Cybersecurity Risk Detection and Assessment of Availability and Confidentiality Attacks in Stock Markets

The computerization of stock markets has greatly improved trading efficiency but, at the same time, brought exposures to cyberattacks. This paper discusses two most important categories of cyberattacks in stock markets: Availability Attacks and Confidentiality Attacks. Whereas availability attacks cause an impairment in the normal functioning of markets, confidentiality attacks compromise sensitive financial information. This research assesses the trend of these attacks through mathematical modeling and experimental verification with AI-based detection methods. A model for risk assessment is envisioned in order to measure and prioritize threats by their severity to effectively develop mitigation strategies. The results ensure investor confidence and business resilience by identifying the strengths and weaknesses of different detection methods.
