Understanding GraphQL Security: Protecting Your Server from Abuse
summary
Covers concrete defenses: disable introspection and field suggestions, enforce a query depth limit (e.g. 5–10), and implement per-field complexity costs (example name cost 1 currentLocation cost 100 with a 500 request cap) so parsers reject expensive queries before resolving. Turn unbounded lists into paginated connections, limit aliases and directives (or disable on mutations) to stop alias brute force and directive amplification, and use APM like Datadog plus libraries such as GraphQL Armor or Ruby graphql limits to monitor and enforce these protections.
