Mobile Computing and Communications

HITRUST’s Mobile Computing and Communications requirement means you must have a formal, approved policy and implement security measures that address the real risks of mobile devices and mobile communications, especially in unprotected environments. Operationalize it by standardizing device enrollment, encryption, secure connectivity, access controls, and user rules, then retaining proof that policy and controls are implemented and monitored. ¹

Key takeaways:

• You need both a formal policy and implemented technical/administrative safeguards for mobile work. ¹
• The control’s exam “gotcha” is unprotected environments: public Wi‑Fi, travel, home offices, and shoulder-surfing risks must be covered. ¹
• Evidence must show the policy is not shelfware: enrollment, configurations, logs, and exceptions must map to the policy.

Mobile computing expands your control boundary beyond the office. Laptops, phones, tablets, and mobile hotspots routinely handle regulated data while employees travel, work remotely, or connect through unknown networks. HITRUST CSF v11 01.x turns that reality into a clear requirement: you need a formal policy and security measures that specifically protect against the risks of mobile computing and communications, including work performed in “unprotected environments.” ¹

For a Compliance Officer, CCO, or GRC lead, the fastest path is to treat this as a combined governance-and-operations requirement. Governance means a policy that sets enforceable rules: which devices are allowed, what data can be stored locally, what encryption and authentication are mandatory, what “secure communications” means, and how exceptions are approved. Operations means you can prove devices are enrolled, configurations are enforced, risky connections are controlled, and loss/theft events are handled consistently.

This page translates the requirement into a practical build plan, the evidence auditors ask for, and common failure modes that delay HITRUST assessments.

Regulatory text

HITRUST CSF v11 01.x excerpt: “A formal policy shall be in place, and appropriate security measures shall be adopted to protect against the risks of using mobile computing and communication facilities. The policy shall cover risks arising from working with mobile computing equipment in unprotected environments.” ¹

What the operator must do:

1. Publish and maintain a formal mobile computing/communications policy (approved, owned, versioned). ¹
2. Implement appropriate security measures that match the policy’s commitments (technical settings and operational processes). ¹
3. Ensure the policy explicitly addresses “unprotected environments” (home networks, public Wi‑Fi, travel, shared spaces). ¹

Plain-English interpretation (what this requires in practice)

This control expects you to prevent common mobile-work failures: lost devices exposing data, unauthorized family/shared use, insecure wireless connections, phishing on mobile, and data leakage through consumer apps. You pass by showing that mobile use is governed by written rules and that endpoints and communications are configured to enforce those rules. A policy alone is not enough; a pile of MDM settings without a policy also fails.

Who it applies to

Entity scope: All organizations under HITRUST CSF. ¹

Operational scope (where it bites):

• Workforce members using company-owned or personally owned mobile devices for work (BYOD).
• Anyone accessing corporate email, collaboration tools, EHR/clinical apps, file shares, ticketing systems, or admin consoles from mobile endpoints.
• Third parties that access your systems via mobile endpoints (consultants, contractors) when you permit it; manage this via your access and third-party requirements, but align their mobile access to your policy expectations.

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

Use this sequence to build quickly and produce clean audit evidence.

1) Define your mobile scope and risk decisions

• Inventory the device types and access paths: laptops, smartphones, tablets; VPN, ZTNA, VDI, browser-based access, mobile apps.
• Classify permitted data actions: view-only vs download; local storage allowed or prohibited; copy/paste restrictions for sensitive apps if feasible.
• Decide ownership models: corporate-only, BYOD allowed with controls, or BYOD prohibited.

Output: a one-page “mobile scope statement” that you can attach to or reference in policy and standards.

