Aerospace suppliers are often held to security expectations driven by customer requirements, contract clauses, and the type of data handled, not just company size. If your environment includes sensitive engineering drawings or controlled customer data, you’ll typically need a baseline set of controls plus the documentation to prove them. For many small-to-mid suppliers, a practical readiness plan is phased over 6–12 months, starting with MFA, access control, monitoring, and restore-tested backups.
Step 1: Identify What Data You Handle (And Where It Lives)
Requirements scale with data sensitivity. Start by mapping where sensitive data lives:
- CAD/PDM repositories
- Email attachments and shared mailboxes
- File shares and cloud drives
- ERP systems (customer/pricing/BOM data)
Step 2: Confirm Customer / Contract Expectations
Many requirements “flow down” from primes and customer security programs.
What to look for:
- Security questionnaires and minimum control expectations
- Incident reporting expectations
- Proof requests (MFA evidence, restore logs, diagrams)
Step 3: Implement the Baseline Control Set (Most Commonly Requested)
- Strong Identity Security
-
- MFA for all users (especially email)
- Admin accounts separated from daily-use accounts
- Least privilege access
- Systems Management Discipline
- Patch management on a monthly cadence
- Asset inventory (know what you have)
- Monitoring & Detection
-
- Endpoint + server protection
- Central alerting/log review (managed monitoring at minimum)
- Backup & Recovery Readiness
-
- Immutable/offsite backups
- Restore tests on a schedule (monthly spot checks + quarterly full tests)
- Vendor Access Control
-
- Vendor access restricted, time-bound, and logged
- No shared vendor credentials
Step 4: Build the “Proof Pack” (Evidence Matters)
Even strong controls can fail a review if you can’t show proof.
A simple proof pack often includes:
- Asset inventory + network diagram
- MFA enforcement evidence/policy
- Backup restore test logs
- Incident response plan
- Security awareness training records
Step 5: Make It Operational (So Security Doesn’t Break Production)
Security must support uptime:
-
- Separate production and office networks
- Restrict access to engineering shares
- Define recovery targets for ERP and CAD
Illustrative Scenario: Creating an Aerospace Customer “Proof Pack” Before Review
A 60-employee aerospace supplier in Los Angeles discovered controlled data in shared drives and email archives. There was no formal evidence package, and backups had never been restored.
After a structured program:
- Data was scoped into a controlled enclave
- MFA and access restrictions were enforced
- Restore testing was scheduled quarterly
- A proof pack was created for customer/security reviews
Result: reduced contract risk and fewer “fire drill” requests from primes.
Trust Signals
Look for a partner who can:
- Secure CAD/PDM and engineering repositories
- Align controls to customer requirements
- Produce evidence (diagrams, policies, restore logs)
- Implement changes without disrupting production
Run an Aerospace Cyber Readiness Check (FCI/CUI Focused)
Aerospace supplier requirements are easier when you scope what you handle, implement baseline controls, and build evidence as you go—before a prime contractor or renewal deadline forces a scramble.
Book a 30-minute call with Fothion today and we’ll:
- clarify whether you’re handling FCI/CUI (and where it lives)
- identify your top 5 control gaps (MFA, access, monitoring, backups, vendor access)
- outline a practical 6–12 month plan + “proof pack” you can reuse for reviews
