Executive Order 14028 accelerates zero trust and identity hardening

At a glance

What this is: This is Axiad’s analysis of Executive Order 14028 and its push toward zero trust, stronger incident disclosure, and tighter software and supplier security.

Why it matters: It matters because federal pressure on zero trust and shared accountability tends to reshape IAM, contractor access, and identity controls well beyond government agencies.

By the numbers:

• The Biden administration wants to leverage the federal government's $70 billion IT budget to encourage better security practices.

Context

Executive Order 14028 is a policy response to the gap between modern cyber risk and older security assumptions. In identity terms, it pushes organisations away from one-time trust decisions and toward continuous verification, stronger disclosure, and tighter software and supplier accountability.

Although the article is framed around federal policy, its practical importance extends to IAM, PAM, and NHI governance because contractor access, software supply chains, and authentication controls all sit inside the same trust boundary. The organisations that feel this first are often the ones that already depend on third parties, cloud services, and distributed access models.

Key questions

Q: How should organisations apply zero trust principles to identity controls?

A: Start by treating identity as a continuous risk decision rather than a one-time login event. Re-evaluate access at sensitive actions, high-value systems, and supplier boundaries. The most effective programmes combine strong authentication, least privilege, rapid revocation, and logging that shows when trust changed, not just when access began.

Q: Why do contractor and supplier identities matter in zero trust programmes?

A: Because external identities often have real access to code, infrastructure, or sensitive data. If those identities are not reviewed, revoked, and scoped like internal accounts, they become a hidden extension of the enterprise trust boundary. Zero trust fails when third-party access is treated as exceptional instead of governed.

Q: What breaks when access reviews do not include machine identities?

A: The review process misses the accounts that often perform the most sensitive actions, including service-to-service calls, deployments, and integrations. That creates stale privileges, orphaned credentials, and unowned access paths. In practice, the organisation believes it has reviewed access while its automation layer still carries unresolved privilege.

Q: Who is accountable when exposed credentials or weak supplier controls lead to an incident?

A: Accountability should sit with the system owner, the identity governance team, and the supplier manager together, because the failure is usually shared across lifecycle, access, and oversight. The right question is not who owns the blame, but who can revoke access, validate scope, and prove the controls worked.

Technical breakdown

Zero trust architecture changes the identity trust model

Zero trust shifts identity from a perimeter-based assumption to a continuous verification model. Instead of trusting a session, device, or network location once, access decisions are meant to reflect current risk, current context, and current entitlement. That matters because passwords and long-lived session trust are weak proxies for actual assurance. In practice, zero trust does not mean every request is blocked. It means identity, device, and resource state must be re-evaluated often enough that compromise is harder to turn into persistent access.

Practical implication: map your current authentication and authorisation flows to continuous verification points, not just login checkpoints.

Incident and vulnerability playbooks become identity controls

The EO ties incident response and vulnerability response to more disciplined reporting and corrective action. That is an identity issue because compromised accounts, exposed credentials, and stale entitlements are often the first thing attackers exploit after an initial foothold. A playbook is only useful if it defines who can revoke access, how quickly credentials can be disabled, and which services must be checked after disclosure. Without those steps, response is descriptive rather than operational, and the attacker keeps access longer than the organisation keeps visibility.

Practical implication: ensure every response playbook includes identity revocation, credential rotation, and contractor offboarding steps.

Software supply chain scrutiny extends to machine identities

The article’s discussion of suppliers, code provenance, and software transparency points directly to machine identity risk. Service accounts, API keys, certificates, and CI/CD credentials are often embedded in delivery pipelines and vendor-managed systems, which makes supplier trust part of identity trust. If a contractor, build system, or software provider can access code or infrastructure, then identity governance must extend beyond employees. That means entitlement review, access scope, and offboarding discipline have to reach into the supply chain, not just the internal directory.

Practical implication: include third-party service accounts, API keys, and build identities in access reviews and offboarding.

