Data Security: A Systematic Literature Review and Critical Analysis

This paper systematically reviews the existing literature on data security. This study aims to identify current research directions, identify the main challenges facing data security, and suggest future research directions in this field. The research method is a structured approach to searching and selecting relevant papers based on predefined inclusion and exclusion criteria. The selected articles were then analyzed to identify common themes, methodologies, and main findings. The study reveals vital research directions, such as cloud data security, IoT data security, data encryption, data security attack analysis, and data security policy. Challenges identified include scalability in data security, privacy, and regulatory compliance, increasingly complex attack threats, and a lack of awareness of the importance of data security. Based on these findings, the study also recommends future research, including developing innovative security technologies, data security awareness and training, and research into data security's ethical and legal aspects.
