+---
+
+[HITRUST CSF](https://hitrustalliance.net/) (Common Security Framework) is a widely adopted security framework in healthcare and other regulated industries. For organizations already familiar with HIPAA, the relationship is straightforward:
+
+- HIPAA defines **what** must be protected — electronic Protected Health Information (ePHI) — but leaves the implementation details vague.
+- HITRUST provides the **how** — prescriptive, certifiable controls that satisfy HIPAA requirements and give organizations clear implementation guidance.
+
+Since databases are the primary storage for sensitive health data, database operations are a critical area for HITRUST compliance. This post covers the key database controls, associated risks, and how to implement them effectively.
+
+## Access Control
+
+Only authorized users should access sensitive data, with verifiable identity and appropriate privileges. This is foundational to HITRUST compliance.
+
+**Key controls:**
+
+- **Role-Based Access Control (RBAC)** — Assign permissions based on job function rather than individual users. Clinical staff access patient records; billing staff access financial data; DBAs manage infrastructure.
+- **Least Privilege** — Grant the minimum access needed for each task. A developer debugging an issue doesn't need write access to production.
+- **Just-in-Time Access** — Provide temporary elevated access that automatically expires. This reduces the window of exposure for privileged operations.
+- **Authentication** — Verify user identity through MFA, SSO, and LDAP/AD integration. Shared credentials make accountability impossible.
+
+**Risks without these controls:**
+
+- Unauthorized access to ePHI
+- Over-privileged accounts creating unnecessary exposure
+- No accountability when incidents occur
+
+## Audit Logging
+
+All access and changes to sensitive data must be recorded, centralized, and analyzable. Audit trails are essential for compliance investigations, certification assessments, and real-time threat detection.
+
+**Key controls:**
+
+- **Query logging** — Track who accessed what data and when. This provides the evidence trail auditors require.
+- **Change tracking** — Record all DDL and DML operations with before/after states. Know exactly what changed and who made the change.
+- **Log retention** — Maintain audit trails for the required retention period (6+ years for HIPAA-related compliance).
+- **SIEM integration** — Stream database audit logs to your SIEM (Security Information and Event Management) system. Correlate database activity with other security events for unified threat detection and incident response.
+
+**Risks without these controls:**
+
+- Unable to investigate breaches or demonstrate compliance
+- No accountability for data access or modifications
+- Database activity siloed from broader security monitoring
+- Gaps in audit trails causing certification failures
+
+## Change Management
+
+Database changes must be controlled, reviewed, and traceable. Uncontrolled changes are a common source of both security incidents and compliance failures.
+
+**Key controls:**
+
+- **Approval workflows** — Require review and approval before changes reach production. No direct production access without oversight.
+- **Risk-based classification** — Apply different approval paths based on change risk. A column rename needs less scrutiny than dropping a table.
+- **Rollback capability** — Maintain the ability to revert changes when issues arise. This reduces the blast radius of mistakes.
+- **Change history** — Keep a complete record of what changed, who approved it, and why. This is critical for audit evidence.
+
+**Risks without these controls:**
+
+- Unreviewed changes introducing vulnerabilities or breaking compliance
+- No ability to trace when or how data was altered
+- Emergency changes bypassing security controls with no oversight
+
+## Data Protection
+
+Sensitive data must be protected from unauthorized disclosure, both at rest and during access.
+
+**Key controls:**
+
+- **Data masking** — Hide sensitive fields like SSN, diagnosis codes, or payment information from users who don't need full access. A support engineer troubleshooting can see order status without seeing payment details.
+- **Data classification** — Identify and label sensitive data to apply appropriate controls. You can't protect what you haven't identified.
+- **Encryption** — Protect data at rest and in transit. This is table stakes for any compliance framework.
+- **Secret management** — Secure handling of database credentials and connection strings. Credentials in code or logs are a common breach vector.
+
+**Risks without these controls:**
+
+- Sensitive data exposed to users who only need partial access
+- No visibility into where sensitive data resides across your databases
+- Credentials leaked through code repositories or application logs
