What type of connections does the MID Server use for communication?

The MID Server utilizes SOAP over HTTPS (port 443) for communication. This method is chosen because it ensures secure data transmission, leveraging the encryption capabilities of HTTPS to protect the information being sent between the MID Server and the ServiceNow instance. By using HTTPS, the communication is safeguarded against potential eavesdropping and tampering, which is critical when handling sensitive configuration and discovery data.

This secure communication channel is essential for the MID Server to effectively perform its role in ServiceNow Discovery, as it needs to interact with various devices and applications within an organization's infrastructure while adhering to security best practices. The use of SOAP as a protocol allows the MID Server to send structured data requests and receive responses in a standardized format, facilitating seamless integration with the ServiceNow platform.

The other options, while potential communication methods in broader contexts, do not meet the security and protocol requirements necessary for MID Server operations.
