IAM Governance

Identity systems have a bad habit of starting with a simple question: Who are you?

Then reality arrives.

• Who are you?
• What applications can you access?
• What groups are you in?
• Who approved those groups?
• Why do you have access to that application?
• Who gave you administrative privileges?How long have you had them?
• Does anyone still need them?
• What happens when you change jobs?
• What happens when you leave the company?
• What happens when an application is decommissioned?

And, perhaps most importantly:

Who can prove that the answers to those questions are correct?

That’s where Identity and Access Management Governance comes in.

IAM Governance is often treated as a feature of an Identity Governance and Administration system — something involving access reviews, certifications, workflows, and reports.

Those are important pieces.

But, governance is bigger than the product.

At its core, Identity Governance is about establishing who is allowed to decide what, under which rules, and how the organization knows those decisions are still correct.

Authentication Is Not Governance

We’ve spent years building systems that answer:

Who are you?

That’s authentication.

Then we built systems that answer:

What are you allowed to access?

That’s authorization.

Governance adds another set of questions:

Who decided you should have access?

• Why?
• Under what policy?
• For how long?
• Who is responsible for reviewing it?
• Can we prove that the decision was appropriate?

Those questions are fundamentally different.

Think about a normal application.

That tells us whether the user can get into the application.

It doesn’t necessarily tell us whether the user should have access.

Governance operates around that decision.

The Identity Lifecycle

The foundation of identity governance is the identity lifecycle.

• People join organizations.
• They change roles.
• They move between departments.
• They receive temporary responsibilities.
• They become managers.
• They lose responsibilities.
• Eventually, they leave.

The identity system needs to reflect those changes.

Conceptually:

This sounds obvious.

The problem is that most organizations don’t have a single system containing the complete truth about a person’s relationship with the organization.

You might have:

Governance is what helps connect these pieces into an accountable model.

Joiner, Mover, Leaver

One of the oldest concepts in Identity Governance is the Joiner-Mover-Leaver model.

Joiner

Someone joins the organization.

The organization needs to determine:

• What identity should be created?
• What baseline access should they receive?
• What applications do they need?
• What groups should they belong to?
• Who approves exceptions?

The important word is baseline.

You generally don’t want every new employee manually requesting every permission they need.

Instead, some access can be derived from organizational attributes.

For example:

That might result in access to:

The user doesn’t necessarily need to request each individual permission.

The policy determines the baseline.

Mover

This is where identity governance gets harder.

People change jobs.

Now, the user needs additional access.

But, what happens to the old access?

That’s the question organizations frequently get wrong.

A simplistic provisioning model says:

Governance requires asking:

Otherwise, access accumulates.

That’s permission creep.

Permission Creep

Permission creep is what happens when users accumulate access over time because old access isn’t removed.

Consider:

The employee may now have access to four applications.

But, perhaps they only need two.

Nobody intentionally designed the user to have excessive access.

It accumulated.

That’s one of the central problems IAM governance attempts to solve.

Leavers

The third category is the leaver.

Someone leaves the organization.

The desired outcome is fairly obvious:

The difficulty is that the identity may exist in dozens or hundreds of systems.

Disabling the account in the corporate directory doesn’t necessarily remove every application account.

That’s why Identity Lifecycle Governance often becomes an integration problem.

The Source of Truth Problem

Every organization eventually encounters the question, which system is authoritative?

For employee status, it might be HR.

For authentication, it might be an identity provider.

For application ownership, it might be a CMDB or application inventory.

For permissions, the application itself may be authoritative.

That means “the identity source of truth” is often not a single thing.

Instead, you have different authorities for different attributes.

Governance has to establish which source wins when those systems disagree.

Identity Governance Is About Decisions

This is the part that gets lost when governance is reduced to product features.

An IAM platform can execute a workflow.

• It can create an account.
• It can add a group.
• It can remove a permission.

But, governance is about the decision that caused those actions.

For example:

The provisioning system is performing an action.

The governance system is establishing why that action was allowed.

Who Owns the Access?

This creates another important concept:

Access ownership.

