Developing security-critical systems in a way that makes sure that the developed systems actually enforce the desired security requirements is difficult, as can be seen by many security vulnerabilities arising in practice on a regular basis. Part of the difficulty is the transition from the security requirements analysis to the design, which is highly non-trivial and error-prone, leaving the risk of introducing vulnerabilities. Unfortunately, existing approaches bridging this gap largely only provide informal guidelines for the transition from security requirements to secure design.
We present a
method
to systematically develop structural and behavioral UMLsec design models based on security requirements. Each step of our method is supported by
model generation rules
expressed as pre- and postconditions using the formal specification language OCL. Moreover, we present a concept for a
CASE tool
based on the model generation rules. Thus, applying our method to generate UMLsec design models supported by this tool and based on previously captured and analyzed security requirements becomes systematic, less error-prone, and a more routine engineering activity.
We illustrate our method by the example of a patient monitoring system.
