Lessons from the Field
Over the years, I’ve seen just about everything in ERP security. This article distills Acumatica security best practices into a practical guide you can apply today.
I’ve walked into companies where the office assistant had access to the CEO’s financial dashboards.
I’ve seen organizations where every user — from accounting interns to warehouse staff — had the Administrator role.
And I’ve worked with businesses where access control became so tangled that no one could explain who could do what inside the system.
None of these issues come from bad intentions. They come from a lack of structure and from underestimating how critical security management is in Acumatica.
ERP security isn’t only about outside threats. It’s about controlling visibility, responsibility, and accountability inside your organization. A weak permission model creates risk, slows workflows, weakens governance, and makes compliance nearly impossible. The aim of Acumatica security best practices is to avoid exactly that.
In this guide, you’ll find the essential security controls and audit practices every Acumatica user should know, with real-world cases (industry names changed) and how KALM Consulting aplica su marco R.E.S.C.U.E. para ordenar y sostener la seguridad.
When Everyone Can See Everything: Common ERP Security Pitfalls
Security mistakes in ERP environments often start small and grow. Most companies begin with default roles during implementation. At first they work — convenient, functional, aligned to basic operations. As the business matures, people ask to “tighten” access. That’s when trouble starts and Acumatica security best practices get ignored.
Three common patterns:
The “Security Expert Trap”
One person (IT or Accounting) becomes the only one who understands permissions and roles. When that person leaves, no one can maintain the model.
The “Admin Creep” Problem
Roles get so complex that admins, overwhelmed by requests, grant module-level admin rights to speed things up — creating de facto administrators across the ERP.
The “Role Explosion” Scenario
Over time, users collect overlapping roles. A sales rep finishes with Admin rights for Sales, Inventory, Payments, and Finance — effectively owning the keys to the ERP.
Real Scenarios from the Field
🧑💼 The “Everyone’s an Admin” Problem
A mid-sized distributor grew fast and, to simplify onboarding, IT gave everyone the same Administrator role. Within months, a warehouse operator changed several sales prices directly in ERP. Not malicious — but it caused pricing inconsistencies across the system. The audit trail named the operator, but the security design made the trail meaningless because every user had unrestricted capabilities. A textbook failure against Acumatica security best practices.
🧾 The Shared User Account Trap
In a retail company, several accounting employees used the same “FinanceUser” login. It felt convenient until a fraudulent payment slipped through. When questioned, nobody could confirm who approved it. The team later tied the transaction to a deactivated vendor from an ex-employee.
🔓 The Forgotten Access Problem
In a manufacturer, a developer who left two years earlier still had active API credentials tied to an integration. No one dared disable it. It became a permanent backdoor — unnoticed until a major audit.
These aren’t rare. They come from weak access policies, a lack of routine audits, and permissive defaults that ignore Acumatica security best practices.
Why Security in Acumatica Is Different (and Critical)
Acumatica’s flexibility is a strength and a risk. In a cloud ERP, security is about who can access what, from where, and under which context. Every role, permission, and branch access rule matters. One unchecked right can compromise:
- Sensitive customer and financial data
- Workflow integrity and approvals
- Traceability and audit confidence
- Compliance (SOX, GDPR, ISO, etc.)
Done right, Acumatica security best practices don’t “lock users out.” They build a culture of controlled trust.
Acumatica’s Core Security Controls: What Every Admin Should Master
1) Role-Based Access Control (RBAC)
Acumatica’s model is role-centered — not user-centered.
Best practices:
- Build roles around functions, not people (“AP Clerk” vs. “John Smith”).
- Assign permissions to roles, never directly to users.
- Review roles quarterly against actual responsibilities.
- Avoid Administrator unless strictly required.
- Remove old roles before adding new ones to prevent stack-ups.
Tip: Formalize a change request for any role update. It’s a lightweight habit that enforces Acumatica security best practices without bureaucracy.
2) Segregation of Duties (SoD)
No user should perform conflicting actions (e.g., create a vendor and approve payments to that vendor).
Use Acumatica tools: Access Rights by Screen, Audit History, and inquiries to spot conflicts.
Typical SoD violations:
- Access to both “Bills and Adjustments” and “Check Printing.”
- Rights to “Inventory Receipt” and “Inventory Adjustment.”
- Approvers who can edit transactions after approval.
Implement SoD matrices and test them quarterly.
3) Password and Authentication Policies
Strong credentials are non-negotiable.
Recommendations:
- Enforce MFA for all users.
- Require complex passwords (12+ chars) with 90-day rotation.
- Limit failed attempts; enable lockouts.
- Auto-disable inactive users after 60 days.
- Use SSO/IdP where possible to centralize controls.
These basics anchor Acumatica security best practices and reduce easy wins for attackers.
4) Field-Level and Data-Level Security
Not everyone should see the same data.
- Apply Row-Level Security (RLS) to restrict records by branch/company/unit.
- Hide sensitive fields (salary, standard cost, margins) by role.
- Segment reporting folders and GI access by department.
5) System Audit and Activity Logs
You can’t manage what you don’t monitor.
Best practices:
- Review Audit History monthly.
- Export to Excel/Power BI to visualize anomalies.
- Flag unusual behavior (after-hours logins, high edit volumes).
- Retain logs per your compliance horizon.
Auditing operationalizes Acumatica security best practices and proves governance.
Building a Culture of Security Through Regular Audits
Technology sets rules. People uphold them. Regular audits prevent “security drift.”
Quarterly Security Audit Checklist:
- User Access Review: Validate each user’s roles vs. job duties.
- Dormant Account Cleanup: Disable inactive accounts.
- Role Audit: Remove overlaps and conflicts; reduce admin rights.
- Integration Review: Validate API/service accounts and tokens.
- Policy Verification: Confirm MFA, password rotation, and lockouts.
- SoD Testing: Re-run conflict checks after org/process changes.
Document findings, assign owners, set due dates, and track remediation to closure. Repeat. That’s how Acumatica security best practices become habit.
How We Approach ERP Security at KALM
At KALM Consulting, we’ve seen “security chaos” develop quietly — and how to reverse it with structure. Our R.E.S.C.U.E. Framework makes security clear, practical, and sustainable.
1) Research — Understand the Current State
We analyze roles, access rights, SoD risks, and actual user behavior/logs.
2) Engage — Map Roles to Real Responsibilities
We meet leaders to align duties, data needs, and minimization. Principle of least privilege is baseline for Acumatica security best practices.
3) Stabilize & Clarify — Identify Risks and Gaps
We surface overlapping permissions, admin overuse, shared accounts, and config weaknesses — then contain them quickly.
4) Upgrade & Empower — Build a Maintainable Model
We redesign roles, implement audit rhythms, and document everything. Then we train your team to maintain security confidently — without future dependency.
Outcome: a secure, auditable Acumatica where every user has the right access, for the right reason, at the right time.
Quick Wins You Can Apply This Week
- Replace any shared logins with individual accounts + MFA.
- Inventory Admin rights; replace with scoped roles.
- Auto-disable users after 60 days of inactivity.
- Create a “Read-Only Finance” role for reporting without edit rights.
- Stand up a monthly 30-minute Access Review meeting.
- Tag integrations and rotate API keys on a defined cadence.
Small steps compound into Acumatica security best practices that hold under pressure.
Final Thoughts: Security Is Not Optional — It’s Foundational
ERP security isn’t about paranoia. It’s professionalism. Most ERP risks don’t come from hackers — they come from inside: mismanagement, oversight, or unclear responsibility.
