NIST 800-171 · CMMC 2.0 Level 2 · Since 2020
Taking the plant to CMMC 2.0 Level 2
I started our NIST 800-171 program around 2020, when the plant had a flat network and no security framework. Working with a security partner and our MSP, it took about three years to reach a Level 2 self-assessment, and I've run the program ever since.
- Ran weekly working sessions with the security partner and the MSP.
- Came in on weekends to test hardening changes without disrupting production.
- Rolled out network segmentation, 802.1X port authentication, and access control lists.
- Coordinated physical security: cameras and site access control.
- Wrote the policies the framework requires, revise them every year, and keep the SSP and POA&M current with the MSP.
Level 2 self-assessment complete and maintained, with access reviews, training, documentation, and audit evidence kept current. When a prime contractor asks about our cybersecurity posture, we answer with documented evidence.
