and Authorization
Motivation
Protecting sensitive data when events are handled is crucial. This section outlines the and authorization mechanisms implemented in the go-events library.
Approach
The go-events library leverages a combination of and authorization techniques to ensure secure event handling. This approach involves:
- Authentication: Verifying the identity of the event source to ensure it is trusted.
- Authorization: Determining the permissions of the event source to access specific resources or perform actions.
Authentication
1. Token-based Authentication:
The go-events library supports token-based authentication using JWT (JSON Web Tokens). Events are authenticated using a JWT token that is validated against a configured key.
Example:
// ...
// Set JWT secret key
config.JWTSecret = "your-secret-key"
// ...
Source: config.go
2. Certificate-based Authentication:
The library also supports certificate-based authentication, where events are authenticated based on the certificate presented by the event source. This approach is particularly useful for securing communication between services within a cluster.
Example:
// ...
// Set TLS certificate file path
config.TLSConfig.CertFile = "/path/to/cert.pem"
// ...
Source: config.go
3. API Key Authentication:
For simpler authentication scenarios, go-events supports API key authentication. Events are authenticated using a pre-configured API key.
Example:
// ...
// Set API key
config.APIKey = "your-api-key"
// ...
Source: config.go
Authorization
1. Role-based Access Control (RBAC):
go-events utilizes RBAC for fine-grained authorization. Events are authorized based on the roles assigned to the event source.
Example:
// ...
// Define roles and permissions
roles := map[string][]string{
"admin": {"read", "write", "delete"},
"user": {"read"},
}
// ...
Source: auth.go
2. Policy-based Authorization:
The library supports policy-based authorization, where custom policies define the allowed actions for events. This offers flexibility for implementing specific authorization rules.
Example:
// ...
// Define custom authorization policies
policies := []string{
"event.type == 'create' && event.resource == 'users' && event.source.role == 'admin'",
}
// ...
Source: auth.go
Best Practices
- Choose the authentication and authorization methods that best suit your security requirements.
- Regularly rotate your secrets (e.g., JWT secret keys, API keys).
- Implement robust error handling and logging for security incidents.
Conclusion
The go-events library provides a comprehensive set of and authorization mechanisms to ensure secure event handling. By properly configuring authentication and authorization, you can protect sensitive data and ensure that only authorized entities can access and manipulate events.
