Thanks to its regulatory powers, robust digital economy, and active foreign and security policy, the European Union is one of the key players in cyberspace. The EU strongly promotes the position that international law, and in particular the United Nations (UN) Charter, applies in cyberspace. As a complement to binding international law, the EU endorses the voluntary non-binding norms, rules and principles of responsible State behaviour that have been articulated by the UN Group of Governmental Experts. It also encourages the development and implementation of regional confidence building measures, both in the Organisation for Security and Co-operation in Europe and other regions. On a bilateral level, the EU has established cyber dialogues with strategic partners to reinforce the exchange of good practices, lessons learnt and further the idea of responsible state behaviour in cyberspace.

Costa Rica has established itself as a leading country in technological adoption, in combination with a complete commitment to sustainability and the protection of the environment. Information and communications technology services accounted for 49% of the country’s exports (twice the average of OECD countries), placing the Central American country at the forefront of the digital economy.

Brazil is the world’s eighth largest economy in terms of GDP, and by far South America’s most populous and powerful state. While the country has suffered economic and political crises since 2014, it has made significant advances in domestic digitization and played a pivotal, albeit ambiguous role in international negotiations on cyberspace. Brazil has the world’s fifth largest internet user base, after China, India, the United States and Indonesia, and is a leading country in South America when it comes to ICTs usage. The share of Brazilians using the internet has increased from less than 3% of the population in 2000 to more than 68% in 2019. As such, Brazil remains a critical partner for the EU’s efforts to build a secure, stable and rights-based cyberspace.

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.

Costa Rica has played a paramount role in the Organisation of American States as is one of seven American countries that sponsored a resolution within the framework of the OAS as part of a Working Group on Cooperation and Confidence-Building Measures in Cyberspace. The resolution is inspired by the work of the United Nations Group of Governmental Experts and aims at enhancing interstate cooperation, transparency, predictability, and stability in cyberspace.

In accordance with the output produced by the 2013, 2015, and 2021 consensual reports of the United Nations Groups of Governmental Experts on Developments in the Field of Information and Telecommunications in the Context of International Security (UNGGE), Brazil believes that international law enjoys general applicability in cyberspace. For Brazil, this also includes international humanitarian law and international human rights law. Nevertheless, Brazilian delegations have expressed concern that unqualified transfers of international humanitarian law and an unlimited right of self-defence could legitimise cyberspace as a military domain, while also challenging the protective value of sovereignty and cementing a Western-biased status quo.

Since 2014, the EU’s ambition has been to act as an ‘honest broker’ on multilateral discussions surrounding issues of cyber governance and norms of responsible state behaviour, aiming to ensure the support and partnership of proactive players in the context of the global debate. The EU has long promoted the need for voluntary, non-binding norms. It believes that norms crystallised under the UN GGE process should generally not be revisited and that progress should be made on matters relating to their implementation. 
Within the OEWG, the EU advanced a suggestion to develop a global repository of existing practice within the United Nations, which would enable UN member states to showcase how they are implementing the voluntary norms of responsible state behaviour, confidence building and other measures.

Costa Rica has a long history of collaborating on cyber issues within the OAS Cyber Security Program, from training to capacity-building for both the public and private sectors. At a 2019 intervention, Costa Rica recognised the leadership carried out by the aforementioned Working Group in coordinating the response to cyber incidents regionally and establishing a cooperative framework of action to cyber threats.
Costa Rican participation in the UN OEWG is guaranteed until 2025. As part of the second substantive session in 2022, Costa Rica confirmed - along with several other countries - that international law is fully applicable to the use of ICT by states [OH1], with a focus on how international humanitarian law and the principles of humanity, necessity, proportionality, and distinction apply in cyberspace.
An interesting approach was taken by Costa Rica during this session, as the Caribbean country emphasised a multi-stakeholder approach to cybersecurity, involving the private sector, civil society, and researchers’ analysis, information, and capacity on threat.

Brazilian diplomats portray Brazil’s role in the often polarised debates on norms of responsible state behaviour as that of a broker or strategic bridge-builder between the different camps rather than a mere ‘swing state’ and highlight that balancing between both camps serves to maintain an independent foreign policy. Brazil sought to focus its chairmanship of UN GGE’s third and fourth iterations on three issues: the role of civilians in cyber conflict, the right to respond, and attribution. Since the 2013 Snowden revelations, the country has been a stark champion of data protection, showcasing exceptional norm entrepreneurship
in relation to cyber-surveillance norms. Brazil has also expressed support for the proposal of adopting a legally binding instrument in the medium to long-term to prevent the militarisation of cyberspace.

