How can you secure communication between microservices?

Here are eight best practices for securing your microservices.

1. Use OAuth for user identity and access control.
2. Use ‘defence in depth’ to prioritize key services.
3. Don’t write your own crypto code.
4. Use automatic security updates.
5. Use a distributed firewall with centralized control.
6. Get your containers out of the public network.

How do I validate a JWT token in microservices?

Add the jsonwebtoken package to our gateway and microservices. Utilize FusionAuth’s HMAC default signing key to create signed JWTs for the gateway to pass to the microservices. Add roles to this JWT if the user is present. Decode that JWT in each of the microservices, using the same signing key, to verif the request.

How do I secure microservices with API gateway?

Microservice Security End-to-End flow

1. Authenticate the Oauth2 bearer token.
2. Authorize the request to the corresponding micro gateway based on the given scope.
3. Bridge the Oauth2 access token with relevant JWT by generate specific JWT token based on requested scope/audience and sign the payload.

How do I secure microservices in spring boot?

Microservices with Spring Boot — Authentication with JWT and Spring Security

1. Get the JWT based token from the authentication endpoint, eg /login.
2. Extract token from the authentication result.
3. Set the HTTP header as Authorization and value as Bearer jwt_token.
4. Then send a request to access the protected resources.

How does API gateway authentication work?

API Gateway supports multiple authentication methods that are suited to different applications and use cases. API Gateway uses the authentication method that you specify in your service configuration to validate incoming requests before passing them to your API backend.

Is JWT good for Microservices?

JWT too plays a key role in securing service-to-service communication. It can be used to carry the identity of the calling microservice, or the identity of the end user or the system that initiated the request. The JWT can also be used to propagate identity attributes between multiple trust domains.

What is API gateway in Microservices?

The API Gateway offers a reverse proxy to redirect or route requests (layer 7 routing, usually HTTP requests) to the endpoints of the internal microservices. The gateway provides a single endpoint or URL for the client apps and then internally maps the requests to a group of internal microservices.

Does API gateway handle authorization?

API gateway authentication is one of the key functions of an API gateway. In carrying out this function, the API gateway manages authentication and authorization for the entire group of APIs that sit behind it.

How do you handle security in Microservices?

Here are eight steps your teams can take to protect the integrity of your microservices architecture.

1. Make your microservices architecture secure by design.
2. Scan for dependencies.
3. Use HTTPS everywhere.
4. Use access and identity tokens.
5. Encrypt and protect secrets.
6. Slow down attackers.
7. Know your cloud and cluster security.
