Description:
Security engineering is an evolving discipline that unifies two important areas: software engineering and security. Software Engineering addresses the development and application of methods for systematically developing, operating, and maintaining, complex, high-quality software.
Security, on the other hand, is concerned with assuring and verifying properties of a system that relate to confidentiality, integrity, and availability of data.

The goal of this class is to survey engineering techniques for developing secure systems. We will examine concepts, methods, and tools that can be applied within the different activities of the software development process, in order to improve the security of the resulting systems.

Modules taught:

1. Introduction
   - Introduction of Infsec group and speakers
   - Security meets SW engineering: an introduction
   - The activities of SW engineering, and where security fits in
   - Overview of this class
2. Requirements Engineering: Security Requirements and some Analysis
   - overview: functional and non-functional requirements
   - use cases, misuse cases, sequence diagrams
   - safety and security
   - FMEA, FTA, attack trees
3. Modeling in the design activities
   - structure, behavior, and data flow
   - class diagrams, statecharts
4. Model-driven security for access control (design)
   - SecureUML as a language for access control
   - Combining Design Modeling Languages with SecureUML
   - Semantics, i.e., what does it all mean,
   - Generation
   - Examples and experience
5. Model-driven security (Part II)
   - Continuation of above topics
6. Security patterns (design and implementation)
7. Implementation-level security
   - Buffer overflows
   - Input checking
   - Injection attacks
8. Testing
   - overview
   - model-based testing
   - testing security properties
9. Risk analysis and management 1 (project management)
   - "risk": assets, threats, vulnerabilities, risk
   - risk assessment: quantitative and qualitative
   - safeguards
   - generic risk analysis procedure
   - The OCTAVE approach
10. Risk analysis: IT baseline protection
    - Overview
    - Example
