It discusses how the Internet, social media, smart phones and tablet computers have been playing a larger role in our daily lives. The majority of computers, whether in large corporations, in small businesses, or at home, are connected together in a network that creates a global community. People have become increasingly dependent on computer networks in many aspects of their lives — from communication, entertainment and financial transactions, to education and government services. Most people understand that global economic infrastructure is becoming increasingly dependent upon information technology, and no information system is secure in absolute terms. Cyber security has emerged as one of the essential discussion points in private lives of citizens, in government, in corporations and among nations, but most are not really aware of the finer details.It evaluates a combination of technologies and processes that are used to manage information-related risks, putting into context: the digitized nature of human life has an impact on homeland and national security with respect to a community, people or nation.

“The Cyber Citizen and Homeland Security” is not just about computer security, the protection of data in storage or while it is being processed; it is also about the protection of data in transit, and the application of data that causes changes in human life, societies, and nations. “The Cyber Citizen and Homeland Security” is a composite field involving computer science, mathematics, database and network management, strategy development, and policy issues. A common objective of work on Cyber Citizen and Homeland Security in these fields is to protect and defend information and information systems by ensuring their availability, integrity, authentication, confidentiality, and non-repudiation so that the right people can access the right information at the right time, enhancing security and safety of citizens in a digitized era. These are seen to be of pivotal importance to the security and defense apparatus of every nation and people.

Many computer users simply think that their firewall and antivirus software provide them with all the protection they need to keep their computers secure. However, as malicious hackers become more resourceful, and users add more and more information into a growing number of databases, there exists an increased exposure to hacker attacks, information espionage, and other security breaches. Information systems—operated by governments and commercial organizations—are vulnerable to attacks and misuse through their Internet connections. Workstations connected to the Internet are currently the most common targets of malicious hackers. As a result, information assurance and cyber security is a very serious concern for individuals, businesses, and governments. Not only do we need to be aware of how attacks are perpetrated, but we also need to learn how the systems can be protected against different attacks.
