Security and Authentication in Thanos
Overview
Thanos is an open-source system for collecting, processing, and serving time series data. It includes several components, such as the Thanos Query API server, the Thanos Sidecar, and the Thanos Ruler. Thanos provides various security protocols and strategies to ensure the confidentiality, integrity, and availability of the data.
Security Protocols and Strategies
Authentication
Thanos does not have built-in support for authentication. However, it can be integrated with external authentication systems like OAuth2 or JWT through the use of middleware or reverse proxies.
Authorization
Thanos does not have built-in support for authorization. Access control can be implemented using external systems like RBAC or ABAC in combination with the Thanos components.
Encryption
Thanos does not encrypt metrics in local storage or on disk. It is recommended to set server-side encryption for object storage, such as AWS S3 or Google Cloud Storage.
TLS
Thanos supports Transport Layer Security (TLS) for secure communication between components. The Thanos Query API server and the Thanos Sidecar both support TLS.
Best Practices
To ensure the security of your Thanos deployment, follow these best practices:
- Use strong, unique passwords for all user accounts.
- Keep your Thanos components up-to-date with the latest security patches.
- Use a firewall to restrict access to your Thanos components.
- Implement access control using external systems.
- Encrypt data at rest using server-side encryption.
- Use TLS for secure communication between components.
