BackgroundKernel vulnerabilities are a major current practical security problem, as attested by the weaknesses and flaws found in many commodity operating system kernels in recent years. Ever-growing code size in those projects, due to the addi- tion of new features and the reluctance to remove legacy support, indicate that this problem will remain a severe sys- tem security threat in the foreseeable future. In order to measure precisely the attack surface of the kernel, that is the amount of privileged code accessible from a given user or application through system calls, we consider using the call graph of kernel functions. This will allow us subsequently to precisely measure the efficiency of attack surface reduc- tion tools such as ktrim, which disallow the execution of unnecessary kernel functions by unprivileged applications. The project will be in collaboration with IBM Research in Zurich. Project Goals
