How can you secure communication between microservices?
8 Ways to Secure Your Microservices Architecture
- Make your microservices architecture secure by design.
- Find dependencies.
- Use HTTPS everywhere.
- Use identity and access tokens.
- Encrypt and protect secrets.
- Slow down the attackers.
- Know the security of your cloud and cluster.
- Cover your security bases.

How is communication between microservices authenticated?
You can make communication between microservices secure by at least following two methodologies: JWt Token: Suppose microservice A wants to communicate with microservice B, then the token issued by A and the audience of the token is B. In that case, the token it is signed by microservice A with its private key.
How do I share a JWT token between microservices?
Add the jsonwebtoken package to our gateway and microservices. Use the default FusionAuth HMAC 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 verify the request.
How are sessions managed in microservices?
A different approach to authentication and session management is needed to ensure a scalable architecture.
- Authentication of microservice requests.
- Distributed session management in microservices.
- Session tokens with an API Gateway.
- OAuth and authentication with third-party applications.
How do you handle rollback in microservices?
How to reverse Microservices
- Step 1: M1 made a call to M2 to update some user data in MySQL and it was successfully updated and finally got a successful response from M2.
- Step 2: M1 made a call to M3 to update some data in Cassandra and it updated successfully and finally got a successful response from M3.
What does JWT mean in microservices architecture?
Here we will discuss a JWT-based method to secure communication between microservices. JWT stands for JSON Web Token. It exists in the form of JWS (JSON Web Signature) or JWE (JSON Web Encryption). JWS and JWE are concrete implementations of JWT, which is like an abstract class.
Where does the JWT token go in a microservice?
The request along with the access token is sent to API Gateway. At this point, the access token is decrypted and sent back to the authorization server to get the JWT (after validation). The JWT token contains the identity of the user along with the microservices.
How are JWTs signed in Spring Boot microservices?
The token issuer applies signing and encryption as follows: the token issuer signs the token with its private key and creates JWS (JWT: signed). The token issuer encrypts the JWS with the service provider’s public key. The encrypted JWS is called JWE (JWT – encrypted).
How to ensure communication between services in a microservices architecture?
There are a couple of ways to secure communication between services in a microservices architecture. Adopt the authentication proxy pattern, or pass the jwt as the services call each other; Regardless of what you choose, each service must address the security layer.
