They should manage them under the same governance outcomes, but not with identical operational handling. Human admins, service accounts, and other non-human identities all need least privilege, monitoring, and lifecycle discipline. The controls differ at the implementation level, but the accountability requirement is the same: access must stay explainable and bounded.
What SEBI controls should standardise, and what should stay different?
SEBI controls should standardise the governance outcome, not force identical handling. That means the organisation should expect the same security objectives for people and non-human identities: least privilege, traceable access, approved ownership, periodic review, and timely removal. The implementation still differs because human access is interactive, while service accounts and similar identities are often embedded in systems and automation.
That distinction matters because the control objective is accountability. A reviewer should be able to explain who or what has access, why it exists, what it can reach, and when it will be removed or changed. The mechanism used to prove that may vary by identity type, but the requirement to keep access bounded does not.
Where SEBI controls are interpreted well, they do not treat human admins as a separate governance universe from application accounts or automation credentials. They instead push one policy spine across both: defined ownership, authorised use, monitoring, and evidence of review. The practical difference is that non-human access usually needs more system-level lifecycle discipline, while human access usually needs stronger interactive approval and stronger session oversight.
How the control model changes by identity type
Human access is typically managed around people-centred events such as onboarding, role change, temporary elevation, and departure. Non-human access is usually managed around system events such as deployment, secret issuance, rotation, dependency change, and retirement. The control question is therefore not whether both should be governed, but which lifecycle trigger is most reliable for each.
For humans, the main failure mode is overreach through broad roles, ad hoc exceptions, or delayed removal. For non-human identities, the main failure mode is drift, because a service account, API credential, or token can outlive the business process that created it. That is why identical policy language often produces uneven results unless the operational handling is adjusted to the identity’s behaviour.
SEBI-aligned access control should also account for shared infrastructure and delegated workflows. If a person initiates an action through a system account, or a process acts on behalf of a user, the organisation still needs a clear line of accountability. The control should answer not only “who signed in” but also “what identity exercised authority at the point of access”.
For a broader practitioner view of this boundary, NHIMG’s Human vs Non-Human Identity explains where people and machine access overlap and where their governance needs diverge. The same pattern is reflected in IAM and IGA Basics, which frames access reviews, provisioning, and entitlement governance across both workforce and machine populations.
What good SEBI-aligned governance looks like in practice
Good practice is to keep one access governance standard and two operating patterns. The standard should define ownership, approval, monitoring, review cadence, and revocation expectations. The operating pattern should then split into human and non-human procedures so that evidence collection, rotation, exception handling, and recertification fit the identity’s real usage model.
That usually means human access is managed through joiner-mover-leaver processes, role design, and exception tracking, while non-human access is managed through inventory, secret management, rotation, and dependency mapping. The important point is that both streams feed the same governance record. If an identity cannot be explained in inventory, it is already weak from a SEBI control perspective.
Ownership is the practical bridge between the two. A named business or technical owner should be able to justify why an identity exists, what business service it supports, and what condition ends its life. If the owner cannot produce that answer quickly, the access is not yet governed tightly enough, even if it has technical controls around it.
When teams need a deeper model for this ownership and lifecycle discipline, NHI Ownership and Accountability Guide is useful for the accountability side, while Service Account Security Guide covers the operational controls that are usually missing when organisations scale automation.
Risk and Threat Considerations
When organisations manage human and non-human access inconsistently, the largest risk is control drift. A system may be tightly governed for people but loosely governed for service identities, which creates hidden pathways for privilege accumulation, stale access, and unaudited automation.
Failure mechanism: The access path becomes harder to explain as identities multiply, credentials outlive their purpose, and reviews focus on users while machine credentials escape comparable scrutiny.
Impact: Excessive access can persist long enough to enable unauthorised transactions, lateral movement, or unauthorised system changes while still appearing compliant on paper.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
NIST SP 800-53 Rev 5 sets the technical controls, while ISO/IEC 27001:2022 defines the regulatory obligations.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST SP 800-53 Rev 5 | AC-2 — Account Management | Covers lifecycle governance for both user and non-user access accounts. |
| IA-5 — Authenticator Management | Applies to credentials, tokens, and secrets used by human and non-human access paths. | |
| AC-6 — Least Privilege | Matches the need to bound access outcomes consistently across people and machine identities. | |
| Recommendation — Enforce account inventory, approval, review, and timely disabling for all identity types. Manage secrets and authenticators through rotation, protection, and revocation. Limit each identity to the minimum permissions needed for its approved function. | ||
| ISO/IEC 27001:2022 | A.5.15 — Access control | Directly supports governing access rights under a single policy outcome. |
| A.8.5 — Secure authentication | Supports authentication handling for accounts, credentials, and system access paths. | |
| Recommendation — Define and enforce access control rules for human and non-human identities. Apply secure authentication methods appropriate to each identity type. | ||
Practitioner Guidance
What to verify: Check that every privileged human and non-human identity has a named owner, a declared purpose, a review cadence, and a removal condition. If any one of those is missing, the control is incomplete even if the identity is technically monitored.
Decision rule: If the identity can execute actions without a person actively present, treat lifecycle and revocation discipline as the first control priority; if the identity is interactive, prioritise approval flow, session oversight, and role containment.
Common mistake: Teams often copy human access review processes onto service accounts and then miss the signs of drift, because the right question is not “who approved it last quarter?” but “what system dependency still requires it today?”
Practitioner takeaway: SEBI control design should converge on one accountability model, but the operating controls must reflect how the identity behaves, otherwise the organisation gets formal consistency without real access assurance.
