Cyber Security or the Security of Information Technology (IT Security) are regarded as techniques which are used to protected computers, hardware, software, networks, programs and electronic data from unauthorized access or attacks which are aimed for exploitation, and also from disruption or misdirection of the services they offer. These cyber-attacks are often aimed to change, access, or destroy sensitive information; interrupting normal business processes or extorting money from users. Implementing efficient cyber security measures is particularly demanding today in that there are more devices than people, and attackers are becoming more innovative.
Based on three Principles of Cyber Security (Confidentiality, Integrity, and Availability) that are growing in significance because of increasing dependence on the Internet, computer systems, and wireless networks like Bluetooth and Wi-Fi, and due to the growth of smart devices, including smartphones, televisions and the various tiny devices that comprise the Internet of things (IoT). Because of its complexity, both in respect of technology and politics, it is also one of the main challenges of the contemporary world.
In today’s connected world, each organization gets benefits from advanced cyber defense programs. At an individual level, a Cyber Security attack can result in everything from identity theft, to extortion attempts, to the loss of important data, or research documents. Everyone depends on critical infrastructure such as hospitals, universities, institutions, power plants, and financial service companies. Securing these and other organizations is vital significant to keeping our society functioning. In an organization, the people, processes, and technology must all complement one another to generate a successful defense from cyber-attacks.
