Hyper-V Attack Surface Reference Workbook
The Windows Server 2008 Security Guide includes a spreadsheet you can download that lists all the attack surfaces for Windows Server 2008. This guide was initially published before Hyper-V role RTM. When the Security Guide is updated, a new worksheet in the Attack Surface Reference Workbook will be added that lists the attack surfaces for Hyper-V. Until then, you can find the same information in the Hyper-V Attack Surface Reference Workbook, available for download at http://download.microsoft.com/download/8/2/9/829bee7b-821b-4c4c-8297-13762aa5c3e4/Windows Server 2008 Hyper-V Attack Surface Reference.xlsx
