ISO 27017 cloud controls, not a footnote to 27001.
ISO/IEC 27017 extends ISO 27002's guidance with cloud-specific security controls — covering the shared-responsibility split between cloud provider and customer, cloud access management, and cloud operations. grComply seeds it as its own control tree, cross-mapped into an existing ISO 27001 ISMS so cloud service providers and consumers can evidence cloud-specific obligations without duplicating the controls they already run.
What is ISO/IEC 27017? ISO/IEC 27017 is a code of practice for information security controls specific to cloud services, extending ISO 27002's general guidance with cloud provider (CSP) and cloud customer (CSC) specific controls — most notably a documented shared-responsibility matrix defining who owns which control.
How grComply benefits your ISO 27017 programme
Shared-responsibility matrix as a first-class control
CLD-6.1 (documented shared responsibility) is modelled as its own control with its own evidence requirement, not a footnote in a contract.
Cloud-specific evidence types, not generic IT evidence
Config exports, IAM exports, and console screenshots map directly to cloud access and operations controls.
Extends your existing 27001 ISMS
27017 loads as a cloud-specific extension in the same tree as ISO 27001, cross-mapped so shared controls aren't re-evidenced.
Cloud logging & monitoring ties to real scan and SIEM evidence
The same scanning and log-evidence pipeline used for every other framework applies here too.
Multi-tenant isolation assurance, made explicit
A dedicated control for virtualization and multi-tenant isolation — unusual outside a framework-agnostic tree that can model it precisely.
Supplier exit evidence sits with vendor risk
Cloud supplier relationship and exit attestations link to the same risk register as any other third-party exposure.
Four cloud-control themes, seeded with real control language
Seeded to cover the organisational, access, operational, and supplier dimensions of cloud-specific security — the parts ISO 27001 alone doesn't spell out.
Organisational cloud controls
Information security policies for cloud services, cloud service information security, and — critically — shared roles and responsibilities between CSP and CSC, documented as its own control.
Access and identity in the cloud
Cloud access control policy, user registration and de-registration for cloud accounts, and secure log-on and privileged cloud access.
Cloud operations & cryptography
Cryptographic controls for cloud data, cloud operational procedures and responsibilities, and logging and monitoring in cloud environments.
Supplier and virtualization
Network security for cloud services, cloud supplier relationships and exit planning, and virtualization/multi-tenant isolation assurance.
Evidence grComply already models for ISO 27017
Real evidence-requirement examples from the seeded control library — the same evidence types every other framework in grComply uses, not a bespoke process for this one.
| Control | Evidence type | Example |
|---|---|---|
| CLD-6.1 — Shared responsibility | Policy document | Documented shared responsibility matrix (CSP vs CSC) |
| CLD-5.1 — Cloud security policy | Policy document | Cloud security addendum or policy |
| CLD-12.4 — Cloud logging & monitoring | SIEM log sample | Cloud audit log configuration evidence |
| CLD-15.1 — Supplier exit | Attestation | Supplier due diligence / exit attestation |
Why this matters: 27017's shared-responsibility matrix is the control most organisations get wrong by leaving it in a contract nobody re-checks — modelling it as a trackable control with its own evidence requirement is what keeps it current as cloud services change.
ISO 27017, in the live workspace
The same grComply workspace shown across the platform — control browser, mapping, evidence, and AI assist apply identically to ISO 27017.
ISO 27017 in grComply
What is ISO/IEC 27017?
ISO/IEC 27017 is a code of practice extending ISO 27002 with cloud-specific security controls, covering the shared-responsibility split between cloud provider and customer, cloud access management, and cloud operations.
Does 27017 replace ISO 27001?
No — it extends an existing ISO 27001 ISMS with cloud-specific controls; it's not a standalone certifiable ISMS on its own.
What is the shared-responsibility matrix, and why does it matter?
It's the documented split of which security controls the cloud provider owns versus which the customer owns — grComply models it as its own control (CLD-6.1) with a required evidence artefact, not an assumption buried in a contract.
Does grComply support multi-tenant isolation evidence?
Yes — a dedicated control for virtualization and multi-tenant isolation assurance exists in the seeded structure, distinct from generic access-control evidence.
Can 27017 evidence cross-map into an ISO 27001 ISMS?
Yes — 27017 loads in the same tree as ISO 27001, and shared controls (like access management) cross-map so evidence isn't duplicated across the two frameworks.
What evidence does grComply expect for cloud logging?
Cloud audit log configuration evidence tied to CLD-12.4, drawn from the same SIEM/logging evidence category used across every other framework.
Who typically needs ISO 27017?
Cloud service providers and cloud-consuming organisations that want to formally evidence cloud-specific security obligations, often alongside a customer or partner's due-diligence requirements.
Can we also run ISO 27018 for cloud privacy?
Yes — ISO/IEC 27018 covers PII protection in public clouds and loads in the same tree as 27017 and 27001.
