## Recommendations
- **Implement Multi-Factor Authentication (MFA):** Ensure all staff and administrative accounts require MFA to prevent easy initial access.
- **Endpoint Detection and Response (EDR):** Deploy EDR solutions across the district network to catch unauthorized lateral movement in real-time.
- **User Awareness Training:** Conduct phishing simulations for district employees to mitigate common entry vectors.
- **Offline Backups:** Ensure critical student and administrative data is backed up in an immutable or offline format to defend against potential ransomware.
