Introduction to System Center Mobile Device Manager 2008 With today s mobile workforces, IT staff are required to manage an ever-expanding fleet of mobile devices and ensure that every device is authorized, has secure access and adequate permissions on the network, and does not compromise the security of corporate data. IT professionals need a flexible, end-to-end solution that helps them ease the process of securing and managing devices within a corporate network, while providing a more secure, single-point access for line-of-business (LOB) applications and corporate data. Mobile Device Manager is a comprehensive, reliable, and low-cost management solution that can be easily deployed into an enterprise s existing Microsoft infrastructure. Designed to address the three core requirements of IT professionals security, device management, and Mobile VPN Mobile Device Manager is a solution that helps administrators to efficiently address the growing need for increased security and manageability of Windows Mobile 6.1 devices within a network. Security Management Mobile Device Manager provides a security management platform for Windows Mobile 6.1 devices with more than 130 policy settings and built-in mechanisms that help prevent the misuse of corporate data. Administrators can lock down many areas of the Windows Mobile 6.1 devices, including certain communications and device functionality, while exercising significant control over the software that can be installed on devices. Device Management Mobile Device Manager is a simple and comprehensive solution for distributing software to Windows Mobile 6.1 devices and maintaining an inventory of devices in a complex organizational environment. Mobile Device Manager enables device enrollment through over-the-air (OTA) provisioning and bootstrapping. It also helps IT administrators streamline device management 2

Comprehensive reporting tools within Mobile Device Manager provide IT professionals with improved visibility of devices and help reduce the cost and complexity of managing devices within a corporate network. Mobile VPN Mobile Device Manager provides a single point for security-enhanced, behind-the-firewall access to corporate data and LOB applications. With Mobile Device Manager, administrators can facilitate security through a mobile-optimized, IPsec-based Mobile VPN link. The Mobile VPN link secures wireless communications between a mobile device and corporate servers by establishing an IPsec tunnel between the device and the Gateway Server. There is no dependency or requirement for SSL encryption. However, if there is SSL-encrypted traffic from another source (such as ISA Server 2006), Mobile Device Manager s IPsec tunnel can envelop this. (See the diagram at the end of this document for details.) This combination of IPsec VPN and SSL encryption lends a definite edge over other systems that generally rely on a single security barrier. With features such as fast reconnect and session persistence, Mobile VPN helps maximize user productivity in mobile environments. Mobile Device Manager 2008 SP1 Enhancements Mobile Device Manager SP1 helps provide organizations with even greater security management and device management with performance improvements, bug fixes, and enhanced feature updates. For added device management capabilities, Mobile Device Manager SP1 now offers the following enhanced features: Windows Server 2008 Compatibility: Mobile Device Manager SP1 is designed to run against a domain/forest running Windows Server 2008 Active Directory Domain Services. Multiple Instance: Mobile Device Manager SP1 with Multiple Instance enables organizations to deploy more than one instance of Mobile Device Manager within the same Active Directory Forest, and helps support enterprises deploying more than 30,000 mobile devices within a single forest. Enrollment Auto Discovery (available at Remote Console): Mobile Device Manager SP1 eases the user enrollment experience by allowing the user to initiate the enrollment process without entering complex Fully Qualified Domain Names (FQDN) or URLs. Enrollment Auto Discovery matches the user with the correct Mobile Device Manager instance, eliminating any guesswork and mismatch. PIN Reset (available at Remote Console): Mobile Device Manager SP1 allows users to request a PIN reset on their current device, which can be initiated by the IT helpdesk or directly by the user via a Self Service Portal (SSP). If the user is unable to unlock his or her device as a result of a forgotten or lost PIN, PIN Reset gets the user back up and running in a fast and predictable manner. Performance and Scalability: Mobile Device Manager SP1 increases system/server capacity to 40,000 users from Mobile Device Manager 2008 levels. Virtualization: Mobile Device Manager SP1 has Hyper-V support using hosted Windows Server 2003 for testing purposes. 3

4 IT Solutions for Mobile Challenges This section of the white paper underlines the benefits of Mobile Device Manager by presenting real-life scenarios pertaining to device management, security management, and Mobile VPN. Device Management with Mobile Device Manager In an enterprise network, IT administrators often have to rely on multiple management solutions to configure, manage, track, and target mobile devices in a corporate network.
