After years of painstaking multilateral negotiations, the United Nations is stepping into a new chapter of international cybersecurity governance. In March 2026, the UN General Assembly will convene the organizational session of a permanent “Global Mechanism” dedicated to responsible state behavior in cyberspace — a landmark shift from the temporary, process-driven forums that have defined this space for the past decade.
From the OEWG to Something Permanent
The new body follows in the footsteps of the Open-Ended Working Group (OEWG), which ran from 2021 to 2025 and brought together all UN member states to debate norms, rules, and principles for responsible conduct online. The OEWG was itself a successor to earlier Groups of Governmental Experts (GGEs), which produced landmark reports on applying international law to cyberspace in 2013 and 2015.
What’s different this time is permanence. Rather than launching yet another time-limited working group and facing the familiar question of “what comes next?”, the General Assembly is establishing a standing mechanism — one designed to carry the conversation forward indefinitely. This matters. Cyber threats evolve faster than most multilateral processes can keep pace with, and a permanent institutional home sends a signal that states are serious about treating cyberspace as a domain requiring ongoing, collective stewardship.
The Hard Questions Haven’t Gone Away
The Global Mechanism inherits an ambitious — and unfinished — agenda. Central to its work will be the application of international law to cyber operations, a subject that has proven genuinely difficult to resolve among states with very different strategic interests and legal traditions.
Key debates include how the principle of sovereignty applies when a state’s digital infrastructure is targeted or compromised; whether states have a due diligence obligation to prevent malicious cyber operations launched from their territory by non-state actors; and how international humanitarian law (IHL) governs offensive cyber operations during armed conflict — questions that touch on proportionality, distinction between civilian and military targets, and the definition of “attack” in the digital realm.
These are not academic disputes. As cyber operations increasingly feature in geopolitical competition and armed conflict, getting the legal framework right has direct consequences for how states behave — and how they hold each other accountable.
States remain genuinely divided on many of these points. Some insist existing international law applies fully and directly; others argue that the unique characteristics of cyberspace require new treaty law or bespoke norms. Bridging that gap will be one of the mechanism’s defining challenges.
Early Signs of Progress
Despite the disagreements, negotiators have already chalked up a meaningful practical achievement: the launch of a global cyber Points of Contact (PoC) directory. This directory allows states to identify and communicate directly with designated national authorities in the event of a cyber incident — exactly the kind of confidence-building measure that can reduce misunderstanding and the risk of escalation.
It’s a modest step, but an instructive one. When legal and normative debates stall, practical infrastructure for communication and coordination can still move forward — and often does more to build trust than any declaration of principle.
The PoC directory reflects a broader lesson from the OEWG years: progress in multilateral cyber diplomacy tends to happen in layers. High-level political agreements on norms coexist with technical working-level cooperation, and the most durable gains often come from concrete, operational tools that states can use immediately.
What to Watch in 2026
The March organizational session will set the structural foundations of the new mechanism — its agenda, working methods, and the role of non-governmental stakeholders like civil society, the private sector, and academia. How inclusive the mechanism proves to be will say a great deal about whether it can generate legitimacy beyond governments.
Beyond process, substance will follow. Expect early debates to revisit the contested legal questions around sovereignty and IHL, and new discussions may emerge around artificial intelligence in cyber operations, ransomware as a tool of state and non-state actors, and the protection of critical infrastructure — healthcare, energy, and financial systems — from cyber attack.
The Global Mechanism won’t resolve all of these challenges quickly. Multilateral diplomacy rarely does. But its establishment reflects a recognition that cyberspace cannot be governed through ad hoc processes alone. A permanent forum, imperfect as it may be, is a necessary foundation for the long work ahead.
The organizational session of the UN Global Mechanism on cybersecurity is scheduled for March 2026. Further details on its mandate and structure are expected to emerge in the weeks leading up to that session.
