Tallinn Manual

The Tallinn Manual is a scholarly guide that clarifies how international law applies to cyber warfare and cyber operations conducted during conflicts. It offers principles and rules for states on how to responsibly conduct cyber activities, such as defending against cyber attacks or engaging in cyber defense, while adhering to existing laws like sovereignty and the prohibition of unjustified harm. While not legally binding, it serves as an important reference for policymakers, military planners, and legal experts to understand and navigate the complex legal landscape of cyberspace during conflicts.
