- Updating The process of applying patches, bug fixes, or enhancements to a system or software. Regular updates are crucial for maintaining system security as they often contain fixes for known vulnerabilities that could otherwise be exploited. The updating process should be managed carefully to minimize the potential for introducing new vulnerabilities or disrupting system functionality.
- Uploading The process of transferring data from a local device to a remote server or cloud storage. It is used to share files or backups or to access them from multiple locations. Examples include uploading a file to Dropbox, uploading a photo to Instagram, or uploading a video to YouTube.
- Uptime InstituteAn organization that provides standards and certifications for data center reliability and efficiency. Their guidelines focus on both physical and logical components of data center operations, and adherence to their standards can significantly enhance the reliability and security of data center services.
- URL filtering A technique used to block access to certain websites based on their URLs. It's commonly used to prevent access to malicious websites or to enforce policies against accessing inappropriate or non-work-related content. This can reduce the risk of malware infection and data leakage, as well as increase productivity.
- USA PATRIOT Act of 2001 Officially the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act, it's a legislative act signed into law to enhance law enforcement investigatory tools following the September 11 terrorist attacks.

- USB (Universal Serial Bus) A standard type of connection interface used for transferring data and connecting devices. USBs can pose a security risk due to their ability to carry and transmit data and malware. Proper management, including limiting usage, disabling unnecessary ports, and scanning for malware, can mitigate these risks.
- User A user is an individual or entity that interacts with a computer system or service. In cybersecurity, a user can be an administrator, an employee, or a customer, each with varying levels of access and privileges. Ensuring the security of user accounts and data is fundamental to protecting against unauthorized access and breaches.
- User-assigned privileges The specific rights and permissions granted to a user to access and use certain resources or perform certain actions.

Examples include allowing a user to read or write to a specific file or to access a particular network or database. This can also be referred to as "user permissions" or "access rights."
- 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.
