How do you provide security between microservices?
Here are eight steps your teams can take to protect the integrity of your microservices architecture.
- Make your microservices architecture secure by design.
- Scan for dependencies.
- Use HTTPS everywhere.
- Use access and identity tokens.
- Encrypt and protect secrets.
- Slow down attackers.
- Know your cloud and cluster security.
How does authentication work in a microservice service?
It’s often necessary for resources and APIs published by a service to be limited to certain trusted users or clients. The first step to making these sorts of API-level trust decisions is authentication. Authentication is the process of reliably verifying a user’s identity. In microservice scenarios, authentication is typically handled centrally.
How is Azure Active Directory used in microservices?
When the API Gateway centralizes authentication, it adds user information when forwarding requests to the microservices. If services can be accessed directly, an authentication service like Azure Active Directory or a dedicated authentication microservice acting as a security token service (STS) can be used to authenticate users.
Why is interservice communication important in microservices architecture?
Responsiveness. An upstream service can reply faster if it does not wait on downstream services. This is especially useful in a microservices architecture. If there is a chain of service dependencies (service A calls B, which calls C, and so on), waiting on synchronous calls can add unacceptable amounts of latency.
What do you mean by authorization in microservices architecture?
Authorization is the process of verifying if the authenticated user is authorized to access specific information or be allowed to execute a certain operation. This process determines which permissions the user has.
