The type of Internet access policy that begins by blocking all services and then enables only safe and necessary services on an individual basis is known as a prudent policy. This approach is fundamentally conservative and focuses on security by default, ensuring that only explicitly permitted activities are allowed. By starting from a position of complete restriction, this policy effectively minimizes vulnerabilities and reduces the attack surface, as any potential threat must be actively allowed rather than simply ignored.

This method is particularly beneficial in environments where security is of utmost importance, as it compels a thorough evaluation of each service or application before it is granted access. This careful scrutiny helps in maintaining a secure network by ensuring that only essential and verified applications can interact with the network.

In contrast, other policies like a permissive policy allow more activities to take place without as much scrutiny, while an open policy typically provides broader access, and a paranoid policy might block services excessively without allowing for necessary functionality. Each of these alternatives may compromise efficiency or usability, while the prudent policy strikes a balance between security and functionality.
