Cybercrime has become one of the fundamental challenges of human societies in the present era, which has become more complex with the increasing expansion of information and communication technology. These crimes, which include illegal activities in cyberspace, from transnational organized crimes to individual fraud and defamation, seriously threaten individual, social and even national security. In this study, with an analytical-descriptive approach, a comprehensive study of the strategies for preventing and combating cybercrimes in the Iranian criminal system is conducted. First, the key concepts related to cybercrimes and their common types are explained, and then the existing legal framework for combating these crimes is evaluated. Next, preventive strategies at various levels, including technical, legal, cultural, and educational, are discussed and examined, and their effectiveness in reducing the occurrence of cybercrimes is explained. Also, challenges and obstacles in the path of effective implementation of these solutions, including legal gaps, weak technical infrastructure, lack of specialized training, and international cooperation, are identified and analyzed. Finally, by providing practical suggestions for amending and supplementing laws, strengthening technical and judicial infrastructure, promoting citizens' legal culture, and developing regional and international cooperation, an effective step will be taken towards creating a safe and sustainable environment in cyberspace.
