The US
believes that international law is applicable in cyberspace. As part of the ‘like-minded’ coalition, the US recognises a need to acknowledge the full breadth of relevant international law, including international humanitarian law (IHL), human rights law, customary international law on the responsibilities of states for internationally wrongful acts. The general applicability of IHL in cyberspace is not to be misconstrued as a tacit endorsement of aggression in the cyber domain; instead, it only serves to remind states of the responsibility to respect and protect civilians in the event of armed conflict.
In the context of multilateral fora, US diplomats have specifically
emphasised the applicability of the right to self-defence under Art. 51 of the UN Charter, noting that a State may lawfully take cyber-based or non-cyber-based countermeasures in response to internationally wrongful cyber activities attributable to another State, but only subject to the requirements of the doctrine under international law and the principles of necessity and proportionality.
As a member state of the UNGA, Uruguay
expressed their views at the OEWG in 2021, considering cybersecurity an essential element in the prevention of international conflicts. Uruguay provides a rather humanitarian approach to international law and its application on cyber issues. The country is a
member of international organisations that promote the development and compliance with standards of transparency and access to information, such as the Open Government Partnership, the Electronic Government Network of Latin America and the Caribbean (GEALC) and Digital Nations.
Uruguay was the first Latin American country, in 2013, to sign the only existing binding, international document concerning the Automatic Processing of Personal Data (known as
Convention 108). Its signature and membership have been
ratified in 2021.
Uruguay’s Digital initiatives at the national level are also in compliance with the Digital Agenda for Latin America and the Caribbean (
eLAC by CEPAL). In particular, Uruguay’s
Cybersecurity goal is in line with
CEPAL’s framework for confidence-building measures such as combating digital crime by formulating public policies and strategies for cybersecurity and critical infrastructure protection.
Under the auspices of the UN, the EU and its Member States have
consistently reaffirmed that a universal cyber security framework can only be grounded in existing international law, including the Charter of the United Nations in its entirety, international humanitarian law, and international human rights law.
Addressing issues as to how existing international law and international humanitarian law, including the principles of humanity, necessity, proportionality and distinction, apply to the use ICTs by States is necessary to increase accountability and transparency. International humanitarian law is fully applicable in cyberspace and this should not be misunderstood as legitimising the use of force between states in the cyber domain. The EU has typically opposed calls for the need to adapt existing international law as a means to develop a new legal instrument for cyber issues.