Someone needs to be responsible for determining whether a particular access permission is appropriate.

That might be:

• The user’s manager
• the application owner
• A data owner
• A security administrator
• A business process owner
• Some combination of these

For example:

The manager knows the employee.

The application owner knows the application.

The data owner knows the sensitivity of the data.

Governance is about putting those responsibilities in the right places.

Access Reviews

This is where many IAM governance products become visible to end users.

An access review asks someone with responsibility to confirm that access is still appropriate.

For example:

The review isn’t supposed to be ““Click Approve on everything.”

Unfortunately, that’s exactly what can happen when organizations create thousands of meaningless certifications.

If a manager receives:

Review 1,847 permissions

every quarter, the process becomes administrative theater.

The goal should be to make the decision understandable.

The reviewer should be able to understand why Alice has the access.

Birthright Access

Some access is expected based on a person’s role.

This is sometimes called birthright access.

For example:

The employee doesn’t need to submit a request for every basic service.

The organization defines the policy.

Governance still matters because birthright access should have an owner and a justification.

“Everyone gets it” is not the same thing as “nobody is responsible for it.”

Role-Based Access Control

IAM governance frequently uses Role-Based Access Control(RBAC).

Instead of assigning permissions directly to users:

we can introduce roles:

This gives governance a higher-level abstraction.

The organization can ask:

• Who should be an Accountant?

instead of:

• Should Alice have Permission A?
• Should Alice have Permission B?
• Should Alice have Permission C?

But, roles introduce their own governance problem.

Someone has to define what the role means.

Someone has to own it.

Someone has to review it.

And, someone has to notice when a role has accumulated permissions that no longer make sense.

Entitlements

IAM systems often use the word entitlement.

I never liked that word; listening to people talk about what they are entitled to annoys me (context matters).

An entitlement is essentially an access right that can be assigned or governed.

For example:

Governance can operate at different levels:

The exact terminology varies between products.

The underlying idea is the same: You need a manageable representation of access.

Separation of Duties

One of the more important governance concepts is Separation of Duties (SoD).

The basic idea is that certain combinations of privileges should not belong to the same person.

For example:

might represent a conflict.

Or:

might be prohibited.

The problem isn’t necessarily that either permission is dangerous by itself.

The problem is the combination.

Governance systems can identify these combinations and either prevent them or require an exception.

Policy Exceptions

Real organizations don’t fit perfectly into static rules.

Sometimes someone genuinely needs access that violates the normal policy.

That’s where exceptions come in.

For example:

The governance question isn’t “Can we make an exception?”

Of course, we can.

The question is, who approved it, why was it necessary, and when does it expire?

An exception without an expiration date has a tendency to become policy.

Privileged Access Is Different

Not all access has the same risk.

Reading a corporate directory is different from administering the identity provider.

Viewing a report is different from changing payroll.

Reading a database is different from having database administrator privileges.

Governance therefore needs some understanding of privilege.

A useful conceptual model is:

The higher the privilege, the stronger the governance controls generally need to be.

That can mean:

• Additional approval
• Shorter access duration
• Stronger authentication
• Privileged access management
• Additional monitoring
• More frequent reviews
• Tighter separation-of-duties rules

Temporary Access

Permanent access is easy to understand.

Temporary access is often safer.

Instead of:

you can have:

This is especially useful for privileged operations.

The important governance property is that the access has a defined lifecycle.

That reduces the amount of permanent privilege floating around the organization.

Identity Governance Across Applications

The real problem gets larger as the organization grows.

A user might have identities in:

Some systems may support modern identity protocols.

• Others may have APIs.
• Others may only have SCIM.
• Others may have proprietary provisioning interfaces.

And, some will inevitably have username + password hidden somewhere in a server room that everyone hoped had been retired three years ago.

Governance has to operate across this mess.

That’s why identity governance and administration frequently intersects with:

• IAM
• IGA
• PAM
• Directory services
• SSO
• SCIM
• HR systems
• Application inventories
• Cloud IAM
• Security monitoring

SCIM Helps, But SCIM Isn’t Governance

This distinction is particularly important.

