Database security: securing SQL Server, MySQL and PostgreSQL
Database Security for SQL Server, MySQL and PostgreSQL: hardening, least privilege, audit logging, encryption and SQL injection protection.
Summary: GraphQL APIs pose specific security risks: introspection exposes the entire API structure, deeply nested queries can cause denial-of-service attacks (query depth attacks), batching allows rate limits to be bypassed, and a lack of field-level authorization leads to data leaks. Protection: Disable introspection in production, set query depth limits, implement field-level authorization, and enforce query complexity limits.
