## Lessons Learned
- **Key takeaways:** Administrative/non-clinical staff often possess broad access to sensitive datasets without sufficient technical barriers to export that data.
- **What could have been done better:** Implementation of Data Loss Prevention (DLP) software could have automatically blocked the transmission of NHS numbers or large spreadsheets to external domains.
## Recommendations
- **Strict Data Loss Prevention (DLP):** Implement policies to block the emailing of PII/PHI to external or personal domains.
- **Data Anonymization:** Ensure that data used for "analytical purposes" is pseudonymized or anonymized before being extracted from secure systems.
- **Role-Based Access Control (RBAC):** Review and tighten access to maternity systems to ensure only the minimum necessary data is accessible.
- **User Education:** Re-train staff on the "Caldicott Principles" and the legal ramifications of transferring data to personal accounts.
