This study employs the PRISMA methodology to conduct a comprehensive review, aiming to examine the current state of information security in an information society. The study specifically focuses on the methods used to access protected information. The review consolidates findings from multiple scholarly sources, emphasizing common dangers, measures for mitigation, and optimal approaches to protecting digital information. The evaluation procedure involved conducting an extensive search across various academic databases such as Science Direct, Scopus, Web of Sciences, PubMed, and DOAJ, where a total of 105 documents were found, comprising 85 papers and 20 reports. The findings highlight the complex and diverse aspects of information security, emphasizing the need for a comprehensive approach that incorporates technological, organizational, and human components. The analysis demonstrates that although there have been notable advancements in the creation of advanced security measures, there are still obstacles to overcome, such as the emergence of new threats and the necessity for ongoing adjustment. The paper also highlights deficiencies in existing research, proposing areas for future exploration to strengthen the security position of information systems in a progressively networked world. This systematic review enhances existing knowledge by presenting a comprehensive overview of the current state of information security. It provides valuable insights for researchers, practitioners, and policymakers who are committed to safeguarding sensitive information in a society driven by information.
