Node Attestation

IAM Concepts
Node attestation is the process by which a SPIRE server verifies the identity and integrity of a node (physical machine, VM, or Kubernetes node) before allowing the SPIRE agent running on it to request SVIDs for workloads. It uses platform-specific mechanisms such as cloud provider instance identity documents or TPM measurements to establish trust in the underlying infrastructure before any workload identity is issued on top of it.

No-Code Auth

IAM Concepts
No-code auth is an authentication approach where application code does not directly implement authentication logic or manage credentials. Instead, infrastructure components such as service meshes, proxies or authentication agents handle identity verification, credential injection and policy enforcement transparently at runtime.

Non-Human Identity

Identity Types
A non-human identity (NHI) is a digital identity assigned to a software-based entity, such as an application, service, workload, API, and AI agent, that needs to authenticate and access resources autonomously. It functions much like a user account but is designed for machines, not people.
