What type of admin should the MID Server typically operate as?

The MID Server should typically operate as a Local Admin. This is because the MID Server is responsible for facilitating secure communication between ServiceNow and external systems or data sources within a local network, and it operates under the principle of least privilege.

By functioning as a Local Admin, the MID Server can perform necessary tasks such as discovering network services, collecting data, and interacting with various applications without having more extensive permissions than are required for its functions. This approach enhances security by minimizing the risk of potential vulnerabilities that could arise from broader administrative access.

Moreover, Local Admin privileges allow the MID Server to perform its role effectively within the specific environment it is installed in, while still maintaining a controlled access level that aligns with organizational security policies. In contrast, other admin roles, such as Global Admin or Super Admin, would grant broader permissions that are unnecessary for the typical operational needs of a MID Server, potentially exposing the system to greater risk.
