The development of cyber-policy and -infrastructure presents a unique challenge due to the “short arm” of predictive knowledge. This refers to the difficulty of predicting the impact of technological advancements and their associated risks in the future. Therefore, a precautionary approach should be taken to mitigate the risks and uncertainties associated with technology development. Policymakers should prioritize transparency and accountability in developing cyber-policy and -infrastructure. This can be achieved by involving stakeholders from various sectors, including industry, academia, civil society, and government agencies. By involving stakeholders, policymakers can ensure that a diverse range informs their decisions of perspectives and that the development of cyber-policy and -infrastructure is in line with the interests of society as a whole. Policymakers should embrace a flexible approach to policy development that can adapt to changing technological advancements. Cybersecurity threats and vulnerabilities constantly evolve, and policies must be flexible enough to adapt to these changes. This approach can be facilitated by creating mechanisms for continuous review and evaluation of policies to ensure their effectiveness in the face of new and emerging threats. Policymakers should prioritize education and awareness-raising campaigns for the public, policymakers, and industry professionals. This can include training programs for cybersecurity professionals and disseminating best practices for individuals and organizations to protect themselves from cyber threats. International cooperation and collaboration are essential in developing cyber-policy and -infrastructure. Cybersecurity is a global issue, and international cooperation can facilitate the sharing of best practices and promote greater harmonization of cybersecurity policies across different countries. Developing cyber-policy and -infrastructure requires a precautionary approach, flexibility, transparency, education, and international cooperation. Policymakers must recognize the short arm of predictive knowledge and take proactive steps to mitigate the risks and uncertainties associated with technology development.
