The International Telecommunication Union ( Itu ) Defines Cyber Security

Cyber security threats change quickly as Internet increases, and also the related dangers are getting to be progressively international. Being covered against cyber security threats requires almost all end users, actually the most complex versions, to know the particular threats in addition to enhance their particular safety measures with a continuing foundation. On April 28, 2014 President Obama has declared that the “cyber threat is one of the most serious economic and national security challenges we face as a nation” and that “America 's economic prosperity in the 21st century will depend on cyber security.” The internet enables and also helps people in a many ways and a example is collect, store, process huge amounts of data, which includes vulnerable data of small business, transactional and personal. Everything in this world is based on internet now a days.

Cyber security consists of technologies, processes and measures that are designed to protect systems, networks and data from cyber crimes.

Cyber security, also referred to as information technology security, focuses on protecting computers, networks, software programs and data from unintended or unauthorized access, change or destruction. Post 9/11 and other terrorist attacks, the United States grows its endeavors to repulse cyberattacks, U.S. corporate organizations and the government agencies wind up in strife over how to adjust to new methods of security and privacy. The current state of security measure protocols and privacy policies placed by the US government in cyberspace raises concerns for the 99%. This is due to the recent cyber-attacks on American corporate organization systems and government alike, where their digital information and network infrastructures within the systems were compromised, and personal data was hacked and stolen.

As a nation, today’s society must invest in cyber security to execute military power, protect citizens information, and safeguard businesses.

Moreover, many organizations within the public and private sector heavily relies on technology to carry out their day to day operations. Those cyber technologies help make many difficult or tedious tasks easier to do and technology can also carry out many of those tasks more effectively and efficiently than humans can. However, cyber technologies are at risk of espionage, cyber attacks, or other crimes such as theft and fraud (Ammori & Poellet, 2010).

Cyber-terrorism is the convergence of terrorism and cyberspace. It is generally understood to mean unlawful attacks and threats of attack against computers, networks, and the information stored therein when done to intimidate or coerce a government or its people in furtherance of political or social objectives.

Cyber attack has been a huge problem for so many years and there have been a lot of attempts to stop it but there have not been enough resources for this to happen. This paper offers more top to bottom clarification of Cyber attack, reasons, dangers, and defenselessness. It talks about the impact on individual; gives situations of Cyber attacks lastly clarifies ways that people can keep themselves from being casualties of Cyber attack. This paper will give insights on how Cyber attack impacted the United States a year ago contrasted with now, climate it has expanded or diminished. It will likewise talk about how Cyber attacks have made more individuals careful about how they reveal data and the sort of sites they visit that lead to them being victims of cyber attack.

The immediate cyber threats to national security has been assessed as high. Cyber security threats are increasing in the number, type and sophistication of the threat. Although a detailed analysis is currently being developed, the ACSC’s Threat Report 2015 predicts the following attributes of cybercrime to increase in the coming decade.

Prevalent to the current trend now is the dependency of the society on Information technology and communication systems. Every aspect of human life is one way or the other linked and controlled by information technology tools. The importance of information technology cannot be over emphasized as its unavailability could lead to a form of disaster or the other. Pivotal infrastructures like finance, healthcare, education and security are driven by information technology. However, information technology and its benefits are accompanied by vulnerabilities and risks that can be exploited by people with the necessary technical skills. Individuals like ‘Hackers’ and ‘Cyber Terrorist’ can cause disruption to information systems, commit financial fraud and also attack computers and networks. These attacks and disruptions could result to violence against people and properties. In some cases, death, serious injuries and severe economic loss could occur as a result of these attacks.

Cybersecurity has only been around for a short time. In the short time it’s been around, it’s gone from a simple application process in security, to one of the most complicated things to get right in order to protect the internet. In the late 80’s the very first computer worm was created by Robert Morris. He released it into the internet in the early 90’s. With it, he shut down large portions of the internet. (Infosecurity Magazine) Back then, the internet didn’t play a large role in everyone’s lives, as it does today. But with that breach, it alerted people that we needed to come up with something to keep that from happening again, hence cybersecurity was born. Since then, cybersecurity has only become more complicated, as

How is that data and the systems on which that data resides or is transmitted kept secure. A big question. That’s where we need cyber security. Cyber security involves protecting the information and systems we rely on every day—whether at work or school and at home.

The possible threat posed by cyber terrorism has motivated considerable alarm. Many security experts have exposed the danger of cyber terrorists hacking into government and remote computer systems and service areas of progressive economies.

Cyber Security also called computer security and IT security, is the assurance of data from theft or any harm to the gadget, the product and information stored on hardware. It incorporates controlling physical access to the equipment and additionally ensuring against code or data injection or via network access.

Americans are becoming heavily dependent on modern day technology, which produce more vulnerability to cyber-attacks such as security breaches. Cyber security, also known as information technology security, is information security as applied to computers and computer networks. It is designed to protect networks, programs, computers and data from attacks. These attacks can lead to damages or unauthorized access to data. Computer security also includes protection from unplanned events and natural disasters. Cyber security main function is to guard computers, networks, programs and data from unintended or unauthorized access, change or destruction.

This paper proposes a policy directed examination on cyber threat, its scope and its impact on national security. It includes a profile of cooperation among criminals, terrorists and hostile organizations and discusses future of cybercrime in 2020. In recent years, “Information warfare” a new way of terrorism has become the major concern for information security specialists; terrorists might tamper with computers and electronic devices to commit secured information based threats to nations, to businesses and to individuals.
