Game Theory for Privacy-Preserving Cybersecurity Information Exchange Framework

Analyzing the intricate dynamics of cyber threat information (CTI) sharing platforms promotes strategic data exchange, fortifying organizations with the collective strength needed to mitigate cyber threats effectively. This research aims to quantitatively assess the utility of joining a cyber threat intelligence platform. More specifically, this paper attempts to apply the principles of game theory to cyber threat intelligence platforms to uncover how the game develops over time and examine whether it is beneficial for an organization to join in the first place.
