Autonomous Cyber Capabilities under International Law

The application of international law to cyber operations and to the use of autonomous military technology continues to be the subject of intensive debate. Nevertheless, the legal implications of autonomous cyber capabilities have thus far received little attention. A research paper on autonomous cyber capabilities under international law by the researchers of the NATO CCDCOE Maarja Naagel and Ann Väljataga in cooperation with Dr Rain Liivoja from the University of Queensland focuses on the international law aspects of autonomous cyber capabilities.

There are still debatable legal issues in relation to regular cyber capabilities and wholly unresolved sets of issues in relation to autonomous weapon systems.  The ambition of this paper is not to come up with definitive answers or draw a comprehensive list of related legal and policy issues. Instead, the paper first provides a general technological background to explain how the autonomous technological systems work and also gives examples of autonomous functionality in defensive and offensive cyber capabilities. Next, the paper makes a few overarching observations about the relationship between autonomy and the law, and then describes possible breaches of sovereignty that may result from the use of autonomous functionality in cyber capabilities. The paper then looks at autonomous cyber capabilities in the context of ius ad bellum and ius in bello respectively, and in the end, explores the responsibility under international law for uses of autonomous cyber capabilities.