2) Publish a formal Mobile Computing & Communications Policy

Minimum policy topics to include (keep it enforceable):

• Approved device requirements: supported OS versions, no jailbreak/root, screen lock, auto-lock timer, device encryption requirement, and secure boot where available.
• Enrollment and management: devices must enroll in your endpoint management tool (MDM/EMM/UEM) before accessing corporate data.
• Authentication: MFA required for remote access and cloud apps; restrictions on shared accounts.
• Secure communications: rules for public Wi‑Fi, hotspot use, VPN/secure tunnel requirements, and prohibition of insecure protocols where relevant.
• Data handling: local storage rules, backup rules, removable media stance, and approved work apps (and disallowed consumer apps for sensitive data).
• Physical security: don’t leave devices unattended; travel guidance; privacy screens for sensitive work in public.
• Incident requirements: loss/theft reporting window stated as an internal requirement; remote wipe authorization; escalation path.
• Exceptions: documented approval, compensating controls, review cadence.

Practical drafting tip: Write the policy so you can enforce it with configuration baselines. If you can’t enforce a rule, rewrite it as a process requirement (e.g., “must not store regulated data locally” becomes “access regulated systems through managed apps that block local export”).

3) Implement baseline technical controls for devices

You need “appropriate security measures.” ¹ Common baseline set:

• Device encryption: full-disk encryption on laptops; native encryption on mobile OS; escrow recovery keys where applicable.
• Strong device access control: PIN/biometrics, lock timeout, failed attempt behavior.
• Endpoint management enforcement: configuration profiles, compliance checks, and conditional access (block access if noncompliant).
• Patch/OS currency: enforce minimum versions and block outdated devices from email and core apps.
• Remote wipe/lock: ability to wipe corporate data on lost devices; document who can trigger it.
• Malware/EDR (as applicable): laptops should have endpoint protection; mobile may rely on OS controls plus MDM risk signals depending on your stack.
• Backups: ensure corporate data syncs to managed services, not consumer backups, when sensitive data is involved.

Evidence mindset: every baseline should produce an exportable report or screenshot from the management console showing compliance.

4) Secure mobile communications (the “communications” half)

Address the common unprotected-environment risks directly:

• Public Wi‑Fi rule: require secure tunneling for access to sensitive systems or block access unless on trusted networks (your policy chooses the method).
• VPN/secure access: define when VPN is required vs when a hardened app gateway/conditional access is acceptable.
• Certificate-based Wi‑Fi / device certificates: if you support corporate Wi‑Fi, require managed certificates for access from mobile endpoints.
• Email and messaging: require managed mail profiles; restrict forwarding to personal accounts for regulated data.
• Bluetooth/NFC: set expectations for discoverability and pairing hygiene if relevant to your environment.

5) Train users on “unprotected environments”

The requirement explicitly calls this out. ¹ Your training should be short and scenario-based:

• Working in airports/cafes (shoulder surfing, untrusted Wi‑Fi).
• Traveling with devices (theft risk, border searches if applicable to your org’s risk posture).
• Home office basics (screen privacy, locking, separating work/personal use where required).

Tip: Make training attestations easy to retrieve during audit.

6) Operationalize exceptions and enforcement

• Exception intake: who requests, what must be justified, compensating controls, expiry, and review.
• Offboarding and access removal: ensure mobile access is revoked quickly when roles change or employment ends.
• Monitoring and response: define who reviews device compliance and how incidents (lost device, suspicious login) are handled.

7) Validate and document

Before an assessment, run a “mobile control self-test”:

• Pick a sample of devices and confirm policy-required settings are present.
• Confirm conditional access blocks noncompliant devices.
• Confirm you can produce evidence within a day without custom work.

Required evidence and artifacts to retain

Keep artifacts that prove both governance and execution:

• Mobile Computing & Communications Policy (approved, version history, owner).
• Mobile standards/baselines (MDM configuration profiles; encryption and lock requirements).
• Device inventory (managed devices list; ownership status if tracked).
• Compliance reports from MDM/endpoint tools (encryption status, OS versions, compliance posture).
• Conditional access rules exports/screenshots (access blocked for noncompliance).
• Training records and acknowledgments covering mobile and unprotected environments.
• Incident records for lost/stolen devices and actions taken (remote wipe/lock approvals).
• Exception register with approvals, compensating controls, and closure evidence.

