The Internet has a significant impact on people's daily lives and work. Recent studies claim that Artificial Intelligence (AI) has resulted in advances of many scientific and tech- nological fields, that is, AI-based medicine, AI-based trans- portation, and AI-based finance. The era of AI is upon us. As one of the biggest concerns, security is of significance to the development of a sustainable, resilient, and prosperous Internet ecosystem. However, cybersecurity still faces many challenging issues such as intrusion detection, privacy pro- tection, proactive defense, anomalous behaviors, advanced threat detection, and so on. In addition, many threat variations emerge and spread continuously. AI-assisted self-adaptable approaches are expected to deal with these security issues. A joint consideration of the interweaving nature between AI and cybersecurity is a key factor for driving future secure Internet.
