What is SHE?
- SHE: Software Hardening Environment.
- Tool for fault-tolerant software development.
- It allows the design and implementation of software-based mitigation techniques, which can be automatically applied into programs.
- The hardening (protection) strategy is based on code transformation rules at low level, i.e., assembly code.
- It permits to apply software-based fault tolerance techniques in a selective way, protecting only the most critical parts of the program. As a result,
there is a significant reduction in overheads, and at the same time, designers have more flexibility to find the best trade-offs among the system requirements.
- Multiplatform: tested in Linux and Windows.
