Workload API

IT Concepts
The Workload API is the local interface defined by the SPIFFE specification through which workloads retrieve their SVIDs from a SPIRE agent. It operates over a Unix domain socket and requires no authentication from the calling workload, relying instead on kernel-level process inspection to verify identity before returning credentials. By surfacing identity through a standard local API, SPIFFE allows workloads to obtain and rotate credentials automatically without embedding secrets in configuration or code.

Workload Attestation

IAM Concepts
Workload attestation is the process by which a SPIRE agent verifies that a requesting process is actually the workload it claims to be before issuing a SVID. Attestation uses platform-specific evidence such as Kubernetes pod labels, AWS instance metadata, or process attributes to confirm workload authenticity at runtime. It is the mechanism that replaces static pre-shared secrets with dynamic, context-verified identity, and it is fundamental to how SPIFFE-based systems eliminate credential bootstrapping problems.

Workload Identity Management

Security Concepts
Workload identity management governs how non-human entities, applications, services, containers, scripts, and automated processes) authenticate and authorize their interactions across distributed systems.

Workload IGA

Identity Types
Workload IGA (Identity Governance and Administration for Workloads) extends traditional identity governance principles, such as access reviews, provisioning, and policy enforcement, to non-human identities like applications, services, and AI agents. It ensures that every workload has the right access, at the right time, for the right purpose.

Workload

Identity Types
A specific task, application, or process running on a machine or within a computing environment, often associated with cloud-based or distributed systems.

Workload Identity Federation (WIF)

Identity Types
Workload Identity Federation allows workloads running in one environment (e.g., on-premises or a third-party cloud) to authenticate and access resources in another environment (e.g., public cloud) without managing long-term credentials. It typically leverages federated trust models like OIDC (OpenID Connect) for secure authentication.
