BinaryRelease Bits Assurance

Binary/Release Bits Assurance

Unless you are working with open-source software, it is usually in everyone's best interest to be 100 percent sure that all the release bits (the binaries and files) in your product came from your development team. Therefore, you need some kind of mechanism to verify or enforce this condition. Several tools are available that can modify binaries after they have been released. A malicious person does not need access to the source code. He can just use this tool, which is usually easily accessible via the Web, and "hack" the binary to perform some unwanted behavior. The best way to prevent this from happening is to integrate software restriction policies. Software restriction policies are a new feature in Microsoft Windows XP and Windows Server 2003. This important feature provides administrators with a policy-driven mechanism for identifying software programs running on computers in a domain, and it controls the ability of those programs to execute. Software restriction policies can improve system integrity and manageability which ultimately lowers the cost of owning a computer. As a result, no one will be able to copy a hacked or modified binary over the original product.

You should also make sure that you have a good versioning scheme so that you can track the build number associated with a particular release. We talked about this in great detail in Chapter 8, "Versioning."
