Analysing the Effects of Cyber Security on National Security from a Realist Perspective: "Stuxnet" Example

In this study, the effects of providing cyber security on national security are examined from a realistic perspective using the example of the Stuxnet virus. It has been stated that the increasing complexity of cyber threats due to technological advances poses serious risks to states' national security. In the study, the critical role of cyber security in protecting national security is emphasized through the Stuxnet attack. The Stuxnet attack is a cyber-attack on the facilities where Iran carried out its nuclear enrichment program in 2010. As a result of this attack, it was revealed that Iran had both interruptions in its nuclear program and a weakness in cyber security. As such, it is underlined that cyber security can affect the international balance of power and the strategic interests of states. From a realist perspective, since ensuring national security requires a resilient defense against cyber threats and vulnerabilities, it has become necessary to consider cyber security as an important parameter in determining national security policies. This study reveals the interdependent relationship between cyber security and national security in this age when cyberspace has become a very important arena for power struggles. Considering these reasons, it has been recommended that states, which realists consider the main actor in the international system, should make investments that will support their cyber security to protect their national security.
