I think the days of thinking that cybersecurity primarily refers to the ability to protect machine data are long gone in the past. What Beskow and Carley bring up is social cybersecurity which is pretty much humans using technology to hack other humans. How society can be changed and affected by the use of social media and other types of technologies that are able to reach a mass audience in a short period of time. According to Beskow and Carley (2019), “This twist on the traditional cyber paradigm is sometimes referred to as “cognitive hacking.” While leveraging the cyber medium for mass delivery, this emerging information warfare leverages advances in targeted (or micro) marketing, psychology and persuasion, policy gaps at and between private and government institutions, and understanding of the social sciences to deploy coordinated information operations with strategic effect”. I personally think that social cyber security can be as dangerous or more dangerous than some cyber hacks. First of all we have seen historically how propaganda has changed the way we fight wars. In the Vietnam War, with the successful publication of peace posters and the antiwar movement. It is already hard fighting a war in another country but to also face major backlash and a social movement to withdraw from the war gave a small country like Vietnam a technical victory over the mighty USA. So if other countries are able to slowly convince the people to turn their backs on the government or to cause confusion then that may lead to a surprising upset in the future of war and geopolitical warfare.
