Cybercrime threatens individual security through unauthorized access to personal assets. It involves identity theft, data breaches (information resource theft), account hijacking, and the distribution of viruses embedded in files, websites, and critical codes. It may also encompass acts of defamation, slander, and reputational harm. Similarly, industrial espionage and the hostage-taking of critical information resources have become increasingly prevalent. These phenomena have caused public concern due to the erosion of privacy and the looming threat of asset loss and intellectual property theft. Personal data protection has become a crucial preventive measure in response to the growing threat to personal data security. This study used a normative juridical method to systematically and normatively explore and analyze the legal aspects of specific issues or topics. The method emphasizes an in-depth examination of legal norms derived from various sources, such as legislation, court decisions, and legal literature. Therefore, this study concludes that constitutional law is essential to solve cybercrime by regulating state authority, protecting constitutional rights, formulating legal frameworks, coordinating interagency, and safeguarding cyber sovereignty. Constitutional Law ensures that responses to cybercrime are carried out under the principles of the rule of law and democracy, while simultaneously protecting national interests and citizens’ rights.
