Chapter 5 analyses the increasing digitalization of Sweden's Society's critical infrastructure and its connection to the internet. The increased efficiency brings with it enlarged risks and vulnerability to cyber-attacks and information operations. Vulnerabilities include both civil society and military capabilities, which are directly affected by the threat of cyber warfare and indirectly threatened through a possible collapse of civilian functions on which the armed forces depend. Sweden stands on the threshold of a new digitized society, and requires a digital immune system that reduces the vulnerability of society, through increased risk awareness among government agencies, industry, and politicians and better preparedness to counter threats by planning, exercises and possibly an early warning system.
