Database User Management & Security Hardening — Privilege Review

I will conduct a database user management review and implement security hardening — covering user account inventory, privilege mapping, superuser and administrative account review, application user privilege reduction to the minimum required (SELECT only where read-only access is sufficient, specific table permissions for application users), password policy enforcement, network host restriction for database connections, SSL/TLS encryption for client connections, and audit logging for privileged operations. Application database users with superuser or DBA privileges are a catastrophic security risk; a compromised application with superuser database access can drop all tables, exfiltrate all data, and create hidden backdoor accounts — none of which are possible with a correctly restricted application user.

The review covers all user accounts with their current grants, privilege reduction implementation, CREATE USER with host restriction, REVOKE statements for excessive privileges, password expiry policy configuration, SSL certificate setup for encrypted connections, and a user access matrix documenting the post-hardening privilege state.

This service suits any organisation preparing for security audit, compliance certification, or simply recognising that their database security posture has never been formally reviewed.
