In the rapidly evolving digital age, the confluence of cybersecurity threats and the assertion of digital sovereignty by states has created a complex, multi-dimensional challenge for international law. The existing legal regimes governing state behavior in cyberspace are fragmented, outdated, and ill-equipped to address the novel, intangible, and interconnected nature of the digital domain. This article examines the gaps and limitations in the current international legal frameworks and proposes a dynamic, adaptable approach to establishing a normative foundation for cybersecurity and digital sovereignty. The article highlights the urgent need for clear definitions and categories of cybercrimes and cyberwarfare under international law, as well as the development of appropriate legal responses and enforcement mechanisms. It also explores the tensions between state sovereignty and global Internet governance, proposing a balanced framework that upholds both the legitimate security interests of states and the fundamental principles of human rights, transparency, and multistakeholder collaboration. Central to the article's argument is the call for a flexible, evolutionary architecture of international cybersecurity law, capable of keeping pace with rapid technological advancements and the ever-changing threat landscape. This framework should incorporate mechanisms for continuous improvement, effective attribution and accountability, and the active engagement of international organizations and multistakeholder initiatives. The article further emphasizes the critical role of geopolitical challenges in shaping the development of international cybersecurity norms. It advocates for a nuanced, pragmatic approach that acknowledges the competing interests and values of different state actors while striving to find common ground and build trust through dialogue and cooperation. In an era of increasing digital interconnectedness and the erosion of traditional borders, this article presents a compelling case for the adaptation of international law to address the complex realities of the digital age. It offers valuable insights and recommendations for policymakers, legal experts, and scholars seeking to navigate the uncharted territories of cybersecurity and digital sovereignty in the 21st century.
