API Not Reachable: Domain Fronting Unsuccessful
Steering API access can become complicated when domain fronting techniques are involved, particularly if your API management lacks stringent domain restrictions. Domain fronting allows requests to be rerouted through different domains, potentially bypassing your security measures and leading to unauthorized access. To combat this, you need to implement strict domain restrictions that validate incoming requests against a predefined list of allowed domains.
However, challenges often arise. Legitimate users may inadvertently trigger domain restrictions due to misconfigurations or reliance on services that utilize domain fronting. This can result in frustrating API access issues for users who aren't attempting to bypass security.
To address these challenges effectively, continuous monitoring and updating of your domain whitelists are essential.
Additionally, educating your users about the implications of domain restrictions is vital. Ensuring they understand how their API interactions might be affected by domain fronting can help minimize disruptions.
Domain API vs Experience API
Maneuvering the complexities of domain restrictions in APIs can be particularly challenging when dealing with Domain APIs and Experience APIs. Domain APIs focus on core business logic for backend services, while Experience APIs cater to specific consumer needs.
