How to Make Your Engineering Firm Protect Client Data Using NIST Guidelines

 

Engineering firms handle sensitive client information including proprietary designs, infrastructure specifications, and intellectual property that requires robust protection. The National Institute of Standards and Technology (NIST) provides frameworks specifically relevant for safeguarding this data. Here's how to implement these protections in your engineering environment:

 

Understanding Your Engineering Firm's Data Security Needs

 

• Engineering firms handle unique sensitive data including CAD drawings, BIM models, structural calculations, and site surveys
• Many projects involve critical infrastructure information that could create security vulnerabilities if compromised
• Engineering data often requires long-term retention while maintaining accessibility and integrity
• Projects typically involve multiple external partners (contractors, clients, regulatory bodies) requiring secure collaboration

 

Step 1: Identify and Categorize Engineering Data

 

• Create an inventory of data assets specific to your engineering disciplines (structural, civil, electrical, etc.)
• Classify information according to NIST FIPS 199 categories (Low, Moderate, High) based on:
  • Confidentiality: Client proprietary specifications, preliminary designs, bid documents
  • Integrity: Structural calculations, safety analyses, testing results
  • Availability: Project timelines, resource allocations, regulatory submissions
• Determine if you handle any Controlled Unclassified Information (CUI) like critical infrastructure details that require NIST 800-171 compliance

 

Step 2: Apply the NIST Cybersecurity Framework to Engineering Workflows

 

• Identify: Document where engineering data resides across:
  • Design software environments (AutoCAD, Revit, SolidWorks)
  • Project management platforms
  • File-sharing services used with clients
  • Email systems containing project communications
• Protect: Implement safeguards for engineering-specific systems:
  • Secure remote access for field engineers and distributed teams
  • Version control systems that track design changes with integrity verification
  • Role-based access controls based on project assignments
• Detect: Monitor for suspicious activities in engineering environments:
  • Unusual access to proprietary designs or specifications
  • Abnormal file transfers of CAD or modeling files
  • Unauthorized modifications to calculations or specifications
• Respond: Create engineering-specific incident procedures:
  • Protocols for handling compromised design documents
  • Communication plans for notifying affected clients
  • Documentation procedures for potential project impacts
• Recover: Develop recovery processes for engineering data:
  • Restoring design files from secure backups with version history
  • Validating integrity of recovered calculations and specifications
  • Procedures for rebuilding project documentation if necessary

 

Step 3: Implement Basic Security Controls (NIST 800-53)

 

• Access Control: Limit access to engineering data on a need-to-know basis:
  • Require unique user accounts for all design software
  • Implement project-based permissions in document management systems
  • Use multi-factor authentication for remote access to project resources
• Data Protection: Safeguard engineering files and communications:
  • Encrypt sensitive design files both in storage and when shared externally
  • Implement secure file transfer protocols for sending large CAD files to clients
  • Create watermarking procedures for draft designs shared with clients
• System Integrity: Ensure engineering systems remain trustworthy:
  • Keep CAD/CAM software updated with security patches
  • Validate calculation software with test cases after updates
  • Implement change management for engineering software configurations

 

Step 4: Secure Engineering Collaboration Environments
