What are the trend and core knowledge of information security? A citation and co-citation analysis

Information technology brings business success opportunities, but also causes potential safety hazards to orga-nizations. In response to the increasing academia and industry concerns regarding information security (ISec), this study systematically explored extant ISec research and identified eight core knowledge groups, including (1) intrusion detection, (2) privacy protection, (3) secure machine learning, (4) cryptosystem, (5) data service se-curity, (6) malware analysis, (7) security decision-making, and (8) security management. The detection of research hotspots shows that data service security and risk management garner the most current research attention. Furthermore, we establish a comprehensive ISec framework to help systematically understand and achieve ISec.

Automated summary

Information technology presents both business success opportunities and potential safety hazards to organizations. This study systematically explores information security research and identifies eight core knowledge groups, including intrusion detection, privacy protection, secure machine learning, cryptosystem, data service security, malware analysis, security decision-making, and security management. The detection of research hotspots reveals that data service security and risk management receive the most research attention. Additionally, a comprehensive information security framework is established to facilitate a systematic understanding and achievement of information security.
