Role Based Access

This topic is part of the SG Systems Global regulatory & operations glossary.

Updated December 2025 • Permissions, Segregation of Duties & Auditability • IT, QA, Operations, Compliance

Role based access (often called RBAC) is a security and governance model where user permissions are assigned through defined roles rather than granted ad hoc to individuals. Instead of “give Stuart access to these 37 screens,” you define roles such as “Warehouse Receiver,” “QA Reviewer,” “Production Operator,” or “System Administrator,” and you grant each role the minimum permissions needed to perform that job. Users then inherit permissions by membership in those roles, and changes to access happen through controlled role assignment workflows. In regulated manufacturing software, RBAC is not just IT hygiene—it is a compliance control that supports attribution, prevents unauthorized changes, and helps enforce data integrity and attributable audit trails (including Part 11/Annex 11 expectations where applicable).

RBAC exists because uncontrolled access creates predictable failure modes: people can approve their own work, edit records after the fact, bypass holds and quarantines, overwrite master data, or create “ghost” transactions that destroy traceability. In high-consequence environments, access is part of the quality system. If you cannot prove that only authorized roles can create, modify, approve, release, and disposition records, your electronic system becomes difficult to defend during audits and investigations. RBAC is how you turn security into a repeatable, inspectable operating discipline.

“If everyone can do everything, your system isn’t controlled—it’s just documented.”

1) What RBAC Controls in Manufacturing Systems

In manufacturing software, RBAC typically controls both actions and data scope. Actions include who can create records, edit records, approve records, release status, perform overrides, or configure the system. Data scope includes what sites, lines, products, warehouses, or records a role can view or operate on. A warehouse receiver might create goods receipt transactions and place lots into quarantine, but they should not be able to release those lots. A QA reviewer might release lots, approve deviations, and sign off batches, but they should not be able to change the underlying master recipe configuration without change control.

RBAC also supports “defensible error prevention.” If the system blocks an action by design (because the role lacks permission), you reduce reliance on training and good intent. That is exactly what regulated environments prefer: controls that are enforced, not just explained.

2) RBAC vs User Access Management (UAM)

RBAC is the permission model. User access management (UAM) is the operational lifecycle that administers it: request, approval, provisioning, changes, deprovisioning, and periodic review. You can have RBAC defined on paper and still have weak control if access management is informal. Conversely, you can have strong access management processes but weak RBAC design if roles are poorly constructed or overly broad.

In practice, the two must work together. RBAC defines the roles and permissions. UAM defines how people get into roles, how those assignments are approved, and how you prove that access is correct over time. When auditors ask “who can do this action,” you need to answer with role definitions and evidence of role assignments, not with “we trust our team.”

3) Least Privilege: The Non-Negotiable Principle

Least privilege means users receive the minimum access needed to perform their job—no more. It’s not about being restrictive for the sake of it; it’s about reducing attack surface and reducing the chance of accidental or intentional misuse. In regulated operations, least privilege also reduces the scope of integrity risk. If a role cannot edit released batch records, you reduce the risk of post-hoc record manipulation. If a role cannot change master specs, you reduce the risk of silent spec drift.

Least privilege should be applied in layers:

• Role scope: roles are designed around job functions, not individuals.
• Permission scope: permissions are granular enough to separate high-risk actions (release, override, approve, configure) from routine actions (view, record, scan, print).
• Data scope: roles are limited to relevant sites/warehouses/lines where applicable.
• Time scope: temporary access is time-bounded; elevated access is not permanent.

When least privilege is ignored, roles become “superuser by default.” That is the most common RBAC failure mode and the fastest way to destroy defensible controls.

