Identity Governance and Administration (IGA) in Regulated Industries

Identity governance has moved from a back-office housekeeping task to a board-level obligation for Australian enterprises in banking, insurance, health and government. Regulators now expect organisations to prove — not just assert — that the right people have the right access to the right systems, and that every entitlement can be traced, justified and revoked. For regulated industries, a mature identity governance and administration (IGA) programme is the difference between passing an audit cleanly and scrambling to explain why a departed contractor still had access to a production database six months later.

This guide explains what IGA actually delivers, why regulated sectors in Australia and across APAC face particular pressure, and how to build a programme that satisfies auditors without grinding the business to a halt.

What identity governance and administration actually covers

IGA is the discipline of managing digital identities and their access rights across their entire lifecycle — from the day someone joins to the day they leave, and every role change in between. It sits above the day-to-day mechanics of authentication and single sign-on, answering a harder set of questions:

• Who has access to what, and can you produce that answer on demand?
• Should they still have it? Access granted for a project two years ago rarely gets cleaned up on its own.
• Who approved it, and is that approval recorded in a way an auditor will accept?
• Are risky combinations blocked? Separation-of-duties conflicts — such as one person both raising and approving a payment — need to be detected before they become a fraud finding.

A working IGA capability typically combines automated joiner-mover-leaver provisioning, periodic access certifications (or “recertifications”), role-based access models, segregation-of-duties controls, and a complete audit trail. Done well, it reduces the standing access that attackers exploit and shrinks the manual review burden that quietly consumes IT and risk teams.

IGA vs IAM vs PAM — where the lines sit

These acronyms overlap and get used loosely. Identity and access management (IAM) is the broad umbrella covering authentication and access. Privileged access management (PAM) focuses specifically on high-risk administrative accounts. IGA is the governance layer that decides and evidences who should have access in the first place. Most regulated enterprises need all three working together. If you’re untangling the first two, our explainer on IAM vs PAM is a useful companion read.

Why regulated industries in Australia feel the pressure

Regulated sectors carry obligations that make weak identity governance genuinely expensive. In Australian financial services, APRA’s CPS 234 requires regulated entities to maintain information security capabilities commensurate with the threats they face — and access management is a recurring theme in the control expectations and in post-incident reviews. Health and government bodies handling sensitive personal information sit under the Privacy Act and, increasingly, sector-specific data-handling rules. Across APAC, comparable regimes apply: Singapore’s MAS Technology Risk Management guidelines and New Zealand’s evolving privacy expectations push in the same direction.

The common thread is evidence. It is no longer enough to have a policy that says access is reviewed. Auditors want to see the review happened, on a defined cadence, with named approvers and documented outcomes. Organisations that manage certifications in spreadsheets typically discover — usually mid-audit — that the evidence is incomplete, stale, or impossible to reconcile against the live directory.

The cost of “access sprawl”

In large enterprises, entitlements accumulate faster than anyone removes them. People change roles and keep old access “just in case”. Contractors onboard quickly and offboard slowly. Service accounts multiply. The result is access sprawl: a growing population of standing privileges that expands the attack surface and makes every certification cycle more painful. Regulated industries feel this acutely because the systems in question — core banking, policy administration, patient records — are exactly the ones regulators scrutinise.

Building an IGA programme that auditors trust

A durable identity governance capability in a regulated Australian enterprise usually comes together in stages rather than a single big-bang rollout.

1. Establish an authoritative source of identity

Governance is only as good as the data underneath it. The HR system (for employees) and a contractor register (for non-employees) should drive identity lifecycle events. When a leaver is marked terminated in HR, downstream access should be revoked automatically — not left to a manual ticket that may never be raised.

2. Automate joiner-mover-leaver provisioning

Automated provisioning removes the two biggest sources of audit findings: access that is granted too broadly on day one, and access that lingers after departure or role change. Birthright access tied to role, with everything beyond that requested and approved, gives you both speed and control.

3. Model access with roles — but stay pragmatic

Role-based access control makes certifications tractable, because reviewers approve a coherent role rather than hundreds of individual entitlements. The trap is over-engineering the role model until it becomes unmaintainable. Start with high-value, high-population roles, and accept that some access will always be handled as exceptions.

4. Run risk-based access certifications

Certifying everything on the same cycle wastes reviewer attention on low-risk access and rushes the review of dangerous access. Prioritise privileged accounts, access to regulated data, and separation-of-duties-sensitive entitlements for more frequent, more careful review. Rubber-stamping is the enemy — a certification that approves 100% of access in seconds is a finding waiting to happen.

5. Capture the evidence automatically

Every grant, approval, certification decision and revocation should be logged in a form you can hand to an auditor without a week of preparation. This is where a purpose-built IGA platform earns its keep over manual processes.

Common pitfalls to avoid

• Treating IGA as a tooling project. The technology is the easy part. The hard part is defining roles, owners and approval workflows with the business — which is where most programmes stall.
• Boiling the ocean. Attempting to onboard every application at once usually collapses under its own weight. Sequence by risk and regulatory exposure.
• Ignoring non-human identities. Service accounts, API keys and automation credentials often outnumber human users and are frequently the least governed.
• Certification fatigue. If reviewers are drowning, they rubber-stamp. Reduce the volume with better role models and risk-based scoping so the reviews that matter get real attention.

Where Delivery Centric fits

Delivery Centric helps Australian and APAC enterprises design and deliver identity governance programmes that stand up to regulatory scrutiny — from establishing authoritative identity sources and automating the joiner-mover-leaver lifecycle, to building role models and risk-based certification processes that satisfy APRA, MAS and privacy obligations without exhausting the business. Our consultants work across banking, insurance, health and government, and pair governance design with the wider identity and cyber security services that regulated organisations depend on. For teams weighing regulatory readiness specifically, our APRA CPS 234 compliance checklist is a practical starting point.
