ERP Security Posture Checklist: 30 Controls That Protect Your System of Record
This free ERP security posture checklist walks IT leaders and plant managers through 30 concrete, evidence-based controls that protect the system holding your orders, BOMs, pricing, and financials. It is organized into five domains (access control, patching, network, data protection, and monitoring) with the highest-risk items explicitly flagged as critical. It is written for manufacturers running Infor SyteLine, LN, Baan, and similar on-prem or hosted ERP systems, where a compromise does not just leak data; it stops production. Work through it in fifteen minutes and you will know exactly where your system of record is exposed.

8 critical items still open - these are the highest-risk gaps.
Access Control and Identity
Patching and Vulnerability Management
Network and Infrastructure
Data Protection and Backup
Monitoring and Response
Score yourself honestly: an item counts only if it is true today and you could show evidence. Critical items represent the controls most commonly exploited in real manufacturing breaches; any unchecked critical item deserves remediation ahead of everything else, regardless of your overall percentage.

How the checklist is built and scored
Each item is a binary, evidence-based control: either it is true today and you could demonstrate it to an auditor, or it is unchecked. The critical flags mark the eight controls that map most directly to how manufacturing ERP environments actually get compromised: shared logins that defeat accountability, unpatched internet-adjacent services, flat networks that let ransomware jump from a phishing victim's laptop to the ERP database, and backup sets reachable from the same compromised domain they are meant to protect. Your percentage matters less than your critical-item count. A 70 percent score with two open critical items is a worse position than 55 percent with all criticals closed, because attackers exploit specific gaps, not averages.
Why manufacturing ERP is a priority target
Manufacturers have become a top-targeted sector for ransomware precisely because downtime is unaffordable: when the ERP is encrypted, shipping stops, and attackers price their demands accordingly. ERP environments compound the exposure in predictable ways.
- Long upgrade cycles leave many plants running ERP versions, databases, or operating systems past security support
- Shop-floor culture normalizes shared terminals and generic logins, erasing the audit trail identity controls depend on
- Decades of integrations (EDI, label printing, quality systems, spreadsheets with embedded credentials) create unmapped pathways into the database
- Backups are frequently online and domain-joined, which is why modern ransomware crews encrypt or delete them first
Interpreting your results and sequencing remediation
Triage in three passes. First, close every unchecked critical item; most (MFA on remote access, backup immutability, deactivation discipline, network segmentation of ERP servers) are configuration and process work measured in weeks, not capital projects. Second, address the cheapest remaining items in access control and monitoring, because they compound: named accounts make log review meaningful, and log review makes every other control verifiable. Third, schedule the structural items (patching cadence, segmentation redesign, version upgrades) into the budget cycle with the checklist as your evidence. Re-run the checklist quarterly; posture decays through staff turnover and new integrations, and a falling score is the earliest warning you will get.
How Netray hardens ERP environments
Netray secures ERP environments from inside the application, which is where generic security vendors stop. We remediate at the ERP layer: rebuilding role models with segregation of duties, eliminating shared logins without disrupting shop-floor workflows, locking down direct database access that legacy reports and spreadsheets depend on, and re-architecting integrations onto authenticated APIs. On the infrastructure side we implement segmentation, immutable backup patterns, and ERP-aware log monitoring, and because we support SyteLine, LN, and Baan daily, hardening lands without breaking MRP, EDI, or month-end. For aerospace and defense clients we align the same controls to CMMC and ITAR handling requirements, so one remediation effort serves both security and compliance.
Frequently Asked Questions
Which items should we fix first if resources are tight?
The critical-flagged items, in roughly this order: an offline or immutable backup copy with a tested restore, MFA on all remote and admin access, elimination of shared logins, same-day deactivation of departed users, network segmentation of ERP servers, and patch currency on anything internet-adjacent. These six controls interrupt the most common real-world attack chains against manufacturers and are mostly process and configuration work rather than major purchases.
Our ERP is on-prem and not exposed to the internet. Are we already safe?
No, and this assumption is how most manufacturing ERP incidents start. The typical path is a phishing email compromising an office workstation, credential theft, and lateral movement across a flat network to the ERP database, none of which requires the ERP itself to be internet-facing. Segmentation, least-privilege service accounts, restricted database access, and unreachable backups are exactly the controls that break that chain, which is why they carry critical flags.
How does this checklist relate to CMMC or NIST requirements?
It is deliberately aligned but not a substitute. The access control, monitoring, and data protection items map directly onto NIST 800-171 families that CMMC assesses, so closing them advances both security and compliance simultaneously. However, CMMC additionally requires documented policies, evidence collection, and formal assessment scope. Defense suppliers should treat this checklist as the practical hardening layer and pair it with a proper gap assessment against the applicable CMMC level.
