Non-disclosure Agreement (NDA): A legal contract between at least two parties that outlines confidential material, knowledge, or information that the parties wish to share with one another for certain purposes but wish to restrict access from third parties. It's a legal way to protect sensitive information, preventing the revelation of insider information.

Non-Disclosure Agreement (NDA) - Bilateral: A legally binding contract in which both parties (the disclosing party and the receiving party) agree to keep certain confidential information shared between them secret. It is typically used when two parties are considering entering into a business relationship and want to protect their proprietary information. For example, if Company A and Company B are considering entering into a joint venture, they may both sign a bilateral NDA to protect the confidential information they share during the negotiations.

Non-Disclosure Agreement (NDA) - Multilateral: A legally binding contract in which multiple parties (the disclosing parties) agree to share certain confidential information with another party (the receiving party), but only for the purpose of evaluating a potential business relationship. It is similar to a unilateral NDA but involves multiple disclosing parties. For example, if Company A, Company B, and Company C are all considering entering into a joint venture, they may all sign a multilateral NDA to protect the confidential information they share during the negotiations.

Non-Disclosure Agreement (NDA) - Unilateral: A legal contract where one party agrees to disclose confidential information to another party under conditions that restrict its use, typically utilized in business contexts like negotiations or acquisitions.

Non-functional requirements: The criteria that judge the operation of a system rather than specific behaviors, typically referring to aspects such as performance, reliability, and security. These factors describe how a system should work rather than what it should do and can be critical to the system's functionality, performance, and overall user satisfaction.

Noninterference Model: The Noninterference Model is a formal security model designed to ensure that actions at a higher security level do not affect or interfere with the lower security levels within an information system. It's used to enforce confidentiality policies by preventing the flow of information from higher to lower security domains.
