Engineering, production, and IT systems are more connected than ever. CAD files move between workstations, PDM vaults, business systems, production equipment, cloud platforms, and outside suppliers. While these connections make it easier to collaborate and move designs into production, they also create more opportunities for sensitive information to be exposed or operations to be disrupted.
Security compliance in manufacturing requires an understanding of how engineering data moves, control of who can access it, securing the connection between IT and production, and preparing to recover critical systems without compromising CAD performance or production uptime. This article will help you identify common security gaps across your organization, prioritize improvements, and retain the evidence needed to demonstrate compliance.

Engineering and Manufacturing Security Compliance Checklist
Utilize this checklist to evaluate your organization’s current security protocols and identify any gaps that need further attention.
Engineering Data
- Identify where sensitive engineering data is stored, accessed, shared, and backed up.
- Map how files move between CAD, PDM, business systems, production equipment, and suppliers.
- Remove uncontrolled copies and access that is no longer needed.
CAD, PDM, and Workstations
- Encrypt sensitive data while stored and transferred.
- Control local downloads and use approved sharing platforms.
- Keep engineering software and workstations updated.
- Test security changes for compatibility and performance.
User and Vendor Access
- Require unique accounts and multi-factor authentication.
- Limit permissions according to role, project, and business need.
- Review access regularly and disable accounts promptly.
- Limit, monitor, and end remote vendor access after use.
IT and Production Systems
- Separate production systems from business and guest networks.
- Restrict IT/OT connections to approved users, devices, and applications.
- Identify and monitor connected or unsupported equipment.
Vulnerability Management
- Test patches before deploying them to engineering or production systems.
- Coordinate production updates with operations teams and equipment vendors.
- Create a replacement plan for unsupported technology.
Ransomware and Recovery
- Back up critical files, systems, and machine configurations.
- Establish the order in which systems should be restored.
- Test recovery procedures regularly.
- Verify designs and machine programs before resuming production.
Compliance Evidence
- Assign an owner to each security control.
- Retain access, patching, backup, training, and incident-response records.
- Review documentation regularly and replace outdated evidence.
- Conduct a cybersecurity assessment to identify and prioritize remaining gaps.
Identify Where Sensitive Engineering Data Lives
Before you can protect sensitive engineering data, you need to know everywhere it is stored, accessed, and shared. This is often more complicated than it appears. A CAD model may begin as an email attachment, move into a PDM system, connect to information in an ERP (Enterprise Resource Planning) or MES (Manufacturing Execution System) platform, generate instructions in CAM software, and eventually reach production equipment or an outside supplier.
Start by documenting how sensitive files move through your organization from the moment they are created through production, delivery, and archiving. Identify who can access the information, which systems process it, where copies are created, and when data leaves your controlled environment.
This process may uncover files stored outside approved systems, outdated user permissions, uncontrolled local copies, unencrypted transfers, or suppliers retaining access after a project ends. It can also help determine which parts of your IT environment fall within the scope of applicable compliance requirements.
Protect CAD, PDM, and Engineering Workstations
CAD models, drawings, simulations, and product specifications are some of your company’s most valuable assets. These files can also contain controlled information, depending on the industry. Protecting the systems used to create, store, and access them is therefore essential to security compliance.
Start by limiting CAD and PDM access according to each user’s role, project, and business need. Use unique accounts and multi-factor authentication for engineering systems, remote connections, and administrative access whenever supported. Sensitive data should also be encrypted both while stored and while being transferred.
Pay particular attention to local copies. Engineers may download files for performance, remote work, or offline access, but those copies can fall outside PDM version control, access restrictions, monitoring, and backup processes. Establish clear policies for when files may be downloaded, where they can be stored, and how they should be removed after a project.
Engineering workstations, operating systems, CAD software, PDM clients, and plugins must also be kept current. Because patches and security tools can affect application compatibility and performance, test changes against real engineering workflows before deploying them widely.
Security should not make engineering applications impractical to use. Poorly configured endpoint protection, VPNs, remote desktops, or cloud infrastructure can slow file access, disrupt PDM connections, and affect simulation or rendering.

Strengthen User, Administrator, and Vendor Access
Access controls determine who can view, modify, or share sensitive engineering and production data. When permissions are too broad or remain active longer than necessary, a compromised account can provide access to CAD files, PDM vaults, business systems, or production equipment.
Require each employee, administrator, contractor, and vendor to use a unique account. Multi-factor authentication should protect remote access, cloud platforms, administrative accounts, and other critical systems whenever supported. Avoid shared credentials because they make it difficult to determine who accessed a system or changed a file.
Follow the principle of least privilege by giving users only the access required for their current work. An engineer may need to modify files for one project but only view information for another. Likewise, routine work should be completed through standard accounts rather than accounts with administrator privileges.
Access should also change when people and projects do. Establish a consistent process for updating permissions when an employee changes roles and immediately disabling accounts when an employee or contractor leaves. Periodic access reviews can identify inactive accounts, unnecessary privileges, and former vendors that still have remote connections.
Vendors may require remote access to troubleshoot production systems. Their access should be approved for a specific purpose, limited to the necessary equipment, monitored during use, and disabled when the session ends. Avoid leaving permanent remote connections active for occasional maintenance.
Secure the Connection Between IT and Production Systems
Manufacturing operations increasingly depend on connections between information technology (IT) systems and operational technology (OT). These connections improve productivity and data sharing, but they can also allow a security incident to spread from a business network to the production floor.
Network segmentation limits that risk by separating production systems from business, guest, and public networks. Communication between IT and OT should be restricted to approved devices, users, ports, and applications.
A Cybersecurity Risk Assessment can help identify vulnerabilities across networks, systems, access controls, and connected devices. CADimensions partners with Advance2000 to provide these and other services specialized to meet the needs and requirements of engineering and manufacturing teams.
Manage Vulnerabilities Without Interrupting Engineering or Production
Regular security updates are essential. Before deploying updates widely, test them with representative CAD assemblies, PDM workflows, simulation tools, machine connections, and other critical applications. Coordinate changes to production equipment with operations teams and equipment vendors to confirm compatibility and schedule maintenance during planned downtime.
Over time, some systems may no longer receive security updates or support modern security. Unsupported systems should ultimately be included in a technology replacement plan. Prioritize replacements according to security risk, operational importance, vendor support, and the potential consequences of failure.
Prepare for Ransomware and Production Disruptions
Ransomware attacks can be devastating to your business. They can make CAD files and PDM vaults inaccessible, interrupt connected equipment, delay production, and prevent teams from confirming whether designs or machine programs were altered.
A recovery plan should identify which systems must be restored first to resume critical operations. Priorities may include identity and network services, PDM, ERP, MES, quality systems, production data, and machine configurations. Document how long each system can remain unavailable and how much recent data the organization can afford to lose.
Collect the Evidence Needed to Demonstrate Compliance
Implementing security controls is only part of compliance. Manufacturers may also need to prove that those controls are documented, consistently followed, and reviewed over time. Evidence may be requested during a customer security review, cyber insurance renewal, internal audit, or formal compliance assessment. Waiting until that request arrives can leave teams searching through emails, screenshots, spreadsheets, and system logs for proof.
Assign an owner to each control and define what evidence must be retained. Store policies, reports, approvals, test results, and remediation records in a controlled location. Each item should include a review date so outdated documentation can be identified and replaced.
