Security Engineering - Interaktive Studienpläne der TU Ilmenau

The module is completed with an alternative exam, performed in several parts over the course of the semester. After the end of the lecture period, no further examination is required. The final grade is determined by completing

- home assignments and classroom assignments (25%)

- three specialized workshops with creative, hands-on tasks (50%)

- one final project workshop (25%).

Students are able to understand and discuss the methodical
steps of model-based security engineering. They can describe well-known,
fundamental formal models as well as revise and refine them for a selected
application scenario. They can apply analysis paradigms to design and implement
algorithms for validating scenario-specific security properties. They can
describe the purpose of security model specification languages, compare
different languages for specific application scenarios and apply them to a
given model. They can discuss security requirements for a complex scenario,
derive a formal security model from them, and implement this model in a
security architecture during the final workshop.

This module is an advanced class on systems security. It focuses on methodological engineering of security properties of IT systems based on formal security models. In an early stage of the engineering process formal security models are used for the precise and unambiguous representation of security policies which then are analyzed by static model checking and simulative model execution. Successful models afterwards are transformed via specification languages into executable code which finally is integrated into a system's TCB.

The class is organized in lectures and workshops; while theoretical knowledge is imparted in traditional lectures and exercises, practical skills are trained in a total of five workshops. Course topics are:

• Requirements Engineering
• Model Engineering
• advanced security models  (take-grant model, schematic protection model, typed-access-matrix model, role-based access control (RBAC), attribute-based access control (ABAC)
• model composition
• model analysis
• Specification Engineering
• specification languages
• workshop on language design
• workshop on language implementation and compiler
• TCB Engineering
• TCBs
• security architectures
• Security Engineering
• workshop: a complete security engineering project