4) Segregation of Duties (SoD): Preventing Self-Approval

Segregation of duties means no single person should be able to execute all steps in a controlled workflow that would allow fraud or undetected error. In regulated manufacturing, SoD is often about preventing self-approval and preventing the same person from creating and releasing controlled records. Typical SoD separations include:

• Create vs approve: the role that creates a deviation, CAPA, or change request should not be able to approve it.
• Execute vs release: production can execute steps, but QA releases lots and batches (see batch release and release readiness concepts).
• Quarantine/hold vs release: warehouse can place holds; QA (or designated quality roles) release holds.
• Master data authoring vs production execution: engineering/quality authors; operations executes; change control governs updates.
• Admin vs business roles: system admin can configure but should not perform business approvals without justification and controls.

SoD is not absolute in small organizations. Sometimes a person must wear multiple hats. In those cases, RBAC should still enforce compensating controls: additional approval layers, review by exception, stronger audit trail monitoring, and documented justification for combined roles.

5) Permission Categories That Matter Most

Not all permissions carry equal risk. A defensible RBAC model separates permissions into categories and treats “high impact” permissions as special:

• Data entry: create and record events (receiving, dispensing, counts, inspections).
• Edit rights: ability to edit records, especially after completion or approval.
• Status changes: quarantine/hold release, disposition changes, batch status transitions.
• Approvals & e-signature: approval rights and electronic signatures (Part 11 relevance).
• Overrides: ability to bypass hard gates, accept exceptions, or force completion of steps (see hard gating concepts).
• Master data/configuration: recipes, specs, workflows, tolerance limits, label templates, and system parameters.
• Reporting/export: ability to export sensitive data or generate regulatory evidence packages.
• Administration: user creation, role creation, password policies, and audit trail configuration.

The RBAC design becomes defensible when these categories map to role responsibilities and approval controls. If every supervisor role includes “admin + approval + override,” your control story collapses quickly in audits.

6) RBAC and Data Integrity (Why Auditors Care)

Auditors care about RBAC because it directly impacts data integrity. If a user can modify records after the fact without detection, the record is no longer trustworthy. If someone can approve their own changes, the approval is weak. If admin privileges are widespread, audit trail value declines because too many people can alter the system configuration that defines what is captured.

RBAC supports data integrity through three mechanisms:

• Prevention: block unauthorized actions by design.
• Attribution: ensure all actions are tied to unique user identity and role membership.
• Detectability: maintain audit trails that show who did what and when, including role assignment changes.

RBAC is also a foundational control for trustworthy audit trails. The audit trail is only meaningful if access to modify records and configurations is limited and reviewable.

7) Provisioning and Deprovisioning: The Lifecycle Controls

RBAC is a living system because people change jobs, leave the company, or take on temporary duties. A controlled access lifecycle includes:

• Request: access request with justification tied to job role.
• Approval: approval by a responsible manager and, for high-risk roles, QA/IT security approval.
• Provisioning: role assignment, identity verification, MFA where applicable, and initial credential setup.
• Change control: role changes documented and reviewed; temporary roles time-boxed.
• Deprovisioning: immediate removal upon termination or job change; disable accounts promptly.
• Periodic review: recurring access reviews to confirm role membership remains correct.

The most dangerous RBAC failures occur during transitions: an employee moves departments but keeps old access, a contractor retains access after a project ends, or an admin role remains assigned “just in case.” Those are predictable control breaks. Periodic access reviews and time-bounded privileges prevent them.

8) Designing Roles That Don’t Explode Over Time

Role design is where most systems degrade. Common role design pitfalls include:

• Too many roles: hundreds of roles become unmaintainable, leading to confusion and privilege sprawl.
• Too few roles: broad “Power User” roles grant excessive access.
• Roles named after people: “Jane Role” is a control failure; roles should map to job functions.
• Inconsistent permissions: similar roles have different permissions due to ad hoc additions over time.
• Emergency access becomes permanent: “temporary” overrides never removed.

A stable model usually uses a small number of core roles per function and adds controlled “capability bundles” for specialized tasks. Role changes should route through change control when they affect regulated workflows because changing access changes the effective controls of the system.

