Defending Digital Sovereignty

You are advising a democratic government that wants to reduce foreign digital interference without undermining free expression or open internet principles. Map the main threat categories, the policy tools available, the trade-offs of each, and the institutional design needed for long-term resilience. Include examples of preventive measures, detection systems, public communication strategies, and oversight safeguards. Then propose a practical roadmap for building trust before, during, and after high-stakes public events.
