Gramm-Leach-Bliley (GLBA) Act: A law passed in the United States that requires financial institutions to protect their customers' personal information. It is used to ensure that financial institutions handle personal data responsibly and that customers' information is secure. Examples of GLBA compliance include implementing security policies and procedures, conducting security audits, and providing security training to employees.

Graphical User Interface (GUI): A type of user interface that uses visual elements, such as icons and menus, to interact with a computer or device. It is used to make computer systems more user-friendly and intuitive, especially for non-technical users. Examples include using a GUI to access and manage files on a computer or to navigate and control a smartphone or tablet.

Gray Box: Gray box testing is a hybrid approach to software testing that combines elements of both black box and white box testing methodologies. Testers have partial knowledge of the internal workings of the application, which allows them to design test cases with more efficiency. Gray box testing is ideal for situations where understanding the context is essential, such as security penetration testing, where knowledge of system architecture enhances testing effectiveness.

Group-Based Privileges: A system of assigning permissions and access rights to users based on their membership in specific groups. This is commonly used in network security to control access to resources and ensure that only authorized users can access certain systems or data. Examples include assigning different levels of access to different departments within a company or allowing members of a specific group to access certain files or applications.

Guest escapes in virtualization: Guest escape vulnerabilities in virtualization refer to security flaws that allow a guest virtual machine (VM) to break out of its isolated environment and potentially access or manipulate the underlying host system. This type of vulnerability poses significant risks in multi-tenant virtualized environments, including cloud systems, where it could lead to unauthorized access to other VMs or sensitive host resources.

Guide for implementing the Risk Management Framework (RMF): A publication by the National Institute of Standards and Technology (NIST) that provides guidance on implementing the Risk Management Framework (RMF) for federal information systems. It is used in the government sector to ensure the security and compliance of information systems. For example, a government agency might use the guide to implement the RMF in its information technology systems.
