The book aims to build a bridge between criminological perspective and cybercrime-related disciplines; I hope that new book can provide potential benefits to researchers and practitioners of intersecting disciplines to minimize cybercrime issues via an application of criminological science. Cybercrime issues can potentially impact anyone in the world anywhere in the world. Nations are expanding their technological capability to monitor cybercrime issues. This naturally requires international cooperation and constant efforts from government agencies, private sectors, and educational institutes. The book demonstrates empirical assessment of cybercrime victimizations via the application of Routine Activity Theory (RAT). The concept of three main risk factors, i) Motivated Offenders, ii) Suitable Target, and iii) Capable Guardianship, which contribute to computer crime/cybercrime, was used to assess the new theoretical model advanced in my research by providing an overall picture of the relationship among the causal factors and computer-crime/ cybercrime victimization.
