Acceptable use of assets

ISO/IEC 27017 Clause 8.1.3 requires you to define, document, and implement rules for acceptable use of information and the assets that store, process, or transmit it in cloud services. Operationally, you need an enforceable acceptable use policy mapped to cloud asset types, embedded into onboarding, access control, monitoring, and third-party governance, with audit-ready evidence.

Key takeaways:

• Write cloud-specific acceptable use rules for information and information-processing assets, not a generic “employee handbook” policy.
• Implement the rules through technical controls (access, logging, DLP where applicable), process controls (onboarding, exceptions), and third-party terms.
• Keep proof: versioned policy, acknowledgements, enforcement records, exceptions, and control mappings to cloud environments.

“Acceptable use of assets” sounds simple until an incident forces you to explain what “acceptable” meant for production cloud consoles, customer data exports, shared SaaS drives, and contractor-managed endpoints. ISO/IEC 27017:2015 Clause 8.1.3 makes this a requirement: you must identify, document, and implement rules for acceptable use of information and associated assets in cloud services. The word “implemented” is where most programs fail; auditors look for operating evidence, not a PDF.

For a Compliance Officer, CCO, or GRC lead, the fastest path is to treat acceptable use as a control family with three layers: (1) clear behavioral rules tied to asset and data types, (2) technical and workflow enforcement in your cloud stack, and (3) accountability (acknowledgement, monitoring, and exceptions). This page gives you requirement-level guidance you can put into a control narrative, assign to owners, and test.

If you manage third parties (cloud providers, SaaS vendors, MSPs, contractors), acceptable use also becomes a contracting and access governance problem. Your rules must flow down to anyone who touches your cloud information assets.

Regulatory text

Text (requirement): “Rules for the acceptable use of information and of assets associated with information and information processing facilities shall be identified, documented and implemented for cloud services.” (ISO/IEC 27017:2015 Information technology — Security techniques — Code of practice for information security controls based on ISO/IEC 27002 for cloud services)

Operator interpretation (what you must do):

1. Identify rules: Decide what users and administrators may and may not do with cloud information and cloud assets (accounts, endpoints, consoles, storage, logs, keys, CI/CD, etc.).
2. Document rules: Publish them in a controlled policy/standard with scope, roles, and enforcement.
3. Implement rules: Put the rules into operation through onboarding, access control, technical guardrails, monitoring, and consequences for violations in cloud services.

A common audit failure: “We have an acceptable use policy” that never mentions cloud admin consoles, customer tenant data, API keys, or SaaS sharing. ISO 27017 is explicit that this is for cloud services. (ISO/IEC 27017:2015 Information technology — Security techniques — Code of practice for information security controls based on ISO/IEC 27002 for cloud services)

Plain-English requirement (what “acceptable use of assets” means)

You must clearly define how people and systems are allowed to use:

• Information (company data, customer data, logs, code, secrets).
• Assets associated with information (devices, cloud accounts, SaaS tenants, storage buckets, containers, IAM roles, encryption keys, collaboration platforms).
• Information processing facilities (cloud infrastructure, CI/CD runners, production databases, analytics platforms).

Then you must make those rules real: users agree to them, access is granted based on role and need, risky actions are blocked or detected, and exceptions are controlled.

Who it applies to

Entity types

• Cloud service customers running workloads in IaaS/PaaS/SaaS where their users administer, process, store, or share information. (ISO/IEC 27017:2015 Information technology — Security techniques — Code of practice for information security controls based on ISO/IEC 27002 for cloud services)
• Cloud service providers who operate cloud services and must set acceptable use for both internal operators and customer-facing service use. (ISO/IEC 27017:2015 Information technology — Security techniques — Code of practice for information security controls based on ISO/IEC 27002 for cloud services)

Operational contexts where it matters most

• Production cloud administration (break-glass access, console sessions, privileged APIs).
• Data movement (exports, downloads, syncing to local devices, sharing links).
• Collaboration tooling (SaaS drives, chat, ticketing attachments).
• Software delivery (source repos, build artifacts, signing keys, pipeline secrets).
• Third-party access (contractors, support vendors, implementation partners).

What you actually need to do (step-by-step)

1) Define scope and asset categories (make it cloud-real)

Create a short scoping statement: “This standard applies to information and information-processing assets used to deliver, administer, or support cloud services.” Then define asset categories you can govern:

• Cloud identities (workforce IAM, service accounts)
• Admin interfaces (cloud consoles, SaaS admin panels)
• Data stores (object storage, managed DBs, file shares)
• End-user endpoints with cloud access (managed devices, BYOD if permitted)
• Secrets and cryptographic material (API keys, tokens, KMS/HSM keys)
• Logging/monitoring data (SIEM, audit logs)

Deliverable: Acceptable Use Standard (Cloud Assets) that references your asset inventory approach (even if inventory maturity is evolving).

