Cloud Identity Debt: Quantifying and Managing the Risk of Over-Provisioned Access in Enterprise Cloud Transformation

Abstract

In the midst of rapid enterprise cloud adoption, a subtle yet significant security vulnerability often goes unnoticed: cloud identity debt. Think of it as the digital equivalent of clutter, where excessive, unused, or orphaned access rights accumulate in dynamic cloud environments. It’s a growing security risk that goes against the fundamental principle of least privilege, essentially widening the door for potential breaches. Like technical debt in software development, identity debt represents deferred governance costs that only grow over time, increasing the likelihood of a security incident. This article introduces a robust framework to understand, measure, and fix this critical security issue using the Identity Debt Quotient (IDQ), a new metric that quantifies over-provisioned access in cloud environments. This mismatch often leads to "permission bloat," a surge in service accounts, and significant gaps in governance. To truly address this, organizations need sophisticated strategies. Researchers talking about combining automated entitlement reviews, smart policy-based provisioning, and integrated analytics with strong governance structures. By putting these measurement and remediation strategies into practice, organizations can significantly shrink their attack surface and optimize their governance resources, leading to sustainable identity debt management in complex cloud environments.
