**Stages** & **Topic Words** \\ \hline Stage 8 & 8\_1 (Role of Authentication in DDoS Defense); 8\_2 (The Role of Intrusion Detection Systems); 8\_3 (Network Traffic \& Cybercrime); 8\_4 (Validated Techniques for Intrusion); 8\_5 (Key Identification Techniques); 8\_6 (Identification of Vulnerabilities); 8\_7 (Detection of Malware); \\ \hline Stage 9 & 9\_1 (Cyber Defense Strategies); 9\_2 (Network Traffic Analysis in Intrusion Detection); 9\_3 (Role of Cybercrime); 9\_4 (Cyberattack Identification); 9\_5 (Firewall Configuration and Secure Network Access Controls); 9\_6 (Private Data Capture and Utilization Precautions); 9\_7 (Application of Encryption and Cryptographic Policies in Ransomware and Blockchain Technology); \\ \hline Stage10 & 10\_1 (Optimization of Intrusion Detection Technology);This study conducts training with the LDA model to obtain the scientific topics and technical topics in the field of cybersecurity from 2005 to 2024. These topics are highly focused on the field of cybersecurity, reflecting their close association. Meanwhile, these topics are based on the two major levels of science and technology, presenting significant differences and diversity. Conducting an in-depth analysis of these two types of topics can not only trace the development process of science and technology in the field of cybersecurity and organize their key technological nodes in different periods, but also allow us to gain insights into the dynamic interactive relationship between science and technology in the development process from a topic perspective, providing a reference for deeply understanding the correlation between science and technology in the field of cybersecurity.