2) Write enforceable rules, not slogans

Rules should be testable and tied to common risk events. Include:

• Data handling: where sensitive data may be stored; restrictions on personal email, personal cloud drives, removable media if relevant.
• Sharing and collaboration: limits on public links, external sharing, anonymous access, and embedding secrets in tickets/chats.
• Privileged access: MFA requirements, prohibition on shared admin accounts, rules for break-glass.
• Software and automation: approved CI/CD patterns, secret storage requirements, restrictions on running unapproved scripts in production contexts.
• Logging and monitoring: prohibition on disabling audit logs; requirement to protect logs as sensitive information.
• Prohibited actions: crypto-mining, bypassing security controls, shadow IT SaaS connections, copying production data into non-production without approval.

Make each rule assign an owner for enforcement (IT, Security, Cloud Platform, DevOps, HR, Procurement).

3) Embed the rules into access and onboarding workflows

Auditors want “implemented.” Do these operational moves:

• Add acceptable use acknowledgement to employee onboarding and contractor onboarding.
• Gate access to cloud consoles and SaaS admin with: training completion, policy acknowledgement, and manager approval.
• Add just-in-time reminders in access request forms: “By requesting admin access you agree to…”
• Require third parties to accept equivalent terms via MSA/SOW and access agreements.

Evidence tip: keep acknowledgement logs and access ticket records tied to identity.

4) Implement technical guardrails that match the rules

Pick a small set of guardrails that directly enforce high-risk rules:

• Enforce MFA and conditional access for cloud/SaaS admin.
• Centralize identity; remove shared accounts where possible.
• Enable cloud audit logging and alert on disabling logs.
• Set safe defaults for sharing (block public links by default where feasible).
• Implement secret scanning in repositories and CI where possible.

You do not need to solve every control at once, but you must show that your highest-risk acceptable use rules have a technical or workflow enforcement mechanism.

5) Create a controlled exceptions process (and use it)

Acceptable use always has edge cases (support dumps, customer troubleshooting, regulated data handling). Build an exception form that captures:

• Business justification
• Data/asset types affected
• Compensating controls
• Expiration and review owner

Store exceptions centrally and tie them to risk acceptance. This is often the difference between “policy violation” and “approved deviation.”

6) Monitor and enforce consistently

Implementation includes consequences and follow-through:

• Define who reviews alerts (SecOps, CloudOps).
• Define escalation: manager notification, access removal, HR process if needed.
• Track violations as tickets with disposition (false positive, coaching, disciplinary, control gap).

If you cannot show enforcement evidence, auditors may treat the policy as non-operational.

7) Extend acceptable use to third parties

For third parties with access to your cloud assets or data:

• Put acceptable use clauses in contracts (security exhibits).
• Require least-privilege access, time-bound accounts, and logging.
• Include acceptable use checks in third-party onboarding and periodic access reviews.

Daydream can help you centralize third-party onboarding artifacts (policy acknowledgement, access approvals, exceptions) so audits do not turn into a scavenger hunt.

Required evidence and artifacts to retain

Keep artifacts that prove “identified, documented, implemented” in cloud services:

Policy and governance

• Acceptable Use Policy and/or Cloud Acceptable Use Standard (versioned, approved)
• Scope statement for cloud services and asset categories
• Roles and responsibilities (RACI) for enforcement

Operational proof

• User/contractor policy acknowledgements (HR system exports, GRC attestations)
• Training completion records for privileged users
• Access request and approval records for cloud/SaaS admin roles
• Configuration evidence for key guardrails (MFA enforcement screenshots/exports, logging enabled evidence)
• Monitoring and incident records tied to acceptable use violations
• Exceptions register with approvals and expirations
• Third-party contract clauses or security addenda referencing acceptable use expectations

Testing/audit support

• Internal audit or control testing results and remediation tickets
• Periodic access review results for privileged access

Common exam/audit questions and hangups

Auditors and assessors tend to probe:

• “Show me where acceptable use rules are documented for cloud services.” (They will reject a generic policy with no cloud references.)
• “How do you ensure contractors and third parties follow the same rules?”
• “How do you prevent or detect prohibited actions, like disabling audit logs or public data sharing?”
• “How do you manage exceptions, and who approves them?”
• “Prove implementation: show acknowledgement, training, access gating, and at least one enforcement example.”

