Security basics
In microservice development, security is one of the critical challenges that affects the ways you store, process, and transmit data over the system. A breach in one service might compromise the entire system, making it vulnerable to various risks and attacks. Therefore, security should be seen as one of the critical aspects of service development from the very early phases of the service life cycle.
In this section, we are going to review the key areas of software security that apply to microservice development and demonstrate how to apply them to the services we created in the previous chapters.
Key areas of software security
First, we need to define a list of some of the key areas of software security that apply to microservices:
- Authentication: Verifying the identities of system users or services
- Access control: Defining and enforcing access permissions
- Data security: Encrypting data that is stored in the system (data at rest)...
