The beta version of Microsoft's Attack Surface Analyzer is now replaced with version 1. Microsoft's SDL team releases version 1.0 of the tool as a continuation of its effort to provide tools that hardened the stability and security of Windows environments. The tool helps software developers, Independent Software Vendors (ISVs) and IT Professionals understand changes in Windows systems' attack surface resulting from the installation of new applications. The tool is available for both 32 & 64 bit systems and a stand-alone wizard to help guide users through the scanning and analysis process; a command-line version supports automation and older versions of Windows, and assists IT professionals as they integrate the tool with existing enterprise management tools.
The Attack Surface Analyzer enables developers to view changes in the attack surface resulting from the introduction of their code on to the Windows platform and IT Professionals to assess the aggregate attack surface change by the installation of an organization's line of business applications.
