Information security's primary focus is the balanced protection of the confidentiality, integrity and availability of data also known as the CIA triad while maintaining a focus on efficient policy implementation, all without hampering organization productivity. This is largely achieved through a structured risk management process that involves:. To standardize this discipline, academics and professionals collaborate to offer guidance, policies, and industry standards on password, antivirus software, firewall, encryption software, legal liability, security awareness and training, and so forth. This standardization may be further driven by a wide variety of laws and regulations that affect how data is accessed, processed, stored, transferred and destroyed.

Computer security , cybersecurity  or information technology security IT security is the protection of computer systems and networks from information disclosure, theft of or damage to their hardware , software , or electronic data , as well as from the disruption or misdirection of the services they provide. The field is becoming increasingly significant due to the increased reliance on computer systems , the Internet  and wireless network standards such as Bluetooth and Wi-Fi , and due to the growth of "smart" devices , including smartphones , televisions , and the various devices that constitute the " Internet of things ". Owing to its complexity, both in terms of politics and technology, cybersecurity is also one of the major challenges in the contemporary world.

This chapter discusses security policies in the context of requirements for information security and the circumstances in which those requirements must be met, examines common principles of management control, and reviews typical system vulnerabilities, in order to motivate consideration of the specific sorts of security mechanisms that can be built into computer systems—to complement nontechnical management controls and thus implement policy—and to stress the significance of establishing GSSP. Additional information on privacy issues and detailing the results of an informal survey of commercial security officers is provided in the two chapter appendixes.
IT security is a set of cybersecurity strategies that prevents unauthorized access to organizational assets such as computers, networks, and data.
