Advanced Role-Based Access Control Models for Enhancing Database Security in Big Data Environments

Abstract

In the era of big data, securing databases against unauthorized access and breaches has become increasingly complex. Traditional Role-Based Access Control (RBAC) models may not suffice in addressing the unique challenges posed by big data environments. This paper explores advanced RBAC models designed to enhance database security in such contexts. We propose novel RBAC frameworks and evaluate their effectiveness in protecting sensitive data while ensuring operational efficiency.
