Challenge
Ensuring that classified networks remain up to date with the latest Microsoft security patches presents a significant challenge. These networks are air-gapped and cannot connect to unclassified networks, making traditional update distribution methods impractical. Manual updates introduce inefficiencies and potential security risks prone to human error.
Solution
The Fox WSUS Replicator, in combination with the Fox DataDiode, provides a secure, automated method to transfer Windows updates from a public (black) network to an internal (red) network. By leveraging a one-way data transfer mechanism, updates are safely transmitted without introducing attack vectors or requiring direct internet access. The scheduling functionality ensures updates are transferred at predefined intervals, maintaining network security while minimizing administrative overhead.
Results
The implementation of DataDiode and Fox WSUS Replicator yielded significant results:
- Automated Windows updates: in classified networks without manual intervention.
- No direct internet exposure: eliminating external attack risks.
- Seamless compliance: with security regulations such as NIS2 and certifications like Common Criteria.
- Reduced operational burden: ensuring updates are applied efficiently and securely.
