Digitalization has made our societies vulnerable to cyber threats – from electric grids to elections. This is also true for militaries, and cyber defence has become a natural task for all defence organizations. Cyber threats cannot be considered as new threats anymore. However, the cyber threat landscape is changing rapidly, and will continue to do so. Malicious viruses, hackers, hacking, etc., are still part of this landscape, but cyber weapons and cyberattacks originating from nation states are the primary security concerns today.
