Machine identity with accountable authority.
Know which service, workload, machine or agent is acting and who owns its credentials and lifecycle.
Which non-human principal caused this request, and who is accountable?
Problem → control → outcomeNon-human does not mean ownerless
Workloads, services, devices and agents often operate without an interactive human sign-in. Their identities need a named owner, issuance path, environment and lifecycle. A shared service credential can obscure which agent actually requested an action, even if the API call authenticated successfully.
Machine identity therefore begins with stable attribution: distinguish the platform identity of the workload from the logical principal making a request through it. Record how the machine was enrolled, which task it serves and when credentials should be rotated or revoked.
- Workload and service identity
- Device and machine identity
- Agent identity and task owner
- Credential issuance, rotation and retirement
Identity is not an action grant
A machine credential can prove that a controller belongs to a fleet. It does not determine whether it may change a valve set point now. A service account can authenticate to a cloud API without authority to alter a production security group for every task.
The broader ProofGrid model connects non-human identity with a traceable authority origin, policy envelope and runtime decision. This avoids treating a long-lived credential as permanent, unlimited operational permission.
Lifecycle meets revocation
The machine or agent may change owner, environment, software posture or task. When those facts change, grants tied to the old state should be reassessed. Revoking an agent’s task authority is different from revoking the workload credential used by several applications; both controls can be necessary.
Separate runtime identity from agent identity
A fleet of agents may run under a shared orchestration platform. The platform credential proves that an API call came through a trusted workload, but it does not identify which logical agent, task or delegated grant caused the operation. Conversely, an agent identifier without a trustworthy workload binding can be spoofed. The architecture needs both layers and a defensible association between them.
Inventory ownership is equally important. Every non-human identity should have a responsible team, purpose and retirement path. Otherwise old credentials can survive a project change and remain available to new agents that were never intended to use them.
Identity is the first layer
A machine or non-human identity should identify the workload or logical agent, its owner, credential issuer, runtime and lifecycle. Strong attribution matters because every later authority decision depends on knowing which actor actually made the request. Credential rotation, inventory and retirement remain essential, even when an agent has task-specific grants.
The additional question is permission to cause: which accountable origin authorized this agent to change this target for this task? A valid workload token may reach an API without conveying that task authority. ProofGrid combines identity and access control with authority decisions; identity tooling remains essential.
