As the use of technology increases overtime, the use of the internet and cyber space is also rapidly increasing. Cyber space is now a part of our daily routine. From banking, entertainment, transport even our social lives are dependent on the internet. This over use of the internet comes with a price and that may come in the form of virus, worms, hacking and identity theft. The open use of cyber space has not just connected the entire world with speed and ease but has also left the world open to hackers and other individual out for their selfish motives. This paper will try to define what cyber warfare and what are its impacts on modern society.Koblentz and Mazanec have defined cyber warfare as ‘the use of computer networks to disrupt, deny, degrade, or destroy information resident in enemy computers and computer networks, or the computers and networks themselves’ (Gregory D. Koblentz & Brian M. Mazanec 2013). As technology becomes more and more advanced so does the ability to conduct war. Criminals from around the globe have targeted both government and private networks to start information and cyber warfare which also entail attacks that are backed by political and military forces from around the globe.The world began to see the dangers caused by modern weapons in World War I when chemical weapons were introduced. After that in World War II, nations developed nuclear weapons which led to the destruction of 2 entire cities. Today, in the war on terror, the US has unmanned drones which can be used to strike terrorists without endangering the lives of our soldiers. The ability to conduct warfare via advanced technological methods has contributed to an increase in information security awareness and the need for one to protect an entities infrastructure. Subsequently, with the advent of cyber warfare there has been and increased risk of threats and vulnerabilities to systems that hold or transmit data.The threat of a cyber-attack on our nation’s infrastructure is now viewed by the majority of American’s as an imminent and credible one that demands greater resources and spending. A recent survey shows that 92% of all Americans agree that cyber warfare is a dangerous threat to the public utilities, transportation and government infrastructure. Cyber warfare is viewed as an imminent threat in light of increased news coverage of recent attacks. 60% of Americans are also in favor of increased government spending in defense of such attacks. However, there is a divide amongst the people as to whether the corporations should be responsible for their own defense or if this is the governments’ responsibility (Americans Willing to Spend More to Thwart Cyber Attacks: Survey, 2013, p. 1). When it comes to cyber security, any attack which is conducted against the network of a government organization or even the private sector involves one to able to corrupt and control a computer network or any other type of target. For example unstructured level has the ability to conduct basic hacks against individual systems using tools created by someone else, while the advanced structured level means the attacker has the capability to perform more advanced attacks against multiple systems and can modify or create basic hacking tools. The final level is the most complex level as it is described as the hacker having the ability to coordinate attacks that cause mass disruption against defenses, and the ability to create sophisticated hacking tools.
