Quantitative Assessment of Data Privacy and Access Control Effectiveness in SAP/ERP Analytics Systems

Abstract

Enterprise organizations increasingly rely on SAP and Enterprise Resource Planning (ERP) analytics systems to manage, process, and analyze large volumes of sensitive financial and operational data. Ensuring effective data privacy protection and access control within these integrated analytics environments has therefore become a critical requirement for maintaining enterprise information security and regulatory compliance. This study conducted a quantitative assessment of data privacy and access control effectiveness within SAP and ERP analytics systems operating in enterprise environments. The analysis was based on enterprise system records obtained from twelve SAP/ERP analytics platforms, comprising 18,750 authentication and authorization events extracted from audit logs, access control reports, and security monitoring systems. The study evaluated key security performance indicators including authorization accuracy, authentication response time, unauthorized access attempts, privilege escalation incidents, and audit compliance outcomes. Descriptive statistical analysis indicated that the evaluated enterprise systems achieved a mean authorization accuracy rate of 94.8%, demonstrating strong enforcement of role-based access control policies. The average authentication response time was 0.82 seconds, indicating stable system performance during user verification processes across the analyzed enterprise environments. Unauthorized access attempts occurred at a relatively low mean frequency of 29.7 incidents per evaluation cycle, while privilege escalation incidents averaged 7.0 events, suggesting that enterprise monitoring systems effectively restricted unauthorized access behavior. The analysis also revealed high levels of regulatory and policy adherence, with a mean audit compliance rate of 94.2% across the evaluated systems. Inferential statistical analysis further demonstrated statistically significant differences in authentication response time, unauthorized access attempts, and audit compliance performance across enterprise systems operating under varying levels of governance maturity and monitoring intensity. Systems equipped with stronger monitoring infrastructures and structured governance frameworks consistently achieved higher authorization accuracy rates and lower frequencies of access violations. Subgroup analysis additionally indicated that financial management and procurement modules recorded slightly higher audit exception frequencies due to the sensitivity of transactional enterprise data processed within these modules.
