Abstract: Distributed Big Data systems form the backbone of modern analytics-driven organizations, enabling scalable storage, fast computation, and real-time processing. However, their distributed and heterogeneous nature introduces complex security challenges that differ significantly from traditional centralized systems. This extended essay examines major security concerns such as data confidentiality, integrity, access control, insider threats, network-based attacks, and infrastructural vulnerabilities. It also discusses why these issues are amplified in distributed environments and presents a comprehensive overview of modern mitigation strategies. This expanded version provides deeper insights, additional context, and elaborated arguments to meet academic publication standards and maintain a 1000-word requirement.
