- **What could have been done better:** Enhanced oversight and automated compliance checks could have identified the unpatched system before it was exploited.
## Recommendations
- **Third-Party Risk Management (TPRM):** Implement stricter Service Level Agreements (SLAs) regarding patch management timelines for contractors.
- **Vulnerability Management:** Deploy automated vulnerability scanning tools to verify that contractors are maintaining systems according to agency standards.
- **Zero Trust Architecture:** Ensure that even if one system is unpatched, strict segmentation prevents access to sensitive employee databases.
