A white list is a curated list of approved or trusted items, entities, or individuals that are granted special privileges or access. This term is often used in the context of technology, where a white list can refer to a list of safe websites, email addresses, or software programs that are allowed to bypass security measures. In contrast to a black list, which contains items that are banned or restricted, a white list serves as a safeguard against potential threats or unwanted content. The concept of a white list can also be applied in other areas, such as finance, where it may refer to a list of pre-approved investments or clients. Overall, a white list serves as a reliable filter, ensuring that only authorized and trusted elements are permitted.
