31.9 Research Issues

The first research issue has to do with analysis of code. How can one analyze programs to discover security flaws? This differs from the sort of analysis that is performed in the development of high-assurance systems, because the program and system are already in place. The goal is to determine what, and where, the problems are. Some researchers are developing analysis tools for specific problems such as buffer overflows and race conditions. Others are using flow analysis tools to study the program for a wide variety of vulnerabilities.

Related to this issue is the development of languages that are safer with respect to security. For example, some languages automatically create an exception if a reference is made beyond the bounds of an array. How much overhead does this add? Can the language use special-purpose hardware to minimize the impact of checking the references? What else should a language constrain, and how should it do so?
