The Baltic States can support 5G security through transatlantic cooperation by sharing their experiences and best practices with other countries. The authors suggest that the Baltics have a unique perspective on 5G security due to their location and history of cyber attacks. They also highlight the importance of collaboration between the private and public sectors in ensuring the security of 5G networks. The authors recommend that the Baltic States work with the United States and other allies to develop standards and best practices for 5G security, and to share their expertise with other countries. Additionally, they suggest that the Baltic States should invest in research and development to improve the security of their 5G networks and to develop new technologies to address emerging threats. Overall, the authors believe that transatlantic cooperation can play a key role in ensuring the security of 5G networks and promoting a more secure future for the region.
