Choosing the Right Administrative Environment

Throughout this series we’ve explored what a Privileged Access Workstation is, why it matters and the different ways it can be implemented.

We’ve seen that dedicated physical PAWs continue to provide the highest level of administrative assurance, while virtual PAWs offer a practical alternative for many organisations.

The obvious question is now:

Which approach should you choose?

The answer isn’t found in Microsoft documentation, industry best practices or a compliance framework.

It’s found by understanding your organisation’s risk, operational requirements and the level of trust placed in your privileged identities.

There Is No Universal Answer

One of the biggest mistakes organisations make is looking for a single answer that applies to every administrator.

Should every administrator have a dedicated physical PAW?

Probably not.

Should every administrator use a virtual PAW?

Not necessarily.

Should every administrator simply use their everyday corporate laptop?

Almost certainly not.

Every privileged identity carries a different level of organisational impact.

Every organisation operates under different constraints.

Every security team has a different appetite for risk.

The objective isn’t consistency for the sake of consistency.

The objective is providing the right level of assurance for each privileged identity.

Start With Risk, Not Technology

Technology should never drive security architecture.

Risk should.

Before selecting an administrative environment, ask questions such as:

  • What can this identity change?
  • Can it modify authentication methods?
  • Can it assign privileged roles?
  • Can it change Conditional Access policies?
  • Can it disable security controls?
  • Can it access sensitive information?
  • Would the compromise of this identity have a significant business impact?

The answers are far more important than whether you’re considering Windows 365, Azure Virtual Desktop or dedicated hardware.

Operational Reality Matters

Security is rarely the only consideration.

Architecture is about balancing competing requirements.

You may need to consider:

  • Budget constraints
  • Remote administrators
  • International teams
  • Contractors
  • Third-party support providers
  • Temporary privileged access
  • Shift workers
  • Disaster recovery
  • Device logistics
  • Procurement

A dedicated physical PAW may provide the highest level of assurance, but it may also introduce operational challenges that aren’t appropriate for every administrative role.

Equally, a virtual PAW may provide an excellent balance between assurance, flexibility and cost.

The right answer depends on your organisation.

Matching the Environment to the Identity

Rather than asking which technology is best, ask which environment is appropriate for the identity.

For example:

Highest Assurance

Examples include:

  • Global Administrator
  • Privileged Role Administrator
  • Security Administrator

These identities often justify the highest level of workstation assurance.

A dedicated physical PAW is frequently the preferred option, although some organisations may determine that a dedicated virtual PAW provides an acceptable balance.

High Assurance

Examples include:

  • Exchange Administrator
  • SharePoint Administrator
  • Teams Administrator
  • Intune Administrator
  • Conditional Access Administrator

These identities administer business-critical services but may not require the same level of assurance as the identities responsible for protecting the Microsoft Entra control plane.

Dedicated virtual PAWs often provide an excellent solution.

Operational Administration

Examples include:

  • User Administrator
  • Helpdesk Administrator
  • Password Administrator

These roles still perform privileged operations but typically present a lower organisational impact if compromised.

A well-managed and appropriately hardened corporate device may provide an acceptable level of assurance.

The important point is that these decisions should be made consciously and documented as part of the organisation’s security strategy.

Compliance May Influence the Decision

For some organisations, the decision has already been made.

Industries such as defence, government, financial services and critical national infrastructure may have regulatory or contractual requirements that influence how privileged administration is performed.

In these environments, dedicated physical PAWs may be mandatory for certain administrative roles.

Technology should support compliance requirements, not attempt to replace them.

Avoid One-Size-Fits-All Security

It’s easy to create security policies that apply equally to everyone.

It’s much harder to create policies that reflect actual business risk.

Giving every administrator a dedicated physical PAW may increase assurance, but it also increases cost, operational complexity and management overhead.

Giving every administrator a standard corporate laptop may reduce costs, but it may also expose your highest assurance identities to unnecessary risk.

Neither extreme is ideal.

Good security architecture finds the right balance.

A Practical Decision Matrix

When deciding on an administrative environment, consider the following questions:

  • How critical is the identity?
  • What is the business impact if it’s compromised?
  • Does the role administer authentication or security controls?
  • Are there regulatory requirements?
  • Is the administrator permanent or temporary?
  • Does the role require mobility?
  • What operational constraints exist?
  • What level of risk is the organisation prepared to accept?

Answering these questions will usually lead you towards the most appropriate administrative environment.

Trust Levels Bring Consistency

Earlier in this series I introduced the concept of Trust Levels.

Rather than selecting technology first, define the level of assurance required for the identity.

Once that’s understood, selecting the administrative environment becomes much simpler.

High trust identities receive higher assurance environments.

Lower trust identities receive proportionate controls.

This creates consistency across the organisation while avoiding unnecessary complexity.

We’ll explore this approach in much greater detail later in the series.

Key Takeaways

Choosing the right administrative environment isn’t about selecting the newest technology or following a generic best practice.

It’s about understanding risk.

The highest assurance identities deserve the highest assurance environments.

Other administrative roles may be appropriately protected using virtual PAWs or hardened managed devices.

The important thing is that these decisions are made deliberately, consistently and with a clear understanding of the risks involved.

What’s Next?

Choosing the right administrative environment is only the beginning.

Once you’ve selected the appropriate platform, the next challenge is ensuring it’s configured securely.

In the next article we’ll explore how to harden a modern Privileged Access Workstation using Microsoft Intune, Microsoft Defender, Windows security features and identity-based controls to build an administrative environment that is resilient against modern threats.
