Patterns for the secure and reliable execution of processes

摘要: The controlled interaction of processes in a computing environment is fundamental for its security and reliability. Processes can be attacked by other or external clients, errors one process propagate to others. We show here three patterns that help provide secure reliable execution although they need complemented with patterns. They include Protected Entry Points, which control the correct use entry points according their signatures (type length parameters); Protection Rings, calls between processes, enforcing constraints on level trust processes. Finally, Multilevel Secure Partitions (MSP) pattern, confines system partition has specific confidentiality integrity level.
