Near Field Communication (NFC): A short-range wireless communication technology that allows devices to exchange data over distances of less than 4 inches. It is used in mobile devices and other smart devices to enable contactless transactions, data sharing, and access control. Examples of NFC applications include mobile payments, public transit systems, and access control for buildings and vehicles.

Need To Know: A principle in the control of access to confidential information. The concept suggests that information should be provided only to those individuals who absolutely need it to perform their responsibilities. The need-to-know principle helps to enforce the confidentiality of sensitive information, limit the number of people with access to this type of data, and reduce the risk of unauthorized disclosure or misuse of the information.

Need to Know Determination: The "Need to Know Determination" is the process by which organizations assess and decide which individuals need access to specific information to fulfill their job duties. It's an aspect of access control focused on minimizing the risk of unauthorized information disclosure by granting access only to those with a justified requirement for that information.

Negative-list: A negative-list, also known as a denylist or blacklist, is an access control mechanism that specifies entities, such as user accounts, email addresses, or IP addresses, which are explicitly denied access or privileges within a system or network. This approach contributes to safeguarding against unauthorized access and securing systems from potential attackers or harmful activities.

Netflix Chaos Monkey: A tool used by the streaming company Netflix to test the resilience of its systems by randomly shutting down individual services and components. This helps to ensure that the system can continue to operate even in the face of failures and disruptions.

Network: A group of interconnected devices that can communicate and exchange data with each other. Used in computer systems, telecommunications, and other industries to facilitate communication and sharing of resources. Examples include local area networks (LANs), wide area networks (WANs), and virtual private networks (VPNs).
