In the twenty-first century, the prevention of cyber attacks on critical infrastructure, key assets, and public/private sector enterprises will become a more important element of national and international security. This paper examines the extant literature published on the increasing need for a more robust, comprehensive and proactive approach to cybersecurity. Specifically, the paper explores the contemporary cyberspace environment and the current cyber threat landscape. The paper recommends the application of cyber threat intelligence (CTI) complemented by predictive analytics as an effective method for countering cyber attacks. The purpose of the paper is to advance the knowledge in this critical area, to increase the understanding of available methods for proactive detection of network security intrusions, and to highlight an emerging innovative approach to cyber threat intelligence.
