In the age of LGPD, data protection is no longer just a legal concern — it has become a business strategy. And who’s on the front lines of this challenge? The DBA. In this article, HTI Tecnologia specialists explain the responsibilities of database professionals in managing sensitive data and why outsourcing DBA services brings security, compliance, and cost-efficiency.
What the LGPD Requires from DBAs
The General Data Protection Law imposes strict rules on the collection, storage, and processing of personal data. For SQL and NoSQL databases, this means:
- Inventory and classification of sensitive data
- Implementation of access controls, encryption at rest and in transit
- Logging and audit trails
- Continuous monitoring for data leaks or unauthorized access
- Rapid response to incidents and communication with the Brazilian Data Protection Authority (ANPD)
- Ensuring data subject rights, such as anonymization and portability
For a DBA, this is far beyond performance tuning — it involves certifying standards, reviewing schemas, and applying granular encryption to critical data columns, for example. A DBA’s proactive role is essential for General Data Protection Law compliance.
Direct Responsibilities of the DBA
1. Data Mapping
- Identify and catalog personal and sensitive data across databases (MySQL, PostgreSQL, Oracle, MongoDB, etc.)
- Add metadata annotations indicating who can access what data and for what purpose
- Collaborate with legal and compliance teams to ensure correct classification of data under LGPD
2. Access Control and Privileges
- Enforce least privilege access
- Separate technical and administrative access roles
- Regularly review permissions and users according to LGPD guidelines
- Apply multi-factor authentication and geographical restrictions to critical systems
3. Encryption
- Apply field-level encryption to sensitive data
- Enable encryption at rest and in transit in major DBMS platforms
- Manage encryption keys securely and according to LGPD standards
- Rotate keys periodically based on security policies
4. Logging and Auditing
- Enable and manage audit logs to track changes and access
- Generate auditable reports for regulatory inspections or incidents
- Be ready to provide complete audit trails for investigations
- Integrate with SIEM (Security Information and Event Management) systems
5. Backup and Data Retention
- Ensure backups are encrypted
- Define and enforce data retention policies based on LGPD timeframes
- Implement secure deletion routines for expired data
- Store backups in secure, access-controlled, and geo-replicated environments
6. Leak Prevention
- Set up monitoring and DLP (Data Loss Prevention) tools
- Detect suspicious or anomalous access patterns
- Implement controls to prevent data export from unauthorized environments
- Create LGPD-specific incident response playbooks
