Integrating CMDB Governance with Identity & Access Management for Enterprise Security

Abstract

In modern enterprises, Configuration Management Databases (CMDBs) and Identity & Access Management (IAM) are often managed separately, causing gaps in governance, visibility, and security. This study proposes a framework to integrate CMDB governance with IAM systems to enhance enterprise security, reduce risk, and improve compliance. We define governance principles for CMDB, align them with IAM lifecycle events, and simulate integration scenarios to evaluate effects on access anomalies, orphan accounts, and incident response time. Using statistical analysis on simulated data and scenario-based simulation, we show that integrated governance reduces access risk metrics by up to 35 % and improves mean time to detect unauthorized access by 28 %. The findings support adoption of such integration in real enterprises, subject to implementation challenges and tooling alignment.
