Security Issues in Cyber Threat Intelligence Exchange: A Review

Abstract

The cost and time required by individual organizations to build an effective cyber defence can become overwhelming with the growing number of cyber attacks. Hence, the introduction of platforms that encourage collaborative effort in the fight against cyber attacks is considered advantageous. However, the acceptability and efficiency of the CTI exchange platforms is massively challenged by lack of trust caused by security issues encountered in such communities. This review examines the security and participation cost issues revolving around the willingness of participants to either join or actively participate in CTI exchange communities and proposed solutions to the security issues from the research perspective.
