Security-focused and reliability-oriented validation of APIs, including authentication, authorization, input handling, error behavior, resilience and misuse scenarios.
APIs often expose critical business capabilities and sensitive data. Security and reliability testing adds another layer of confidence by examining how interfaces behave when requests are unauthorized, malformed, unexpected or repeated under challenging conditions.
HNI can incorporate security-oriented scenarios into broader API testing programs, helping teams identify weaknesses in access control, input handling and error behavior.
Validate that protected APIs require the expected identity and authentication conditions.
Check that users and service identities can access only the resources and actions permitted to them.
Exercise invalid, unexpected and boundary inputs to assess validation and error behavior.
Review error responses for appropriate messaging and avoidance of unnecessary technical information.
Evaluate behavior during dependency failures, timeouts and other abnormal operating conditions.
Repeat critical security and reliability scenarios after changes to maintain confidence over time.
