Hardware

  • PXI Controller

Operating System

  • LabVIEW Real-Time (NI Linux Real-Time)

Issue Details

I need to harden my PXI controller to meet cybersecurity or government security requirements. I am looking for guidance on implementing a secure configuration similar to STIG (Security Technical Implementation Guides) hardening requirements.

Solution

For NI Linux Real-Time systems, use the SNAC utility to place the system into the most secure supported configuration.
  • Download the SNAC utility from the GitHub release page:
    NI Linux Real-Time SNAC Guide Releases
  • Review the documentation included with the utility.
  • Apply the SNAC configuration to the PXI controller according to the provided instructions.
  • Validate the resulting system configuration against the cybersecurity requirements for the deployment environment.

Additional Information

The SNAC utility is commonly used by customers as an alternative to a STIG implementation for NI Linux Real-Time deployments.
