Overview: Identity Governance and Administration (IGA)

Quick Definition

Identity Governance and Administration is a cybersecurity framework that manages digital identities and their access rights throughout an organization. IGA combines identity management technologies with governance policies to ensure that users have appropriate access to systems and data based on their roles, while maintaining security and compliance requirements.

The governance component focuses on establishing policies, procedures, and controls for managing identities and access rights. This includes defining who should have access to what resources, under what circumstances, and for how long. Administration involves the technical implementation and day-to-day management of these policies, including user provisioning, de-provisioning, access reviews, and role management.

Key IGA capabilities include automated user lifecycle management, role-based access control (RBAC), access certification and reviews, segregation of duties enforcement, and compliance reporting. These tools help organizations reduce security risks by ensuring users don't accumulate excessive privileges over time—a common problem known as "privilege creep."

IGA solutions are particularly important for large enterprises with complex IT environments, regulatory compliance requirements, and high employee turnover. By automating identity management processes and providing visibility into access rights, IGA helps organizations maintain the principle of least privilege while reducing administrative overhead and improving audit readiness.
