Government and industry increasingly rely on modern information systems (IS) for mission successes. But their critical IS must survive in hostile environments; thus, mission owners need systems security engineers to build systems that are secure against real-world attacks but not over-engineered against a particular one. By understanding which attacks are most likely and which risks are most serious, mission owners can make cost-effective countermeasures decisions. We describe a systems security-engineering methodology for enumerating system attacks, assessing risks, and choosing countermeasures that best mitigate the risks.
