Database Security and Access Control

Design comprehensive database audit logging strategies for SQL Server, Oracle Unified Auditing, PostgreSQL pgaudit, and MySQL to meet compliance and forensic requirements.

Expert guidance on TDE, column-level encryption, key management, and encryption-at-rest strategies for SQL Server, Oracle, PostgreSQL, and cloud databases.

Configure database firewalls, network-layer access controls, and allowlist policies to restrict unauthorized connections and detect anomalous database traffic patterns.

Audit database user privileges, detect excessive permissions, and enforce least-privilege principles across Oracle, SQL Server, PostgreSQL, and MySQL environments.

Design scalable RBAC role hierarchies for database environments, structuring grants, inheritance, and separation of duties across Oracle, SQL Server, and PostgreSQL.

Eliminate hardcoded database credentials using HashiCorp Vault, AWS Secrets Manager, and Azure Key Vault. Design dynamic secret rotation and secure credential injection pipelines.

Harden database service accounts used by applications and automation: enforce least privilege, isolate accounts per service, and eliminate shared credentials in production environments.

Implement GDPR-compliant data access controls, right-to-erasure workflows, data minimization strategies, and pseudonymization at the database level for EU personal data.

Design and implement row-level security policies in PostgreSQL, SQL Server, Oracle VPD, and BigQuery to enforce fine-grained data access control based on user context.

Identify SQL injection vulnerabilities in database-facing code, review parameterization practices, and implement defense-in-depth strategies for secure database access layers.
