## Lessons Learned
- **Key takeaways:** Reliance on a single, dominant system integrator (LANIT) creates a critical single point of failure and significant supply chain risk for national infrastructure, including defense and finance.
- **What could have been done better:** Insufficient internal security or segmentation within the service provider allowed the compromise to reach a scope affecting high-security clients.
## Recommendations
- Implement mandatory and frequent rotation of service/vendor access credentials, especially those granted to third-party IT support/integrators.
- Strictly enforce the principle of least privilege for remote access granted to managed service providers.
- Organizations using LANIT software/infrastructure should verify existing supply chain security auditing logs.
- Enhance monitoring specifically focused on activities originating from or traversing network segments associated with trusted external vendors.
