16.2.1.3 OCS - Security Considerations

You must configure an external application for Microsoft Office Communications Server connections so that users can supply credentials to authenticate themselves on the OCS server. With a secured application, users get presence status. With OCS, if security is required, then OCS should be on a private trusted network. OCS provides an option for changing external credentials, which works as an alternative to using an external application. A logged-in user can click any Presence tag and select Change Credentials from the menu. For more information, see Section 16.3.1, Registering Instant Messaging and Presence Servers Using Fusion Middleware Control.
