NIST SP 800-88: A special publication by the National Institute of Standards and Technology providing guidelines for media sanitization. It details how to properly clear, purge, and destroy data on different types of media to prevent unauthorized disclosure of sensitive information.

Node: Any device that can send, receive, or forward information over the network. This could include computers, printers, switches, or any other device connected to the network. Nodes play an essential role in network infrastructure and the distribution of data, where each one serves as a connection point within the network.

Noise: In the context of IT and cybersecurity, noise refers to irrelevant or extraneous information or signals that can obscure or interfere with the transmission and processing of data. Digital noise can be caused by electrical interference, signal crosstalk, or data corruption and may result in degraded system performance or errors in data communication.

Nonce: A randomly or pseudo-randomly generated number that is used only once in a communication protocol. They are often employed to ensure data freshness and to prevent replay attacks where an attacker might attempt to replay a previous communication or transaction, leading to potential data breaches or fraudulent transactions.

Noncompete Agreement: A legal contract between an individual and an entity (usually between an employee and their employer) that restricts the individual from entering into competition against the entity during and after the employment period. This often includes limitations on working for competitors, starting a similar business, or sharing proprietary and sensitive information that could compromise the competitive advantage of the initial entity.

Non-disclosure: An agreement that legally binds parties to secrecy, ensuring that sensitive information is not disclosed to unauthorized individuals. Non-disclosure agreements (NDAs) safeguard proprietary information, trade secrets, and other confidential data, critical in business negotiations and partnerships.
