Organizations that want to create a chatbot often turn to Dialogflow, Google Cloud’s service for creating conversational agents that can understand and respond to natural language. Available in two editions, many organizations choose Dialogflow CX for its advanced chatbot capabilities. However, integrating a chatbot with your website in the absence of a middleware solution may risk directly injecting sensitive credentials like service account keys into the frontend, or opting for unauthenticated URLs. This is not a best practice for production-grade systems and can result in exposing your agent and Google project ID, leaving them vulnerable.
You can mitigate this by introducing an Apigee layer between your frontend and DialogFlow CX APIs. Apigee is a full lifecycle API management platform offered by Google Cloud that enables businesses to design, secure, publish, analyze, monitor, and monetize their APIs. Apigee acts as a robust layer between backend services and clients that access them, providing a multitude of features and benefits. In this context, Apigee provides:
-
Centralized authentication and authorization: Apigee acts as a secure gateway, handling all authentication and authorization processes. This eliminates the need to expose credentials on the frontend.
-
Controlled access: Apigee allows you to define fine-grained access policies, determining which frontend components can interact with specific DialogFlow CX APIs.
-
API key management: Apigee helps manage API keys, simplifying the process of rotation and revocation if a compromise occurs.
-
Threat protection: Apigee offers built-in features like rate limiting, quota management, and spike arrest, safeguarding your APIs from abuse and potential attacks.
By using Apigee as an intermediary, you not only enhance the security of your chatbot integration but also gain a powerful tool for managing and monitoring your APIs. In this post we’ll walk you through how to configure Apigee to improve security for conversational agents.
