current cryptographic standards. In response, NÚKIB has issued supporting documents (overview, minimum requirements for cryptographic algorithms, annex to the minimum requirements) explaining the nature of this threat and describing steps to mitigate the risks faced by cryptographic protection and cybersecurity in the coming years. 40
