A San Diego story
The Tuesday the SPRS score turned out to be a guess
the owner of a 28-person machine shop on Miramar Road that supplies a Poway prime
It is a Tuesday in May, marine layer still hanging over Miramar Road at noon, and the owner of a 28-person machine shop is reading an email from his biggest customer's supplier-quality manager. Send us your current NIST 800-171 score and your system security plan by Friday, it says, or the next purchase order goes to a shop that can. The prime is in Poway. The parts are for a Navy program.
The owner entered a score two years ago, from memory, on a Sunday. He starts walking the shop to see how true it was. The drawings marked CUI sit on a shared drive that the front office, the floor and the old cloud-sync account can all reach. The CAM workstation has not been updated since it was installed.
Then he talks to his estimator, a good man who has quoted jobs for him for nine years. The estimator explains, without a trace of guilt, that he has been emailing the drawings to his personal account for two years so he can quote from home in Escondido.
The owner opens that personal account with him and finds it was signed into last month from a city neither of them can find on a map.
What changes the ending
- CUI kept in one controlled place, marked, with sync accounts and personal email cut off from it, so a drawing cannot wander home (CIS 3 Data Protection)
- Access by role, multi-factor authentication on the shared drive and the remote tools, and a quarterly review of who can reach the Navy work (CIS 6 Access Control Management)
- Quoting from home solved the right way, with a company laptop and a secure connection, and staff trained on why the marking on the drawing decides the shop's next PO (CIS 14 Security Awareness and Skills Training)
