How do you handle authorization in microservices?

Handling application-specific authorization in the microservices. A better solution would be to make the microservices responsible for handling authorization. The API gateway should pass the JWT along with the request towards the microservice. As explained before, the JWT will contain the roles assigned to the user.

How do you handle security in microservices based application?

8 Ways to Secure 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.
8. Cover your security bases.

Which is the best suited authorization mechanism in microservices?

JSON Web Tokens: overwhelming advantages ared to SAML applications. JSON Web Tokens thus appear to be the most appropriate option for user authentication in microservices environments. More information on JSON Web Tokens can be found at http://jwt.io and in RFC 7519.

How do clients access services in Microservices architecture?

The API Gateway pattern defines how clients access the services in a microservice architecture. The Client-side Discovery and Server-side Discovery patterns are used to route requests for a client to an available service instance in a microservice architecture.

How is authorization implemented?

Authorization is implemented using access tokens that must be set. A user, or the groups to which the user belongs to, can be associated with zero-to-many access token values. The access token values are set on the DWLControl object so that the values are accessible during the transaction.

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 does security work in microservices?

Microservices Architecture Best Practices for Security Some fundamental tenets for all designs are: Encrypt all communications (using https or transport layer security). Authenticate all access requests. Do not hard code certificates, passwords or any form of secrets within the code.

How do you perform security testing of microservices?

Test each microservice to see if it works on its own. Then test the communication between these microservices. Each microservice needs to be individually functional and the communication between microservices via APIs needs to be tested also.

How do you handle asynchronous communication in Microservices?

Microservices that communicate in an asynchronous manner can use a protocol such as AMQP to exchange messages via a message broker. The intended service receives the message in its own time. The sending service is not locked to the broker. It simply fires and forgets.

How do you handle asynchronous calls in Microservices?

You might use any protocol to communicate and propagate data asynchronously across microservices in order to have eventual consistency. As mentioned, you could use integration events using an event bus or message broker or you could even use HTTP by polling the other services instead.

How do you handle API authentication?

6 Answers

1. Create a Login/logout API like: /api/v1/login and api/v1/logout.
2. In these Login and Logout APIs, perform the authentication with your user store.
3. The outcome is a token (usually, JSESSIONID ) that is sent back to the client (web, mobile, whatever)
