- [2] When code runs in a "sandboxed environment" does this refer to a specific security technology? Explain briefly.
- [4] Define whitelists, blacklists, anomaly detection, and virtualization. Explain how they are four fundamental strategies in computer security.
- [2] Why is it harder to implement protection boundaries within a process, as compared to having an operating system implement protection boundaries? Explain.
- [2] Why are system calls a good interface for implementing security protections? Compare system calls to function/method calls in this context.
- [2] How do language runtimes (interpreted and just-in-time compiled) provide opportunities for enforcing security properties? Can these properties also be enforced when code is compiled (and at what cost)?
