Action to mitigate Security vulnerabilities

[sandeephs1]

Dear Data All,

We have identified certain actions/recommendations to mitigate security vulnerabilities.
Appreciate your response to implement/action these recommendations -

• Restrict the number of directives allowed per query to prevent excessive processing overhead.

• Set limits on query depth and complexity using libraries like graphql-query-complexity to prevent deeply nested or computationally expensive queries.

• Apply rate limits at the API gateway or GraphQL layer to restrict the number of queries per user or IP.

• Define maximum execution time for queries to prevent long-running directive-heavy requests from exhausting resources.

• Use schema validation and input filtering to reject malformed or excessively complex queries before execution.

• Track query execution metrics to detect and block abusive patterns early.

• Optimize query execution with caching mechanisms and batch processing to reduce load from repeated directive-based queries.

• Alias Limitations: Restrict the number of unique aliases allowed per query to reduce redundant processing.

• Query Complexity and Depth Limits: Set limits on query complexity and maximum depth to prevent high-cost queries.

• Rate Limiting and Authentication: Enforce rate limiting and, where appropriate, require authentication to restrict access and frequency of requests.

• Server-Side Query Analysis: Use tools or middleware to analyze and reject queries with excessive aliases or complexity.
