Abstract

In the context of the digital age, the concealment of cyber attacks continues to increase, posing a serious threat to information security. This article focuses on the research of network attack concealment and its anti detection technology, aiming to enhance the network security defense capability. The introduction section elaborates on the background and significance of the research, pointing out that with the widespread application of network technology, attack methods are becoming increasingly diverse and covert, and emphasizing the necessity of conducting this study. By analyzing the current research status at home and abroad, the research gaps and development directions have been identified. The research aims to explore effective anti detection techniques to cope with complex and ever-changing network attacks. Chapter 2 provides a detailed definition of covert attacks and categorizes them, while analyzing techniques such as exploiting system vulnerabilities and encryption obfuscation. Through case analysis, we have further understood the implementation process and methods of covert attacks. Chapter 3 explores the principles of anti detection technology, including behavior analysis, log analysis, and methods based on artificial intelligence. Especially in the field of artificial intelligence, the application of reinforcement learning provides new ideas for optimizing defense strategies. Chapter 4 discusses the challenges faced by anti detection technology, such as the evolution of covert technology, conflicts in big data privacy protection, and regulatory issues in cross-border cyberspace, and proposes corresponding countermeasures. The conclusion section summarizes the research results, points out the limitations of the study and future research directions, and provides reference for researchers and practitioners in the field of network security.
