Does anyone tell me how to block system calls within a program, please? I am building a system which takes a piece of C source code, compiles it with gcc and runs it. For security reasons, I need to prevent the compiled program from calling system calls. Is there any way to do it, from the source code level (e.g. stripping the header files of gcc, detecting malicious external calls, ...) to the executable level?
