ProblemOperating Systems have to handle an open-ended number of bad system-calls without crashing.
- Generate random bytes
- Turn off system-level exception handling
- Run the system using the random bytes as input to system calls
- If it crashes, harden the code to handle it
- These are the interfaces where the user of the code enters input and you have to trust them to enter valid input.
Trust Boundaries have to be tested with as many inputs outside the domain as possible
