- Rust provides memory safety but requires discipline for application security.
- The Security Trinity: Type Safety, Error Safety, Secret Safety.
- Use semantic types to prevent bugs like transferring money to the wrong place.
- Avoid panics in financial systems to prevent DoS attacks.
- Handle overflows explicitly to avoid silent money corruption.
- Use cryptographic randomness for security-critical operations.
- Zeroize secrets to prevent them from lingering in memory.
- Avoid logging sensitive information.
- Use parameterized queries to prevent SQL injection.
- Offload CPU-intensive work to thread pools in async contexts.
- Release locks before await points to prevent deadlocks.
- Ensure cancellation safety in async operations.
- Verify authorization and ownership in smart contracts.
- Use deterministic functions in blockchain contexts.
- Document safety invariants for unsafe blocks.
- Enable security-focused compiler and build settings.
- Write property-based tests to verify security invariants.
- Implement layered security checks in critical functions.
- Follow best practices for secure Rust development.
