Integrate automated security verification tools and methodologies into the design workflow for complex systems to proactively address vulnerabilities.

How to apply

When designing critical systems, use modeling languages like SysML and employ automated tools that can verify security properties against potential attack scenarios.

Project actions

01When defining security requirements for your design project, be specific and measurable.
02Consider how potential users or adversaries might interact with your design in unintended ways.

Method & Evidence

AimTo develop a practical and formal framework for assessing security risks and verifying security requirements in systems modeled using UML/SysML behavioral diagrams.

MethodFormal verification and probabilistic model-checking.

ProcedureA novel approach was developed to automatically verify system security based on security requirements and probabilistic adversarial interactions with system models. Stochastic security templates and a catalogue of attack patterns were used to build a library of attacks. The interaction between attack scenarios, composed diagrams, and instantiated security properties was analyzed using a probabilistic model-checker to quantify security risk. Optimizations were employed to handle verification scalability.

ContextSoftware and systems engineering, particularly for complex, interconnected systems.

Variables

IVSystem model complexity, defined security requirements, attack scenarios.

DVQuantified security risk, verified security properties.

CVModeling language (SysML), type of behavioral diagram (activity diagrams), probabilistic model-checker used.

Strengths & Limitations

Strengths

+Provides an automated approach to security verification.
+Offers a quantitative measure of security risk.
+Addresses scalability challenges for large systems.

Limitations

The complexity of setting up and running formal verification tools can be a barrier.

Reliability & validity

The reliability of the framework depends on the consistency of the model-checker's results. Validity is supported by testing on benchmarks, but real-world system complexity may differ.

Think critically

How might the complexity of real-world attack vectors be fully captured in a formal verification model?

Design Principles
