Treat them as privileged change channels, not developer conveniences. Separate read, plan, approve, and apply permissions, and require version-controlled evidence for every change. If the tool can alter control planes, roles, or portal settings, then its identities belong inside access review and offboarding processes.
Why This Matters for Security Teams
Declarative CLI tools are often treated as harmless operator shortcuts because they describe desired state instead of pushing ad hoc commands. That assumption breaks down quickly when the same tool can change API gateway policies, portal settings, roles, or tenant-wide configuration. At that point, the CLI is a privileged change channel and should be governed like any other NHI-controlled path to production. NHI Mgmt Group notes that only 5.7% of organisations have full visibility into their service accounts, which makes hidden CLI identities a serious audit gap, as described in the Ultimate Guide to NHIs.
The security issue is not the syntax of the tool, but the identity and authority behind it. If a declarative CLI can plan, approve, and apply state changes, it can be used to bypass change management, concentrate privilege in a single token, and obscure who authorized what. Current guidance from the NIST Cybersecurity Framework 2.0 supports controlling privileged change activity through governance, least privilege, and traceable evidence. In practice, many teams discover risky CLI sprawl only after a platform setting has already been changed outside the review path.
How It Works in Practice
Teams should govern declarative CLI tools by separating the workflow into distinct permissions and identities. Read access should allow inspection only. Plan access should generate proposed state without the ability to modify anything. Approve access should be reserved for reviewers with change authority. Apply access should be limited to the smallest possible set of operator or automation identities, with strong logging and short-lived credentials. This maps well to NHI lifecycle thinking in the Ultimate Guide to NHIs — Lifecycle Processes for Managing NHIs.
- Bind the CLI to a distinct workload identity, not a shared human account.
- Require version-controlled change files or pull requests as evidence before apply.
- Make the approval step independent from the identity that runs the apply step.
- Log the command, diff, approver, and target resource in a durable audit trail.
- Revoke or rotate tokens when the tool, pipeline, or operator is no longer active.
This approach is consistent with the NIST CSF emphasis on controlled access and traceability, and it helps align API platform governance with broader regulatory and audit expectations. It also addresses a common NHI failure mode: 97% of NHIs carry excessive privileges, so a single over-scoped CLI token can become a broad control-plane risk. These controls tend to break down when teams share one long-lived automation token across environments, because approval and execution become indistinguishable.
Common Variations and Edge Cases
Tighter CLI control often increases delivery overhead, requiring organisations to balance deployment speed against auditability and rollback confidence. That tradeoff becomes sharper in platform teams that manage many tenants, regions, or ephemeral test environments. Current guidance suggests that not every environment needs the same approval depth, but there is no universal standard for this yet. Lower-risk sandboxes may tolerate broader apply rights, while production API control planes should use the strictest separation of duties.
Another edge case is tooling that appears declarative but still exposes imperative escape hatches. If a CLI can bypass normal state reconciliation, then it needs the same governance as any privileged admin utility. This is especially true when the tool touches secrets, role bindings, or federation settings. NHI Mgmt Group’s Top 10 NHI Issues highlights how excessive privilege and poor offboarding remain persistent risks, and API platform CLIs often inherit both problems when they are not reviewed as identities.
Teams should treat every CLI identity as part of access review, offboarding, and incident response. When a tool can alter platform state, its authority should be time-bound, evidence-backed, and easy to revoke. The model is strongest when the CLI is governed as a NHI with explicit ownership, not as a convenience layer for developers.
