Zero Trust for IT Administration: How Just-in-Time Access Replaces Permanent Administrator Accounts

The administrator account that nobody thinks about until something goes wrong

It usually starts with a routine task.

An IT administrator needs to restart a service, reset a password, modify a firewall rule, or deploy a configuration change. Their administrator account is already a member of several highly privileged groups, so the work takes only a few minutes.

The task is completed, but the privilege remains.

Days later, that same account is used for email, collaboration, web browsing, or connecting to another system. If an attacker compromises the account through phishing, credential theft, malware, or session hijacking, they inherit administrator rights immediately. What began as a standard operational convenience becomes a rapid path to broader compromise.

This is exactly the type of risk that Zero Trust aims to reduce.

Instead of assuming privileged users should always have administrative rights, Zero Trust asks a different question:

"Does this person need elevated privileges right now?"

If the answer is no, those privileges should not be active.

Why permanent administrator accounts create unnecessary risk

Traditional IT environments often rely on standing privileges, where administrator permissions are permanently assigned to user accounts.

This model was practical when infrastructure changed less frequently and most systems lived inside trusted corporate networks. Modern organizations operate very differently.

Administrators now manage:

- Microsoft 365 - Azure and hybrid cloud resources - Virtual machines - SaaS platforms - Identity systems - Remote endpoints - DevOps infrastructure

At the same time, attackers increasingly target identities rather than network perimeters.

The principles described in the National Institute of Standards and Technology's Zero Trust Architecture guidance emphasize continuous verification and minimizing implicit trust instead of relying on broad, persistent access. NIST also identifies least privilege as a foundational element of Zero Trust architectures.

Permanent administrative access conflicts with these principles because privileged permissions exist even when no administrative work is taking place.

How Just-in-Time access works

Just-in-Time access means privileged permissions are activated only when required and only for a limited period.

Instead of every administrator permanently holding elevated rights, access becomes a controlled workflow.

A typical process looks like this:

1. The administrator signs in using a standard account. 2. They request elevation for a specific privileged role. 3. The request may require multifactor authentication, approval, justification, or additional verification. 4. Administrative permissions become active for a defined period. 5. Access automatically expires after the task is complete.

This significantly reduces the amount of time privileged permissions exist within the environment.

Microsoft Entra Privileged Identity Management (PIM), for example, supports eligible role assignments with time-limited activation, approval workflows, multifactor authentication, and monitoring for Microsoft Entra, Azure, and Microsoft 365 administrative roles. Microsoft recommends minimizing permanent privileged assignments, with emergency access accounts being a carefully managed exception.

Zero Standing Privilege versus Just-in-Time access

These two concepts are closely related but are not identical.

Just-in-Time access limits how long privileges remain active.

Zero Standing Privilege goes one step further by aiming to eliminate permanent administrative permissions altogether for normal operations.

In practice, many organizations gradually move toward Zero Standing Privilege by introducing Just-in-Time access first.

That journey often delivers meaningful security improvements without requiring a complete redesign of identity infrastructure.

A practical example

Imagine a systems engineer who manages Azure virtual machines.

Under a traditional model, they are permanently assigned the Virtual Machine Contributor role.

Even during vacations, weekends, or while answering email, the account retains administrative permissions.

With Just-in-Time access:

- The engineer requests elevation only before maintenance begins. - Multifactor authentication confirms the request. - Access is granted for one hour. - Every activation is logged. - Privileges automatically expire when the maintenance window ends.

If that account is compromised outside the approved maintenance period, the attacker does not automatically receive administrative permissions.

The identity may still require investigation, but the attacker's ability to move deeper into the environment is substantially reduced.

More than security: Better operational visibility

Organizations often adopt Just-in-Time access for security reasons, but the operational benefits can be just as valuable.

Instead of asking:

"Who has administrator rights?"

IT leaders can answer more useful questions:

- Who activated administrator access? - Why was access requested? - Which role was activated? - How long did the elevation last? - Was approval required? - Are privileged roles actually being used?

These records support internal governance, investigations, audits, and continuous improvement.

Combining Just-in-Time access with other Zero Trust controls

Time-limited access is most effective when combined with additional identity protections.

Common controls include:

- Multifactor authentication for privileged role activation - Conditional Access policies based on device health, location, or risk - Approval workflows for highly sensitive roles - Access reviews to remove unnecessary eligibility - Logging and monitoring of privileged activities - Dedicated emergency access accounts that are tightly controlled and excluded from routine administration

Microsoft's guidance for privileged identity recommends using elevation procedures rather than maintaining unnecessary standing privileges, while protecting privileged operations with strong identity controls.

Why this matters for organizations across the GCC

Organizations across Saudi Arabia, the UAE, and Oman continue to expand their use of cloud services, Microsoft 365, hybrid infrastructure, and digital business platforms. As identity becomes the primary security boundary, privileged account management deserves the same attention as endpoint protection, network security, and cloud security.

For many organizations across the GCC and wider MENA region, replacing permanent administrator accounts with controlled, time-limited access is a practical way to strengthen cybersecurity without disrupting day-to-day operations. It also creates clearer audit trails, improves governance, and supports consistent oversight of privileged access as environments become more distributed and identity-centric.

Cyberactics regularly works with organizations that have invested in network and endpoint security while privileged identities still retain broad, permanent permissions. Reviewing administrative access is often one of the most effective steps in strengthening a broader Zero Trust strategy.

Challenges to expect

Moving away from permanent administrator accounts is usually more about operational change than technology.

Common concerns include:

- Administrators worrying that approvals will slow urgent work - Legacy applications requiring fixed permissions - Poor documentation of existing privileged roles - Service accounts with excessive permissions - Teams sharing privileged credentials

These issues can usually be addressed through phased implementation rather than attempting a complete migration all at once.

Many organizations begin with the highest-risk administrative roles before expanding Just-in-Time access across additional systems.

Building a realistic roadmap

Most successful projects begin with visibility rather than technology.

A practical roadmap often includes:

1. Identify every privileged account across cloud and on-premises environments. 2. Remove unnecessary administrator assignments. 3. Convert permanent administrators into eligible administrators where appropriate. 4. Require multifactor authentication for privileged activation. 5. Introduce approval workflows for sensitive roles. 6. Monitor privileged activity and regularly review role assignments. 7. Keep emergency access accounts separate, secured, and reserved for exceptional situations.

This incremental approach aligns with Zero Trust principles while allowing IT teams to maintain operational continuity.

Conclusion

Zero Trust is often summarized as "never trust, always verify," but for IT administration its practical meaning is even simpler:

Administrative privileges should exist only when they are genuinely needed.

Replacing permanent administrator accounts with Just-in-Time access reduces opportunities for attackers, improves visibility into privileged operations, and supports a more resilient identity security model without preventing administrators from doing their jobs.

For organizations across Saudi Arabia, the UAE, Oman, and the wider GCC, this shift represents a practical step toward modern identity security as cloud adoption and hybrid infrastructure continue to grow.

If your organization is reviewing privileged access across Microsoft, cloud, or hybrid environments as part of a Zero Trust initiative, Cyberactics can help assess your current approach and develop a practical roadmap toward time-limited, least-privilege access through cybersecurity, identity, and managed security services that fit your operational requirements. JIT access is often the first identity workflow SMBs codify inside a broader security automation program that removes standing privilege across the environment.
