User awareness: The knowledge and understanding of security risks and best practices among users of a system or network. It is an essential element of an effective security program, as users are often the first line of defense against threats. Examples include educating users on password security, phishing scams, and safe browsing habits.

User Datagram Protocol (UDP): A type of internet protocol that allows applications to send and receive data without the need for an underlying connection-oriented protocol. It is used in applications that require low-latency or real-time data transmissions, such as online gaming and voice-over IP. Examples include Skype, online gaming, and video conferencing.

User ID: A unique identifier assigned to a user to authenticate their identity when accessing a system or network. It is used in authentication systems to verify a user's identity and grant them access to appropriate resources. Examples include a username, employee ID, and social security number.

User Mode: An operating state in modern computer systems that limits the access rights of software applications, preventing them from directly interacting with hardware or system resources. This mode maintains system stability and security by restricting application access to sensitive areas of the operating system.

User provisioning: The process of creating and managing user accounts within a system or network. It is used to ensure that only authorized users have access to the appropriate resources and to maintain an accurate and up-to-date record of user permissions. Examples include creating new user accounts, assigning roles and permissions, and disabling inactive accounts.
