Visual Studio offers a convenient Integrated Development Environment (IDE) for managing solutions and their settings. The section called "Visual Studio Options" discusses options which should be used with Visual Studio, and the section called "Project Properties" demonstrates incorporating those options into a solution's project. The table below lists the compiler and linker switches which should be used under Visual Studio. Refer to Howard and LeBlanc's Writing Secure Code (Microsoft Press) for a detailed discussion or _Protecting Your Code with Visual C++ Defenses_ in Security Briefs by Michael Howard. In the table below, "Visual Studio" refers to nearly all versions of the development environment, including Visual Studio 5.0 and 6.0. For a project compiled and linked with hardened settings, those settings can be verified with BinScope. BinScope is a verification tool from Microsoft that analyzes binaries to ensure that they have been built-in compliance with Microsoft's Security Development Lifecycle (SDLC) requirements and recommendations. See the _BinScope Binary Analyzer_ download page for details. VStudioWarningOptionsTable a) See Jon Sturgeon's discussion of the switch at _Off By Default Compiler Warnings in Visual C++_. a) When using /GS, there are a number of circumstances which affect the inclusion of a security cookie. For example, the guard is not used if there is no buffer in the stack frame, optimizations are disabled, or the function is declared naked or contains inline assembly. b) #pragma strict_gs_check(on) should be used sparingly, but is recommended in high risk situations, such as when a source file parses input from the internet.
