Written by Margaret Siu and Tommy Hall. In an era where digital technology permeates every aspect of our lives, national security strategies increasingly hinge on robust cybersecurity measures. This is particularly evident in the approaches of Taiwan and Japan, two democratic governments at the forefront of integrating advanced technological defences against emerging digital threats. The evolving cybersecurity strategies of Taiwan and Japan are not merely reactive measures to emerging threats but are emblematic of broader global trends where digital security is inextricably linked to political stability. Their experiences offer vital insights for other governments grappling with similar challenges, emphasising the importance of agility, technological innovation, and international cooperation in crafting national security strategies for an interconnected digital world.
