What is different about IT for aerospace and defense

Defense suppliers inherit their customer's security posture whether or not they feel ready for it, and losing a certification means losing the contract. Controlled unclassified information has to be identified before it can be protected.

Compliance that actually bites

CMMC and NIST 800-171 are contractual conditions rather than aspirations, with ITAR and EAR export controls on technical data and DFARS clauses flowed down through the supply chain.

Questions worth asking a provider

  • Have you taken a supplier through a CMMC assessment, and what level?
  • How do you identify and segregate controlled unclassified information?
  • Are your own staff and infrastructure compliant with ITAR requirements?
