Abstract
This paper answer to what degree a potential threat from cyberspace are affecting Western democracies security, and the thesis concludes that there is a medium threat against state security or stability, but the threat is primarily directed towards the physical domain, and only have limited effect in relation to the psychological domain. The paper uses John A. Warden’s theoretical systems-of-systems model to treat the state as a system and thereby identify potential vulnerabilities in Western democracies. The analysis shows that there is great deference to the degree to which each system can be affected by carrying out the attack in cyberspace. The analysis shows that the areas or subsystems of energy and the financial sector are the systems which will have the greatest impact within the criteria integrity and availability. The conclusion also shows that it can be extremely difficult to predict the secondary, third and even fourth -order effects if i.e. the power grid completely or partially is affected, but the conclusion calls for governmental action within a reasonable timeframe, because state security is to some degree actually threatened.
