GraphQL API Security
Address specific security challenges in GraphQL APIs, such as query depth limiting, complexity analysis, and proper authorization.
GraphQL's Security Landscape
GraphQL APIs offer incredible flexibility, allowing clients to request exactly the data they need. However, this power introduces unique security challenges that differ from traditional REST APIs.
In this lesson, we'll explore how to protect your GraphQL backend from common vulnerabilities, ensuring both performance and data integrity.
Flexible Queries, New Risks
Unlike REST, where endpoints define fixed data structures, GraphQL lets clients build custom queries. While efficient, this flexibility can be misused:
- Excessive Depth: A malicious query might request deeply nested data, potentially leading to server overload.
- Complex Operations: Some queries might involve expensive database joins or computations that can degrade performance.
We need specific strategies to manage this flexibility securely.
