In the age of the digital world, cyber threats and vulnerabilities have gained the attention of security leaders as well as countries across the globe. The issue of cyber warfare is no longer limited to organizations. Rather, even state-sponsored cyber-attacks are being organized and launched against enemy states. Reuters news agency in the UK reported that the Carnegie Endowment for International Peace discovered that cyber-attacks on financial institutions are increasingly being linked to nation-states and the damages were disruptive and destructive, rather than just theft. The majority of nation-state attackers belonged to North Korea, China, Iran, and Russia.
