What is the purpose of an Allow List in security settings?

The purpose of an Allow List in security settings is to define who can access specific elements. An Allow List, also known as a whitelist, explicitly specifies which entities (such as users, devices, or applications) are granted permission to access certain resources or data, thereby enhancing security by limiting access to only those who are authorized. This proactive approach helps organizations ensure that only trusted entities can engage with their systems, reducing the risk of unauthorized access or potential security breaches.

By focusing on who is allowed rather than who is banned, an Allow List creates a more controlled and secure environment. This contrasts with blocking access, monitoring breaches, or logging activities, which serve different security purposes.
