• Own end-to-end remediation of database vulnerabilities across Oracle, SQL Server, Postgre
  
  SQL, and IBM Db2 platforms applying patches, configuration hardening fixes, and encryption updates within defined SLA windows.
• Triage database‑specific vulnerability findings from the vulnerability management platform, assess risk against asset criticality and business impact, and commit to remediation dates in the POAM.
• Identify false positives and risk acceptance candidates for database findings that cannot be remediated within standard SLA windows, preparing justification documentation for information security sign‑off.
• Coordinate with the centralized triage function to ensure database vulnerability records are accurately classified and routed before they reach the execution queue.

• Remediate database configuration vulnerabilities: default account removal, unnecessary privilege cleanup, weak authentication settings, insecure network listener configurations, and audit logging gaps across production and non‑production environments.
• Apply database encryption fixes, TLS on database connections, data‑at‑rest encryption gaps, and certificate rotation for database server communications.
• Maintain and update database security baseline standards across all supported platforms, ensuring configurations remain compliant with enterprise security policy following each remediation cycle.

• Remediate privilege escalation vulnerabilities at the database layer reviewing and revoking excessive DBA permissions, cleaning up orphaned database accounts, and enforcing least‑privilege access aligned to enterprise IAM standards.
• Own database credential rotation for service accounts and application database users flagged in vulnerability scans coordinating with the secrets management platform to ensure credentials are rotated within approved vault workflows without application disruption.
• Support quarterly database access reviews validating that application service accounts, DBA accounts, and shared credentials comply with least‑privilege standards and flagging violations for remediation.

• Prepare Method of Procedure documentation for all database‑level remediations that require change advisory board review detailing the fix approach, rollback plan, testing steps, and business impact assessment.
• Coordinate with application teams and platform teams to schedule database remediation deployments within approved change windows, ensuring downstream application connectivity and query performance are validated post‑remediation.
• Lead pre‑production database remediation testing validating that patches and configuration changes do not break application connectivity, stored procedures, or job scheduling before production deployment.

• Work closely with Java Developers, .NET Developers, and Middleware Admins in the App, Data and Middleware crew on vulnerabilities that span the application and database boundary: SQL injection remediations, JDBC connection pool vulnerabilities, and database‑driven application security fixes.
• Coordinate with the Container and TRC crew on Hikari DSP configuration propagation items that overlap with database connection management.
• Support the Sr. Security Engineer on access control and Cyber Ark credential management work at the database layer where the DBA owns the database‑side execution while the Security Engineer owns governance and vault integration design.

• Maintain accurate POAM records for all database vulnerability findings updating remediation status, dates, and closure confirmation in the vulnerability management platform following each fix deployment.
• Submit database vulnerability items for rescan after remediation is confirmed, validating that the CVE no longer appears before marking the POAM record closed.
• Contribute to weekly SLA burn‑down reporting providing database vulnerability status,…
