Deny List: A security measure that specifies certain entities — such as software applications, email addresses, users, or IP addresses — that are blocked or denied access to a system. It’s a form of access control used to improve system security by explicitly refusing entry to potential threats and is the opposite of an allow list, which permits access only to entities that have been deemed safe.
