Identity Governance and Administration (IGA) is a policy-based framework within Identity and Access Management (IAM) that provides centralized visibility and control over user identities and access rights.
While standard IAM focuses on the technical execution of "Who can log in?", IGA focuses on the governance and auditing of "Should they have this access?" and "Can we prove it to an auditor?"
IGA is the primary defense against Privilege Creep and Orphaned Accounts caused by Data Sprawl and Shadow IT.
What Are The Core Components Of Identity Governance and Administration?
A modern IGA solution typically automates three critical lifecycle areas:
- Identity Lifecycle Management (JML): Automating the "Joiner, Mover, Leaver" process. This ensures a new hire gets "Birthright Access" on day one, and more importantly, that all access is instantly revoked the moment an employee leaves.
- Access Certification (Attestation): Periodic "campaigns" where managers must legally certify that their team members still require specific permissions. This prevents employees from accumulating unnecessary access as they change roles.
- Segregation of Duties (SoD): A compliance control that prevents a single user from having conflicting permissions (e.g., the person who requests a payment cannot be the same person who approves it).
- Entitlement Management: Providing a granular view of every specific "right" a user has across multi-cloud and SaaS environments, rather than just broad "Admin" or "User" labels.
Why Is IGA Essential For CISO Compliance?
For organizations facing CMMC, GDPR, or HIPAA audits, IGA is the "source of truth."
- Eliminating Orphaned Accounts: Attackers often target "Ghost Accounts", active logins for former employees. IGA identifies and deprovisions these automatically.
- Reducing the "Blast Radius": By enforcing Least Privilege (PoLP), IGA ensures that if a single account is compromised, the attacker only has access to a tiny fraction of the network.
- Audit Readiness: IGA provides a "push-button" audit trail, showing exactly who approved a specific permission and when, saving hundreds of hours during regulatory reviews.
- Governing Non-Human Identities (NHIs): AI agents and service accounts often outnumber human users. IGA provides the oversight needed to ensure these automated bots don't have excessive "standing" privileges.
How Does IGA Differ From Standard IAM?
It is a common mistake to use these terms interchangeably. Understanding the IGA vs. IAM distinction is critical for resource allocation.
| Feature | Identity and Access Management (IAM) | Identity Governance and Administration (IGA) |
|---|---|---|
| Primary Goal | Execution: Enabling access | Control: Governing and auditing access |
| Main Functions | SSO, MFA, Password Management | Lifecycle Management, Access Reviews, SoD |
| User Experience | Frictionless login/connectivity | Secure request and approval workflows |
| Compliance Role | Enforces security policies | Proves security policies are working |
FAQs: Identity Governance and Administration (IGA)
What is Privilege Creep in IGA?
Privilege Creep (or Entitlement Creep) occurs when an employee moves between departments and gains new permissions without losing their old ones. Over time, they become a "super-user" by accident, creating a massive insider risk.
How does IGA support a Zero Trust strategy?
Zero Trust requires "Continuous Verification." IGA provides the data needed for that verification by constantly reviewing whether a user’s current role still matches their assigned permissions.
Does IGA manage Shadow AI
Yes. Modern IGA tools can inventory Non-Human Identities and Shadow AI agents, ensuring that autonomous "bots" are bound by the same governance and Access Controls as human employees.
How does Theodosian bridge the gap between IGA and data security?
IGA tells you who should have access; Theodosian ensures that access is mathematically enforced at the file level.
- Cryptographic Attestation: We link your IGA approval workflows to our File-Centric Security. A user only gets the decryption key once the IGA system confirms their identity and role.
- Automated Revocation: If your IGA system triggers an "Offboarding" event, Theodosian can instantly revoke access to every protected file in that user's possession globally, regardless of where they stored it.
