The use of these libraries can help make your existing code more secure with relatively small changes, but nothing can stop you from doing something risky in your own code, or block you completely from misusing our code. Familiarity with these principles will help you understand the choices we made, but remember that there is no library, development process, document, or review that ensures completely secure code. When the Visual C++ team was designing the Safe Libraries, we used several principles to guide the design development. That's probably the best way for you to get a handle on the important changes. I encourage you to get a copy of the latest Beta and follow along with your own applications. The code samples here have been tested with a prerelease build of Visual Studio 2005. Finally, I'll present a migration guide to help you manage the transition of your code from earlier versions of Visual C++ to Visual C++ 2005. I will also briefly discuss how other security-related libraries work. I'll cover the architecture and design principles that guided the development of these libraries, and I have included specific examples of various ways to use them to write more secure code. This article describes the Safe C and C++ Libraries available in Visual C++ 2005. Extra debugging support has been added where it can help the most. Many functions have gained extra error checking and validation. New, safer functions have been added to supersede them. This extensive review mandated substantial changes that can improve the security and robustness of your apps.Ĭhanges include deprecation of functions that are known to be risky, such as strcpy. This upgrade resulted from a complete security review of the functions contained in the C Runtime (CRT) Library, Standard C++ Library (SCL), Active Template Library (ATL) and Microsoft® Foundation Classes (MFC). When Visual Studio® 2005 ships, you'll notice that it includes a major upgrade to the Visual C++® Libraries. Other Safety Improvements in Visual Studio 2005 This article uses the following technologies: Tips, tricks, and examples of using the new Safe Libraries.Security principles that drove their design.The Safe C and C++ Libraries in Visual C++ 2005.