Hangup to anticipate: teams present a policy but cannot show evidence of acknowledgement, or they cannot show it applies to cloud admin actions.

Frequent implementation mistakes (and how to avoid them)

1. Mistake: generic acceptable use with no cloud asset mapping.
   Fix: add a cloud appendix listing assets (SaaS tenants, IAM, keys, storage) and rules for each.

2. Mistake: rules that cannot be tested.
   Fix: rewrite “Use responsibly” into “Do not store customer data in personal cloud storage” or “Do not create public links for internal documents without approval.”

3. Mistake: no exception path, so teams work around you.
   Fix: publish a fast exception workflow with compensating controls and expirations.

4. Mistake: third-party access is excluded.
   Fix: make third-party acceptance part of onboarding and contracts; log their actions; time-box access.

5. Mistake: enforcement is ad hoc.
   Fix: create a simple violation handling playbook with owners and ticketing.

Enforcement context and risk implications

No public enforcement cases were provided in the source catalog for this specific ISO clause, so focus on audit and assurance risk. The practical risk is operational: unclear acceptable use rules increase the chance of unauthorized data disclosure, misuse of privileged access, and inability to prove control effectiveness during customer due diligence, ISO audits, or security reviews. ISO/IEC 27017 assessors typically treat “documented but not implemented” as a control failure because the clause explicitly requires implementation for cloud services.

Practical execution plan (30/60/90-day)

First 30 days (baseline and publish)

• Inventory the cloud-relevant asset categories you will govern (identity, admin consoles, data stores, endpoints, keys, logs).
• Draft a cloud-specific acceptable use standard with testable rules and an exceptions process.
• Route for approval and publish in your policy repository.
• Add acknowledgement to onboarding for employees and contractors.
• Update third-party onboarding checklist to include acceptable use acceptance.

Next 60 days (implement and collect evidence)

• Gate privileged access on training + acknowledgement + manager approval.
• Turn on or validate audit logging for core cloud environments; document evidence.
• Configure baseline sharing restrictions in core SaaS platforms where feasible.
• Stand up exceptions register and run the first review cycle.
• Run a tabletop exercise: “public link created” or “production data export” and confirm your enforcement workflow.

Next 90 days (scale and test)

• Expand rules and guardrails to additional SaaS and business units.
• Implement monitoring for top unacceptable actions (log disablement, public sharing, anomalous downloads) and track response tickets.
• Perform control testing: sample users for acknowledgement; sample access grants; sample exceptions; sample alerts.
• Package audit-ready evidence in a single folder or GRC system record. Daydream is a practical place to keep policy versions, attestations, access evidence, and third-party artifacts aligned to this requirement.

Frequently Asked Questions

Do we need a separate acceptable use policy for cloud, or can we update the existing one?

You can update the existing policy, but it must explicitly cover cloud services and cloud asset types. Assessors will look for rules that apply to cloud admin access, SaaS sharing, cloud storage, and data processing in cloud environments. (ISO/IEC 27017:2015 Information technology — Security techniques — Code of practice for information security controls based on ISO/IEC 27002 for cloud services)

What counts as an “asset” under acceptable use in a cloud context?

Treat cloud identities, SaaS tenants, cloud consoles, storage locations, encryption keys, CI/CD systems, and endpoints with cloud access as assets. If it can store, process, transmit, or administer information, it belongs in scope. (ISO/IEC 27017:2015 Information technology — Security techniques — Code of practice for information security controls based on ISO/IEC 27002 for cloud services)

How do we prove the policy is “implemented”?

Show acknowledgements, access gating tied to the policy, technical guardrails (like MFA and audit logging), and at least one example of monitoring or enforcement. Implementation evidence matters as much as the written rule. (ISO/IEC 27017:2015 Information technology — Security techniques — Code of practice for information security controls based on ISO/IEC 27002 for cloud services)

Do contractors and third parties need to acknowledge acceptable use?

Yes, if they access your cloud services, data, or administrative interfaces. Capture acceptance in contracts, onboarding attestations, or access agreements and retain it with the access approval record.

What if a team needs to break a rule for an urgent incident?

Allow it only through a defined exception or emergency access process with logging, approvals after the fact if necessary, and an expiration. Document compensating controls and review the event to decide whether the rule or tooling needs adjustment.

How detailed should acceptable use rules be for engineers vs. general staff?

Keep a single policy backbone, then add role-based addenda for privileged and technical users (cloud admins, developers, support engineers). The addenda should cover production access, data exports, secret handling, and logging expectations.
