allowlisting

**allowlisting**

Allowlisting is the practice of explicitly permitting specific entities-such as IP addresses, email addresses, applications, or users-to access a system or resource. Unlike traditional blocking approaches that deny everything except what’s allowed, allowlisting focuses on creating a trusted list that ensures only verified and approved items can interact with the environment. This approach is commonly used in cybersecurity, network management, and email filtering to enhance security by reducing exposure to unauthorized or potentially harmful access.