System for Cross-Domain Identity Management (SCIM) can provide standardized provisioning and lifecycle management between systems.

For example:

The identity system can create, update, and deactivate accounts.

That’s useful.

But, SCIM doesn’t decide whether the user should have access.

Governance makes that decision.

SCIM is the mechanism.

Governance is the policy and decision-making layer.

Governance for Service Identities

There is another identity problem that becomes increasingly important as organizations automate everything.

Not every identity represents a human.

We, also, have:

• Service Accounts
• Workloads
• Applications
• APIs
• Bots
• Automation
• Agents
• Machine Identities

The lifecycle problem still exists.

• Who owns a service account?
• Why does it exist?
• What application uses it?
• What permissions does it have?
• When was it last used?
• What happens when the application is retired?

Those are governance questions.

Machine Identity Governance

Machine identities can actually be harder than human identities.

Humans generally have an HR record.

A service account might not.

You might find:

svc-backup
svc-api
svc-integration
svc-old
svc-old2
svc-new

Nobody knows who owns svc-old2.

It still has access to a database.

It still has a credential.

And, it hasn’t been used in 14 months.

That’s an Identity Governance problem.

The organization needs an inventory.

Without that information, you aren’t governing the identity.

You’re just accumulating accounts.

Identity Governance and Zero Trust

Zero Trust is often summarized as: Never trust, always verify.

But verification isn’t enough.

An organization also needs to know what should be trusted in the first place.

Consider:

Governance sits above and around those decisions.

It establishes things like:

• Which identities exist?
• Which roles exist?
• Which permissions belong to those roles?
• Who owns them?
• Which combinations are prohibited?
• How long should access last?
• Who can approve exceptions?

Zero Trust needs trustworthy identity and authorization decisions.

Governance helps establish the policies behind those decisions.

Governance Is Also About Evidence

Eventually, someone will ask**, “Why does this person have access?”**

You need an answer.

Not, “The application says they’re an administrator.”

That’s the current state.

The governance question is “Why were they granted administrator access?”

You may need to establish:

That creates an audit trail.

The organization can demonstrate not only what access exists, but why it exists.

Governance Is a Feedback Loop

A mature identity governance system isn’t just:

It’s a continuous feedback loop.

People change.

Applications change.

Organizations change.

Permissions change.

Therefore, the access model has to change with them.

The Bigger Problem: Governance at Scale

This is where IAM Governance becomes difficult.

Suppose you have:

50,000 Employees
5,000 Applications
10,000 Groups
100,000 Entitlements
Millions of Access Relationships

You can’t manage that effectively with spreadsheets and quarterly emails.

You need automation.

But, automation creates another problem.

If you automate a bad policy, you simply make the bad policy operate faster.

Governance therefore needs both Automation and Policy.

Neither is sufficient by itself.

The Real Question

Identity governance isn’t ultimately about having a dashboard showing green check marks.

It’s about answering a set of fundamental questions:

Those questions apply to humans.

They apply to administrators.

They apply to service accounts.

They apply to workloads.

They increasingly apply to applications and automated agents.

IAM Governance Is the Control Plane for Identity

It’s useful to think about the relationship this way:

• IAM systems enforce identity and access.
• PAM systems control privileged access.
• Applications enforce their own authorization.
• SCIM can move identity and group information between systems.
• Authentication systems establish identity.

But, governance sits above all of them and asks, should this access exist, and can we prove why?

The Identity Governance Mindset

The biggest shift is moving from:

“Can this user access the system?”

to:

“Should this user have this access, under this policy, for this amount of time, with this level of privilege — and who is accountable for that decision?”

That is a much harder question.

It is also the question that matters when something goes wrong.

Because, after an incident, nobody is particularly interested in hearing that he directory said the user was in the group.

The next question is “Why was the user in the group?”

And, then, “Who approved that?”

And, then, “Why was it still there six months later?”

That’s identity governance.

It isn’t simply about managing identities.

It is about governing the decisions that determine what those identities are allowed to do.
