2. © SERG Reverse Engineering (REportal) Introduction Software Engineering community has produced many tools. Challenges: –Usability –Ease of Installation –Interoperability –Copyrighted works (limited distribution) DMCA (United States)

3. © SERG Reverse Engineering (REportal) Introduction Cont’d We’ve faced these challenges with our own tools: –CIAO Acacia (C/C++ Analysis) Chava (Java Analysis) –Bunch (static clustering) –Form (dynamic analysis) –Graphviz (graph visualization) –…

4. © SERG Reverse Engineering (REportal) Background: Tools Source code analysis: –Visual Studio, CIAO, … Design Extraction: –Bunch, Rigi, ARCH, … Visualization: –Graphviz, Rigi, Tom Sawyer, …

5. © SERG Reverse Engineering (REportal) Standardization Attempts Difficult—tools address different needs Not all tools are portable to all platforms –“Java is write once debug many times” (http://www.lionhrtpub.com/orms/orms-2-99/cyberspace.html)http://www.lionhrtpub.com/orms/orms-2-99/cyberspace.html Not all interfaces are fully exposed Our proposed solution: REportal

21. © SERG Reverse Engineering (REportal) REportal Architecture n-tiered Java servlet

22. © SERG Reverse Engineering (REportal) Extensibility Adding a tool is a two-stage process: 1.Tool is added to the server’s tool set 2.Servlet is extended to include the tool among its set of services In the future, this process may be automated via a wizard-like facility

23. © SERG Reverse Engineering (REportal) Future Work Integrate more reverse-engineering tools into REportal Integrate dynamic analysis Security architecture –Sandbox for running user Makefiles and applications C/C++ support Distributed/multi-platform support REportal distribution for remote site use

24. © SERG Reverse Engineering (REportal) Conclusions Advantages –RE services provided via consistent web-based user interface –No need to be aware of platform integration or interoperability issues –Latest versions of underlying tools always available –No software installs needed
