A structured framework categorizing various authentication methods used for Non-Human Identities.
Description
The Authentication Methods Hierarchy refers to a systematic arrangement of different authentication techniques that can be employed to verify the identities of Non-Human Identities (NHIs), such as applications, devices, and services. In the context of NHIs, authentication is crucial for ensuring secure communication and operations within digital ecosystems. The hierarchy typically categorizes methods based on their strength, complexity, and usability. At the base of the hierarchy, simpler methods like API keys or static passwords can be found, while more sophisticated techniques like OAuth tokens, digital certificates, and biometric authentication are positioned higher due to their enhanced security features. The hierarchy aids organizations in selecting the appropriate authentication method based on the sensitivity of the operations performed by the NHI and the potential risks involved. By implementing a suitable authentication method, organizations can protect their systems from unauthorized access, ensuring the integrity and confidentiality of their data.
Examples
- API keys for basic application authentication
- OAuth 2.0 tokens for secure access delegation
Additional Information
- Higher levels of the hierarchy often require multi-factor authentication.
- The choice of authentication method can impact user experience and system performance.