9) RBAC and Electronic Signatures

In environments where electronic signatures are used, RBAC becomes even more critical. An electronic signature is only meaningful if the signer is uniquely identified and authorized to perform that approval action. RBAC supports this by restricting signature rights to specific roles and by ensuring those roles are assigned through controlled processes. A robust model typically separates “view” access from “sign” access and ties signature events into the audit trail.

Where e-signatures support batch release, deviation closure, CAPA approval, or change control approval, RBAC is a key part of the compliance argument: only authorized roles can sign; signatures are attributable; and the record cannot be altered after signing without traceable evidence.

10) Monitoring and Review: RBAC Is Not Set-and-Forget

RBAC needs monitoring because access is a moving target. A mature program includes:

• Periodic role review: confirm roles still match processes and risk models.
• Access review audits: review who is in high-risk roles, confirm justification, remove stale access.
• Audit trail review: monitor high-risk events (role changes, admin actions, overrides, post-approval edits).
• Exception reporting: identify unusual access patterns or repeated override behavior (ties to exception-based review concepts).

Without monitoring, RBAC degenerates into “whatever was needed at the time,” and that eventually becomes a compliance and security issue. Monitoring provides feedback to tighten roles, reduce unnecessary access, and identify process gaps that cause people to request elevated privileges.

11) Common Failure Modes (How RBAC Breaks in Real Plants)

RBAC programs usually break in predictable ways:

• Shared accounts: destroys attribution and makes audit trails weak.
• Overuse of admin roles: too many admins means configuration and record integrity can’t be defended.
• Broad supervisor permissions: supervisors become able to override everything, which turns controls into suggestions.
• No deprovisioning discipline: ex-employees retain access; contractors remain active.
• Role creep: permissions added over time “just to get the job done,” never removed.
• Weak segregation of duties: create/approve/release powers combined in one role without compensating controls.

These failure modes are not theoretical. They show up as audit findings, investigation weakness, and traceability gaps. The fix is governance: define roles, control changes, review access, and treat high-risk permissions as controlled items.

12) How This Fits with V5 by SG Systems Global

V5 Platform Control. In the V5 platform, RBAC supports governed execution across modules: WMS receiving and movement controls, MES batch execution and sign-offs, and QMS approvals, deviations, and CAPA. Role-based permissions can enforce who can create, approve, release, and override, with attributable audit trails.

Auditability and Review. Because actions and role assignments are recorded, RBAC in V5 supports inspection readiness: you can show who had access, who performed approvals, and whether segregation of duties is enforced. Changes to roles and permissions can be governed through controlled workflows and reviewed as part of internal audits.

Bottom line: RBAC is how V5 turns “policy” into “enforced behavior.” It reduces integrity risk, supports Part 11/Annex 11-aligned attribution, and strengthens the defensibility of every electronic record captured in the system.

13) FAQ

Q1. Why is RBAC important in regulated manufacturing?
Because it enforces who can create, modify, approve, and release regulated records. RBAC supports data integrity, prevents unauthorized changes, and makes audit trails defensible.

Q2. How many roles should we have?
Enough to separate high-risk actions (approval, release, overrides, configuration) from routine execution, but not so many that the model becomes unmanageable. Stable systems use a small set of core roles plus controlled capability bundles.

Q3. What is segregation of duties in RBAC?
It means one person should not be able to execute all steps of a controlled workflow, such as creating and approving the same record or releasing a hold they initiated, without compensating controls.

Q4. Are shared accounts acceptable?
No. Shared accounts destroy attribution and weaken audit trails. Unique user identity is essential for defensible electronic records and signatures.

Q5. How often should access be reviewed?
On a defined cadence and whenever roles change. High-risk roles should be reviewed more frequently. Periodic access reviews prevent role creep and stale access.

Q6. What permissions are most sensitive?
Admin/configuration rights, approvals/e-signatures, override rights, post-approval edit rights, and status change rights (quarantine/hold release, batch disposition). These should be tightly controlled and monitored.
