With the growing use of the internet by people, protecting important information has become a necessity.  A computer that is not having appropriate security controls can be infected with malicious logic and thus any type of information can be accessed in moments. Number of infected Web Pages and malicious websites can be seen every day that infects the computer and allow hackers to gain illegal access to other computer systems. Hacking of important data, network outages, computer viruses and other cyber related threats affect our lives that range from minor inconvenience to serious incidents. Cyber threats can be caused due to negligence and vulnerabilities, or unintentional accidents. The main objectives of such type of system attackers or hackers are to steal confidential information, to make illegal monetary transactions, to destroy or to change data and the like. System attackers can be terrorists, crackers or recreational hackers. They have a variety of tools that can harm or infect the computer; usually they use malicious logic or virus to gain unauthorized access to a computer. Opening email attachments that carry the virus, clicking malicious links or websites or unintentionally downloading a dangerous program are common ways through which a computer can be infected and data can be stolen. As the number of data networks, digital applications, as well as internet and mobile users are growing, so do the chances of cyber exploitation and cyber crimes. Even a small mistake in securing data or bad social networking can prove to be extremely dangerous. If accounts are not properly secured, it makes easier for hackers or unauthorized users to spread viruses or social engineered attacks that are designed to steal data and even money.Such types of issues highlight the need for cyber security as an essential approach in protecting and preventing data from being used inappropriately.In simple language, Cyber Security or Information technology security means protecting data, networks, programs and other information from unauthorized or unintended access, destruction or change. It encompasses all the mechanisms and processes that protect digital equipment, information and records from illegal or unintended access, manipulation or destruction. In today’s dynamic environment, cyber security has become vital for individuals and families, as well as organizations (such as military, government, business houses, educational and financial institutions, corporations and others) that collect and store a wide range of confidential data on computers and transmit that to other computers across different networks. For families, protection of children and family members from cyber crime has become substantially important.