Common exam/audit questions and hangups

Expect these, and prepare “one-click” evidence:

• “Show me the policy language for unprotected environments.” ¹
• “How do you ensure only managed devices access email and sensitive apps?”
• “Prove encryption is enabled across the mobile fleet.”
• “How do you handle BYOD? Where is that documented, and how do you enforce it?”
• “What happens when a device is lost? Show a real ticket.”
• “How do you control public Wi‑Fi risk? Is VPN required, or do you use conditional access?”

Frequent implementation mistakes (and how to avoid them)

1. Policy doesn’t match reality.
   Fix: write policy after you confirm what MDM/IdP controls you can enforce; align wording to actual enforcement.

2. No explicit “unprotected environments” coverage.
   Fix: add a dedicated policy section with clear do/don’t rules for public places, travel, and home networks. ¹

3. BYOD ambiguity.
   Fix: state whether BYOD is permitted; if yes, require enrollment and define corporate data separation expectations.

4. Evidence scattered across tools.
   Fix: maintain an “audit packet” folder with quarterly exports and screenshots labeled to the control.

5. Exceptions become permanent.
   Fix: require expirations and periodic review; close or renew exceptions with current justification.

Enforcement context and risk implications

No public enforcement cases were provided in the source catalog for this requirement, so this page avoids mapping to specific regulatory actions. Practically, mobile controls reduce the likelihood and impact of common events: device loss/theft, unauthorized access from unmanaged endpoints, and data exposure over insecure networks. Those events can trigger notification duties and contractual failures even when a specific enforcement case is not cited.

Practical 30/60/90-day execution plan

Use phases to move from policy to enforced controls without guessing timelines.

First 30 days (Immediate)

• Confirm scope: device types, users, apps, and remote access methods.
• Draft and approve the Mobile Computing & Communications Policy with an “unprotected environments” section. ¹
• Identify the enforcement stack (MDM/EMM, IdP conditional access, endpoint protection) and owners.
• Produce a minimum evidence set: current device inventory and a baseline compliance export (even if incomplete).

Next 60 days (Near-term)

• Enroll devices into MDM/EMM/UEM; implement minimum baselines (encryption, lock, OS minimums).
• Turn on conditional access to block noncompliant devices for core services (email, file storage, clinical apps as applicable).
• Publish user training focused on mobile and unprotected environments; collect acknowledgments.
• Stand up the exception process and register.

Next 90 days (Stabilize and prove)

• Expand coverage to remaining populations (contractors/third parties with access, high-risk roles, privileged access users).
• Run a mobile tabletop exercise: lost device scenario and suspicious login from public network.
• Create a recurring review: device compliance reporting, exception review, and policy refresh workflow.
• Assemble a ready-to-share audit packet mapped to HITRUST 01.x.

Frequently Asked Questions

Does this requirement force us to ban BYOD?

No. It requires a formal policy and appropriate safeguards for mobile risks, including unprotected environments. ¹ You can allow BYOD if you can enforce your rules (for example, enrollment, conditional access, and remote wipe of corporate data).

What counts as “mobile computing and communication facilities”?

Treat any portable endpoint and its connectivity as in-scope: laptops, phones, tablets, and the ways they connect to corporate resources (Wi‑Fi, cellular, VPN, cloud access). The safe approach is to scope by access to sensitive systems, not by device brand.

What do auditors usually want to see first?

They typically start with the approved policy and then ask for proof the policy is enforced, such as MDM compliance reports and conditional access settings. They will also check that unprotected environments are explicitly addressed in policy language. ¹

If we only allow browser access to systems, do we still need mobile controls?

Yes. Browser-only access still occurs from endpoints that can be lost, compromised, or connected over untrusted networks. Your controls may shift toward conditional access, device compliance checks, and session controls, but you still need the policy and measures. ¹

How should we handle lost or stolen devices to satisfy this control?

Your policy should require prompt reporting and define who can lock/wipe devices and how access tokens/sessions are revoked. Keep incident tickets that show the workflow was followed, including actions taken and approvals.

Where does Daydream fit if we’re trying to operationalize this quickly?

Daydream can help you organize the evidence pack for HITRUST 01.x, assign control owners, and keep exports (policies, MDM reports, exceptions) in a single audit-ready workflow so you can answer assessor requests without scrambling.
