How do you securely communicate between microservices?
Here are eight best practices for securing your microservices.
- Use OAuth for user identity and access control.
- Use ‘defence in depth’ to prioritize key services.
- Don’t write your own crypto code.
- Use automatic security updates.
- Use a distributed firewall with centralized control.
- Get your containers out of the public network.
How you can secure communication between microservices with mutual authentication?
In mTLS, each microservice in a service mesh verifies the other’s certificate and uses the public keys to create encryption keys unique to each conversation. This enables the communications between pairs of microservices to be authenticated and encrypted.
How does Netflix handle authentication?
User enters their credentials and the Netflix client transmits the credentials, along with the ESN of the device to the Edge gateway, AKA Zuul. Zuul redirects the user call to the API /login endpoint. The API server orchestrates backend systems to authenticate the user.
Why is Netflix taking money out of my account?
Your bank may have updated your credit or debit card information. Some banks automatically update credit or debit card information when a new card is issued. In some cases, your bank may also allow recurring charges to continue. You can update your payment information or cancel the account from your Account page.
Why does Netflix have so many microservices?
By adopting microservices, Netflix engineers easily change any services which lead to faster deployments. More importantly, they can track the performance of each service and quickly isolate its issues from other running services.
What do you mean by distributed tracing in microservices?
distributed request tracing
Distributed tracing, sometimes called distributed request tracing, is a method to monitor applications built on a microservices architecture. This allows them to pinpoint bottlenecks, bugs, and other issues that impact the application’s performance.
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.
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 to control user identity within microservices?
There is a method that allows one to combine the benefits of isolated deployment with the ease of a federated identity. Jacob Ideskog of Curity believes that to accomplish this OAuth should be interpreted not as Authentication, and not as Authorization, but as Delegation.
How is session storage handled in microservice authentication strategy?
In this strategy, session storage doesn’t really matter, as it is only handled by the authenticating app. Then the user_id can be forwarded to other services. I thought of Rails + Devise (+ Redis or mem-cached, or cookie storage, etc.) but there are tons of possibilities.