NHI Mgmt Group analysis

EO 14028 is really a trust-reset order, not just a compliance update. The article focuses on federal systems, but the deeper issue is that static trust assumptions are no longer defensible in distributed environments. When access, software, and incident response all depend on external suppliers, the boundary between policy and identity governance disappears. The implication is that programmes still built around periodic authentication checks are operating on an outdated trust model.

Zero trust is only meaningful if identity decisions move as fast as the attack surface. The article correctly links zero trust to stronger authentication, but identity teams should see the broader pattern: trust must be reassessed at the pace of supplier changes, access changes, and software changes. That is where IAM, PAM, and contractor governance intersect. Practitioners should treat zero trust as an operating model for access decisions, not a product category.

Supplier access is now an identity governance problem, not just a procurement concern. The EO’s emphasis on software providers and information sharing makes vendor oversight part of the access-control conversation. If third parties can build, sign, deploy, or support systems, then their identities become part of the threat surface. The practical conclusion is that access reviews and offboarding must extend to external service identities, not stop at the employee directory.

The strongest control signal in this policy shift is revocation speed. The article repeatedly points toward better response, stronger disclosure, and more disciplined security practices, which all fail if access lingers after compromise. In identity programmes, the critical question is no longer whether access was granted appropriately, but how quickly it can be removed when trust changes. Teams should measure revocation as a core security outcome.

From our research:

• 91.6% of secrets remain valid five days after the targeted organisation is notified, showing a critical gap in remediation procedures, according to Ultimate Guide to NHIs.
• Only 5.7% of organisations have full visibility into their service accounts, which means most identity teams cannot reliably see the machine identities they are expected to govern.
• If this policy shift is pushing your programme toward tighter lifecycle control, review 52 NHI Breaches Analysis for the breach patterns that make revocation speed matter.

What this signals

Revocation speed is becoming the practical test of identity maturity. Policy statements about zero trust matter less than how quickly teams can remove access after trust changes. With 91.6% of secrets still valid five days after notification, according to Ultimate Guide to NHIs, many programmes are still too slow to match real attacker timelines.

The next governance gap will be supplier identity visibility, especially where build systems, managed services, and contractor access overlap. If your access reviews stop at employees, your control environment is already incomplete.

Supplier trust debt: when third-party identities are not lifecycle-managed like internal accounts, the organisation inherits their exposure without inheriting their discipline. That is where zero trust becomes a slogan instead of an operating model.

For practitioners

• Harden zero trust checkpoints Review authentication and authorisation paths to ensure access is re-evaluated at critical system boundaries, not only at initial login. Focus on privileged applications, sensitive data stores, and contractor entry points.
• Extend identity controls to suppliers Inventory third-party service accounts, API keys, certificates, and support identities that can reach internal systems. Put them into the same access review and offboarding process used for internal identities.
• Build revocation into incident playbooks Add explicit steps for credential disablement, access removal, and downstream dependency checks whenever a cyber event or vulnerability disclosure occurs. Assign ownership before the incident happens.
• Align software provenance with identity governance Require teams to know where source code, build credentials, and deployment identities originate, then tie that information to supplier risk reviews and software release approvals.

Key takeaways

• EO 14028 matters to identity teams because it turns zero trust, disclosure, and supplier accountability into operational access-control problems.
• The hardest part of this shift is not authentication at login, but revocation, review, and offboarding across both internal and third-party identities.
• Programmes that cannot see or rapidly remove machine and supplier access will struggle to meet the trust expectations this policy direction creates.

Key terms

• Zero Trust Architecture: A security model that assumes trust must be continuously earned rather than granted once at login. In identity programmes, it means access decisions should be rechecked against context, privilege, and risk whenever a user, service, or supplier tries to reach a protected resource.
• Machine Identity: An identity used by software, infrastructure, or automation rather than a person. It includes service accounts, API keys, certificates, and other non-human credentials that authenticate systems, support workflows, and often carry privileges that must be governed through lifecycle controls.
• Identity Revocation: The act of removing or disabling access when an identity is no longer trusted, needed, or valid. In practice, revocation must cover credentials, sessions, tokens, certificates, and downstream dependencies, or the organisation may believe access is gone when it is still active.
