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.

How does https authentication works in microservices?

Through mutual SSL, mutual authentication between microservices can be achieved, and data transmission between microservices can be encrypted through TLS. A certificate needs to be generated for each microservice, and the microservices are authenticated with each other’s certificates.

How do you control user identity within microservices?

What is usually done is as follows:

1. The Reference Token is issued by the Authorization Server. The client sends back when it’s time to call the API.
2. In the middle: The Authorization Server validates the token and responds with a JWT.
3. The JWT is then passed further along in the network.

How do you handle rollback in microservices?

How to rollback MicroServices

1. Step-1: M1 making a call to M2 to update some user data in MySQL and it updated successfully then finally it got success response from M2.
2. Step-2: M1 making a call to M3 to update some data in Cassandra and it updated successfully then finally it got success response from M3.

When to go for microservices authentication and authorization?

If your back-end (micro) services are to have total faith that the front-end (global) services have authenticated and authorized the transaction, then you can go for option 1.

How is an authentication token generated in a microservice?

This is usually done by giving a token generated by the authentication process, or something like that. The AuthBearer does both. First, it creates a token when the user asks it to; and, when the microservices give it a token, it checks for authorization.

Which is the best way to do authentication?

This approach is likely the best fit for most people. Keep the clunky authentication layer at your front-end global services layer. Then, when the front-end calls the back-end microservices to do an actual job, it can provide a security context.

How are authentication libraries used in microservices architecture?

Authentication should be a global solution and handle as a cross-cutting concern. One option to refine this solution would be to use a shared authentication library loaded on each microservice. This will prevent code duplication, and the development team will focus only on their business domain.
