This summary highlights the importance of securing a GraphQL API from malicious queries. The article discusses how GraphQL's flexibility can be both an advantage and a security risk, as it allows for complex and nested queries that can overload servers and databases. To mitigate this, three main protection methods are presented: Size Limiting, Query Whitelisting, and Depth Limiting. While these methods have trade-offs, they provide a good starting point for securing a GraphQL API. Additionally, the article introduces Query Cost Analysis as an advanced method that can provide full coverage against malicious actors, but requires more work to implement. The recommended approach is to use Depth and Amount Limiting as the minimum protection, with Query Cost Analysis being considered for more complex scenarios.
