| Abstract: | As cyberattacks grow increasingly sophisticated, the timely exchange of Cyber Threat Intelligence (CTI) has become essential to enhancing situational awareness and enabling proactive defense. Several challenges exist in CTI sharing, including the timely dissemination of threat information, the need for privacy and confidentiality, and the accessibility of data even in unstable network conditions. In addition to security and privacy, latency and throughput are critical performance metrics when selecting a suitable platform for CTI sharing. Substantial efforts have been devoted to developing effective solutions for CTI sharing. Several existing CTI sharing systems adopt either centralized or blockchain-based architectures. However, centralized models suffer from scalability bottlenecks and single points of failure, while the slow and limited transactions of blockchain make it unsuitable for real-time and reliable CTI sharing. To address these challenges, we propose a DDS-based framework that automates data sanitization, STIX-compliant structuring, and real-time dissemination of CTI. Our prototype evaluation demonstrates low latency, linear throughput scaling at configured send rates up to 125 messages per second, with 100% delivery success across all scenarios, while sustaining low CPU and memory overheads. The findings of this study highlight the unique ability of DDS to overcome the timeliness, security, automation, and reliability challenges of CTI sharing. [ABSTRACT FROM AUTHOR] |
