Purpose: This article examines the impact of the science and technology development and artificial intelligence on cyber threats in the era of the 4th industrial revolution and consideration of national-level defense response to the cyber threats. Method: The theoretical approach referred to monographs and papers published in academic journals, and technical and current data were studied through the Internet and literature research. Results: The development of artificial intelligence has provided efficiency, speed, and convenience of mission performance in cyberspace, but threats from unspecified forces in cyberspace are becoming more covert, advanced, and intelligent. Impairment of mission performance and damage to property has emerged as a national crisis. It has become a new security issue that must be dealt at the national security level. In response to cyber threats, the development tasks include nurturing cybersecurity experts, developing artificial intelligence-based security control management highlighting hacking and malicious code breaches based on artificial intelligence, and improving cybersecurity awareness. Conclusion: Defense, which plays a pivotal role in national security, is expected to serve as an opportunity to strengthen cybersecurity capabilities as a game-changer to respond to cyber threats on the battlefield along with the 4th industrial revolution and the innovative development of artificial intelligence.
