Design takeaway

When implementing security features that monitor program execution, prioritize fine-grained instrumentation to minimize performance impact and maximize effectiveness.

How to apply

When designing software that requires strict control-flow integrity, consider implementing instrumentation techniques that precisely define valid execution paths rather than relying solely on broader hardware mechanisms.

Project actions

  • 01Consider how to precisely define the allowed 'paths' or 'states' within your design.
  • 02Think about how to measure and minimize the 'overhead' or 'cost' of your design's features.

Method & Evidence

AimHow can program code instrumentation be used to improve the precision and reduce the overhead of hardware-assisted control-flow integrity enforcement mechanisms?
MethodSystematic Design and Implementation
ProcedureThe researchers designed and implemented a control-flow enforcement mechanism called FineIBT. This involved instrumenting program code to reduce the set of valid targets for indirect forward-edge transfers, specifically on the x86-64 architecture. The implementation was integrated with the Linux operating system and the LLVM toolchain. Performance and security were evaluated using standard benchmarks and a CFI benchmarking suite.
