********************************************************************** * * Copyright (c) 2009 - 2010 Intel Corporation. * Intel(R) Active Management Technology (Intel(R) AMT) User Notification Service (UNS) * ********************************************************************** ********************************************************************** * 1. Overview ********************************************************************** Intel(R) AMT is able to write user notifications to the local host OS event log for the purpose of notifying end users of predefined events, such as when critical System Defense policies are applied by the ME FW. Intel provides documentation on how the ISV can extract these events from the event log for use in their applications. The UNS also provides NAC (via a plugin) and NAP functionality. To enable NAP, see the installation Note below. ********************************************************************** * 2. System Requirements ********************************************************************** The UNS is supported on the following operating systems: - Windows* XP SP1/2 (32 bit) - Windows Vista* (32 and 64 bit) ********************************************************************** * 3. Install steps ********************************************************************** UNS.exe is found in the \LMS_SOL directory. To install the UNS, run setup.exe and note the following installation circumstances: 1) TLS: If Intel AMT is configured to work with TLS then any application that wants to communicate with the Intel AMT PC must be able to verify the server certificate that intel AMT sends. To do that, the root certificate (which signed the Intel AMT certificate) must be installed (by the IT administrator) in Windows’s trusted root certificate store. Being a service, the UNS runs in the system context (not as a user process), and as such does not see the same certificate store. For the UNS to have access to the root certificate, it must be installed using the “mmc” tool, as is specified in step 4 in: http://support.microsoft.com/kb/901183/ 2) Mutual Authentication TLS: If Intel AMT is configured to use mutual authentication TLS for local (this can be set separately for remote and local), then when local applications try to connect, Intel AMT will require from them a client certificate for verification. This client certificate must be installed in Windows’s personal certificate store. Again, as was the case with the server certificate, the UNS being a service means that the IT administrator must install the client certificate using steps 1-3 of the above link. Furthermore the UNS must be told which client certificate in the store to actually use,which can be done with the following command line argument: “-cert ”. (Services can receive arguments either on the command line (using the “sc” command) or in the graphical service controller window.) 3) HTTP Credentials: Regardless of the TLS situation, the UNS uses SOAP calls to Intel AMT and requires credentials. The UNS calls two SOAP services in Intel AMT: User Notification and Endpoint Access Control. These two realms might have different access privileges (that is, different users can be part of these realms). By default there is no need for credentials to access the above two realms for the UNS to work. However, the administrator can decide to block this anonymous access and mandate credentials for one or both of the above realms. This can be done using the SetRealmAuthOptions SOAP command in the Security Administration interface. If credentials are needed for these realms, they need to be passed to the UNS as arguments: “-unsUser -unsPass ” for the User Notification realm, and “-eacUser -eacPass ” for the Endpoint Access Control realm. A property of the above credentials is that the UNS saves them for the next time it is run. This means that the UNS can be started once with the credentials as arguments, stopped, and then restarted without the credentials and they will still be used (as long as Intel AMT is configured to require them). This allows the administrator to run the UNS without the credentials showing in the process table as the UNS process’s arguments. Note: Enabling NAP is currently a manual process. To enable NAP, ensure that the UNS is not running, then run the following command: "UNS.exe RegisterNap". Restart the UNS. To disable the NAP access, ensure that the UNS is not running, then run: "UNS.exe UnregisterNap" ********************************************************************** * 4. UNS Registry Configuration Parameters ********************************************************************** You can configure the following parameters in the HKEY_LOCAL_MACHINE\SOFTWARE\Intel\IntelAMTUNS\ConfigData registry key of the Intel AMT: AMTStatusPollingInterval: The interval in seconds between event polling requests sent from the UNS to the Intel AMT. Minimum value = 1; Maximum value = 86400 (24 hours); Default = 10 GetPostureInterval: The interval in seconds between posture information requests sent from the UNS to the Intel AMT. Minimum value = 1; Maximum value = 86400 (24 hours); Default = 360 ********************************************************************** * 5. Uninstall procedure ********************************************************************** Click Start > Control Panel, double-click Add or Remove Programs. Select Intel(R) Active Management Technology and click Remove. Note that this will also remove LMS, SOL, etc. **************************************** * INTEL SOFTWARE LICENSE AGREEMENT * (OEM / IHV / ISV Distribution & * Single User) **************************************** IMPORTANT - READ BEFORE COPYING, INSTALLING OR USING.
