Local Access

Applications running locally on the platform communicate with Intel AMT Release 2.0 and later releases in the same way that network applications do – WS-Management over SOAP over HTTP. As shown in the figure below, when a local application sends a message addressed to the local Intel AMT host name, the Local Manageability Service (LMS), which listens for traffic directed to the host name, intercepts the message and routes it to the Intel Management Engine Interface.

The LMS provides the following advantages:

   It unifies the local and network interfaces to both being WS-Management/SOAP/WSDL-based, simplifying the API.

   It capitalizes on all of the built-in advantages of HTTP including username and password authentication and the possibility to use HTTPS to add certificate-based authentication and encryption.

This interface incorporates a multi-threaded connection-based driver that communicates with the Intel ME, where the counterpart driver receives the information and passes it to the Intel AMT embedded IP stack.

Local applications can use third-party data storage to save information (for example, a software inventory) to non-volatile memory for future retrieval by a network management console.

Release 6.1 adds a powerful new default system user – the $$OsAdmin user –that enables a local application with OS Admin privileges to access many Intel AMT parameters without additional Intel AMT credentials and without performing setup and configuration. See Predefined Local System Users

Release 2.5 also incudes two other software components that run locally on the host that are essentially extensions of Intel AMT. They are:

   The Intel Management and Security Status application – IMSS

   The User Notification Service (UNS)

The IMSS provides status information to the local PC user about Intel AMT, including status messages, and an indication that Intel AMT is active. OEM documentation should describe the features of the IMSS. In Intel AMT Release 9.0 the UNS was combined with the Local Manageability Service (LMS) and is described in Local Manageability Service.