The EU places great importance on cyber resilience and capacity building. Internally, the Union has built a robust legal acquis in relation to the resilience of critical infrastructures, the cornerstone of which rests upon the 2016 Network and Information Security (NIS) Directive and the 2013 and 2019 Cybersecurity Acts. This legal meshwork seeks to integrate cybersecurity into all elements of the supply chain and introduce soft law mechanisms like the EU cybersecurity certification scheme. In doing so, it harmonises national cybersecurity capabilities, cross-border collaboration and the supervision of critical sectors across the EU. 
In the coming months, the Commission intends to add upon the existing cyber-acquis by introducing an array of new initiatives, such as the updated NIS Directive (the so-called NIS2), a proposal on a Critical Entities Resilience (CER) Directive, and a plan to launch a network of Security Operations Centres across the Union. The aim is to create a Union-wide ‘cybersecurity shield’ that will facilitate the detection of cyberattacks and provide an impetus for proactive action. 
This internal buildup of capabilities is supplemented by the development of a specialised ‘cyber diplomacy toolbox’ that allows the Union and its Member States to address cyber incidents through various joint policies, from cooperation and stabilisation measures to restrictive measures and attribution.

In 2016, Costa Rican Cybersecurity Incident Response Team (CSIRT) joined CAMP, an international alliance that serves as a platform for the members to enhance their cybersecurity capacity.
Costa Rica is also collaborating with Israel on cyber issues and digital transformation in an effort that has the potential to streamline innovation in the public sector, transforming public services and institutions and positioning Costa Rica as a regional benchmark in cybersecurity.
On a national scale, Costa Rica launched a digital transformation strategy for the public sector in 2018 and is now working to create a strategy for the implementation of Artificial Intelligence. The initiative seeks to promote the use of digital technologies and access to scientific knowledge, innovation, technology, and telecommunications for social and productive transformation.
Having suffered a cyber attack in 2022, Costa Rica is now positioning cybersecurity as a top national priority, and the Ministry of Science, Innovation, Technology and Telecommunications is beginning to implement various actions to detect, respond and correct cyber intrusions, build faster and more robust response protocols, and train individuals in skilled threat detection.

Brazil’s 2020 National Cybersecurity Strategy (E-Ciber) outlines ten strategic actions to be undertaken in relation to cyber resilience, which include the extension of international cooperation and the enhancement of protection for critical infrastructure. The Strategy pledges Brazil to encourage international cooperation in cybersecurity, participate in joint cyber resilience events and exercises, and expand cybersecurity cooperation agreements. On the level of discourse, Brazil remains committed to international cyber cooperation in resilience, staying true to its traditional stance in favour of multilateral solutions.

The EU has been an early champion of the Budapest Convention signed under the auspices of the Council of Europe, given the overlapping membership of the two organisations. Much of the EU’s cyber diplomatic efforts have focused on promoting the Convention as the main instrument of choice for fighting cybercrime on a global level. EU member states have consistently opposed Russian bids for replacing this regime with another legal framework. 
The Union is represented in the recently constituted Ad Hoc Committee established by UNGA resolution 74/247 by its Member States and is currently focused on ensuring that the process is inclusive, transparent, consistent with the progress of the UNGGE and OEWG processes, and committed to legal consistency.

Costa Rica is one of the few Latin American countries to have signed the Budapest Convention on Cybercrime, along with the First and Second Protocol (this one was signed in 2022 but yet to be ratified), and is at the forefront of cybercrime legislation in the region.
National legislation on cybercrime is fully compliant with the Convention and is contained in the Law on Intervention of Telecommunications and the Law of Computer Crimes and Related Crimes. It includes penalties for committing cybercrimes in the country. Additionally, legislative regulations were introduced to govern the use of social networks and other electronic means.
Their Cybersecurity Policy from 2017 was updated in 2021 with the creation of the CSIRT, the implementation of cybersecurity protocols across public institutions and the establishment of partnerships with strategic actors, mainly in the private sector.

Brazil originally refrained from signing the Budapest Convention on Cybercrime and had expressed scepticism in response to invitations to accede. The argument advanced was that the treaty is Western-biased and lacking in inclusivity, given that Brazil was not part of the original drafting process. During voting for UNGA Resolution A/74/401, the Russian-sponsored proposal for a new binding Cybercrime Convention, Brazil abstained; during meetings with the BRICS leaders, however, Brazil had endorsed Russian pleas for a new cybercrime instrument to replace the Budapest regime. Upon invitation by the Council of Europe, Brazil finally initiated the process of accession to the Convention in December 2019 and is now an observer country.
