Introduction: Refresh on fundamental networking principles and devices and distributed systems, the context within which cybersecurity (or lack thereof) can be present. Network structure and ways of communication. History of cybersecurity: important attacks and consequences. Related history (e.g. the important role of cryptography and cryptanalysis in World War II, etc.) Current importance of cybersecurity, given the connectedness of most of our daily lives. Analysis of critical infrastructures and the position of critical information infrastructures within these – importance of the protection of such systems for the smooth operation of essential services in all areas of life. The network as a route for cyberattacks, how the network can be protected, vulnerabilities, threats. Asset protection (including data) as a valuable business operation and its contribution to business survivability. Main principles of cybersecurity – confidentiality, integrity, availability and combinations thereof, resulting in other important cybersecurity concepts and services – accountability, non-repudiation, authenticity, resilience, business continuity and disaster recovery, audit, cybercrime, data / system / network forensics, cyberdefence. Introduction to the phases of cybersecurity – Identify, Protect, Detect, Respond, Recover. Applicable cybersecurity and IT law Software licensing, Data privacy and security, Electronic signatures, Legal and regulatory risks, cyberattacks, digital forensics, liability issues, trust. Introduction to ISO/IEC 27001 Information security management. Introduction to other courses in this MSc (to aid selection of the elective courses). Introduction to specific cybersecurity topics – database security, secure software development, malware analysis, etc. Business case study and lecture: Lecture by invited experts from the cybersecurity industry. Discussion normally focuses on usual network attacks and methods for protection.
