"The Shy Investor: CryptoCurrencies" is a fictional case written from the point of view of an investor carrying out investment risk analysis. The protagonist is a reasonably wealthy woman in Russia who wishes to diversify her investment portfolio. The case uses a fictitious cryptocurrency called URLBoyzCoyn issued by or on behalf of an equally unreal thrash heavy metal band called the URLBoyz. The overall theme is the assessment of risk and the factors to consider before investing in cryptocurrency. The case contrasts the high returns that can be and have been made by early speculators in cryptocurrencies generally. With the risks that later entrants to the market may have to shoulder.

300cubits is a blockchain application that aims to solve the no-show problem in the cargo shipping industry. Its founders, Johnson Leung and Jonathan Lee, are two HKUST alumni with experience in banking and shipping. They have identified a pain point, in the cargo shipping industry which does not require a pre-shipping cash deposit, results in no-show and cargo roll-over problems. They developed a new Ethereum based cryptocurrency, TEU, to serve as such collateral. They then conducted an initial coin offering (ICO) pre-sale in September 2017, and an official ICO in April 2018. However, the ICO failed to raise a lot of capital. However, the uptake of TEU tokens was very slow in the industry. They are now pondering the next steps forward.

In this series of case studies, students learn to identify, assess, and control the risks of distributed denial of service (DDoS) attacks in a real-world situation. PopVote was the electronic voting system used by the Public Opinion Programme (POP) at the University of Hong Kong. This case consists of cases A, B, and C. Case A gives the background on POP and PopVote. It describes the development history of PopVote, including past voting events, past cyber-attacks, and the evolution of its IT security infrastructure. Students are asked how to identify and assess potential security risks and how to prepare PopVote for an upcoming high-visibility voting event.

In this series of case studies, students learn to identify, assess, and control the risks of distributed denial of service (DDoS) attacks in a real-world situation. PopVote was the electronic voting system used by the Public Opinion Programme (POP) at the University of Hong Kong. This case study consists of cases A, B, and C. Case B sets the scene for risk control in information security management. To improve cloud-based security, POP outsourced the system security to Amazon Web Services (AWS), CloudFlare, and UDomain. During the mock and preregistration period of the voting event, the scale of DDoS attacks forced AWS and UDomain to make an unusual move and withdraw their services. CloudFlare also warned that it might suspend its service if there was another wave of cyber-attacks. The POP team had to decide immediately what they should do to control the risks.
