The concept of site whitelist corresponds to "blacklist".

By identifying whether processes or files in a system have approved attributes, public process names, file names, publisher names and digital signatures, whitelisting technology can enable enterprises to approve which processes are allowed to run in a specific system. Some vendor products only include executable files, while others include scripts and macros, which can block a wider range of files. Among them, an increasingly popular whitelisting method is called "application control", which focuses on managing the behavior of endpoint applications.

White list is to set users who can pass, and users outside the white list cannot pass. Blacklist refers to users who can't pass the setting, and users outside the blacklist can pass.
