CSC8201 : The Challenge of Dependable Systems

Semesters
Semester 1 Credit Value: 10
ECTS Credits: 5.0

Aims

To introduce the concepts, principles and ethics of dependable systems, including: the notions of security, safety and reliability, the flaws that undermine dependability, the analyses that expose weaknesses, the techniques that can impart resilience, and the arguments that engender trust in a system.

Outline Of Syllabus

1. Components, systems, interfaces, environments, and ethical issues:
trusted vs. trustworthy,
success vs. failure,
safe and secure and reliable.
2. Flaws and weaknesses:
physical deterioration and design inadequacy,
accidental misuse and malicious attack.
3. Concepts and terminology:
faults, errors, failures,
tolerance, resilience, reconfiguration.
4. Hazards and accidents:
safety analysis and integrity levels,
safety culture, management and life-cycle,
risk management and ALARP.
5. Dependability cases:
professional and legal aspects: the safety case and regulation,
arguments, evidence and goal structured notation (GSN),
fault models and hypotheses.

Teaching Methods

Please note that module leaders are reviewing the module teaching and assessment methods for Semester 2 modules, in light of the Covid-19 restrictions. There may also be a few further changes to Semester 1 modules. Final information will be available by the end of August 2020 in for Semester 1 modules and the end of October 2020 for Semester 2 modules.

Teaching Rationale And Relationship

Lectures will be used to introduce the learning material and for demonstrating the key concepts by example. Students are expected to follow-up lectures within a few days by re-reading and annotating lecture notes to aid deep learning.

This is a very practical subject, and therefore students are expected to read outside of taught materials (e.g., published papers) from the perspective of how dependability failures can occur and how they are also avoided through careful design in real-world systems.

Learning materials are supported by worked examples provided as class exercises. Students are expected to spend time on coursework outside scheduled activities.

Students aiming for Distinction-level marks are expected to widen their knowledge beyond the content of lecture notes through background reading.

Students should set aside sufficient time to read and understand the suggested literature before setting down to do the assessments.

Assessment Rationale And Relationship

The project work assessments assess knowledge of theoretical, including ethical, underpinnings and practical skills on selected, realistic and open-ended problems. They also seek to expose the students to the link between theory and practice and the importance of conceptual underpinnings in building dependable systems.
