ECC 2-6-4 requires organizations to run periodic reviews of mobile device compliance — verifying that enrolled devices meet policy baselines and remediating or documenting exceptions — and you can satisfy this efficiently by combining a modern MDM with policy automation, scheduled reporting, and simple integrations into your ticketing or GRC system.
\n\nWithin the Compliance Framework and the Practice requirements, Control 2-6-4 focuses on repeatable, auditable checks of mobile device posture. Key objectives are to (1) ensure devices remain enrolled and managed, (2) validate baseline security controls (encryption, passcode, minimum OS, jailbreak/root detection, managed app control), (3) document noncompliant devices and remediation actions, and (4) retain review evidence for audits. Implementation notes include establishing scope (corporate vs BYOD), cadence (risk-based), automated evidence gathering, and a documented remediation workflow.
\n\nPick a cadence based on risk: high-risk orgs or those with regulated data should run automated compliance checks daily and a formal review monthly; typical small businesses can run automated checks nightly with a human review monthly or quarterly. Scope should include all devices with access to corporate accounts/data: iOS, Android (work profiles), and any Windows or macOS devices managed by the same MDM solution. For BYOD, review both device-level posture and app-level controls (MAM) because full device wipe may not be acceptable.
\n\nStart by translating the ECC controls into concrete MDM policies: require device encryption (File Protection / Android encryption), enforced passcode rules (min length, complexity, max grace period), minimum OS versions (e.g., iOS 16+, Android 12+), prevent jailbroken/rooted devices, require MDM enrollment and active check-ins, enforce app allowlists/blacklists and managed app configurations, and enable remote wipe/selective wipe. Configure these as device compliance policies (Intune), configuration profiles (Jamf), or policy sets (Workspace ONE). Tag devices with attributes such as \"business_unit\" or \"sensitivity\" to support scoped reviews.
\n\nExample policy specifics you can deploy now: (1) Require encryption: BitLocker or FileVault for desktops, iOS data protection = Complete; (2) Passcode: minimum 6 digits or alphanumeric, maximum inactivity 5 minutes; (3) Minimum OS: block access for older OS versions using conditional access rules; (4) Jailbreak/root detection: set device compliance to noncompliant if compromised; (5) Enrollment: block unenrolled devices at conditional access. In Microsoft Intune, implement a Device compliance policy and set assignment scope; in Jamf, create Configuration Profiles and Smart Groups. Use MDM health checks such as last check-in < 24 hours to mark devices needing attention.
\n\nAutomation should collect compliance status, config drift, and device metadata to an evidence store. Use vendor APIs: Microsoft Graph for Intune (e.g., GET /deviceManagement/managedDevices or /deviceManagement/deviceCompliancePolicyDeviceStatus), Jamf Pro API (/JSSResource/mobiledevices), or VMware Workspace ONE APIs. Schedule an Azure Function, AWS Lambda, or cron job to call the API nightly, normalize results (device ID, user, compliance state, failing settings, last check-in), and push to a CSV, S3, GCS, or directly to your GRC. Example pseudo-step: 1) authenticate to Graph via app registration, 2) query devices failing compliance, 3) export to S3, 4) create tickets for noncompliant devices in ServiceNow via its API. Keep API responses (or snapshots) as time-stamped evidence for audits.
\n\nHere is a minimal Microsoft Graph flow (pseudo): 1) Acquire access token for https://graph.microsoft.com/.default. 2) GET https://graph.microsoft.com/v1.0/deviceManagement/managedDevices?$filter=complianceState ne 'compliant'&$select=id,deviceName,userPrincipalName,complianceState,osVersion,lastSyncDateTime. 3) Transform into a CSV and push to the GRC/ticketing system. For Jamf, use GET /JSSResource/mobiledevices/match/{id} to pull device detail including enrolled status and security properties. Schedule these scripts to run automatically and retain outputs for your audit window (e.g., 12+ months depending on policy).
\n\nAutomation should not only report failures but trigger remediation steps: send an automated push notification or email to the device owner with remediation instructions, apply a quarantine profile (restrict access to corporate email), escalate to ticketing after X failed attempts, and optionally perform a selective wipe if a device is lost or confirmed compromised. Implement conditional access to block access for devices flagged as noncompliant. Example workflow: nightly scan → device flagged as noncompliant → push remediation message + open ticket → 48-hour user remediation window → if unresolved, revoke access and escalate to IT for further action. Maintain logs of each action to satisfy the documentation requirement in Compliance Framework evidence collection.
\n\nRisks of not implementing ECC 2-6-4 controls are tangible: drift in device posture increases the chance of credential theft, data exfiltration, lateral movement, and compliance violations. Unmanaged or noncompliant devices are common entry points for ransomware (via malicious apps or unpatched OS), and auditors will expect proof of periodic review and remediation; failing to provide that increases the likelihood of penalties, contractual breaches, or loss of cyber insurance coverage.
\n\nFor a small business with ~50 employees and a BYOD policy: enroll corporate accounts in Intune MAM for app control and require enrollment for users accessing sensitive apps. Schedule nightly Intune compliance exports to a Google Sheet or Slack channel. Create a Smart Group (Jamf) or Dynamic Group (Intune) for devices with \"lastSyncDateTime > 3 days or complianceState != compliant\" and assign automated remediation messages to that group. Keep the monthly human review to validate edge cases (e.g., contractor devices, exemptions) and store a signed reviewer checklist in the Compliance Framework evidence library. This approach keeps overhead low while meeting the documentation and remediation expectations of ECC 2-6-4.
\n\nCompliance tips and best practices: maintain a clear device classification (corporate, BYOD, contractor), use tags for scope, enforce least privilege with Conditional Access, test automation on a pilot group first, encrypt logs and secure API credentials, retain evidence per your retention policy, and document your remediation SLA. Regularly review and update minimum OS and policy settings (e.g., update min OS after vendor EoL) so your automated checks remain meaningful.
\n\nSummary: to meet ECC 2-6-4, combine your MDM's compliance policies with scheduled automation to collect device posture, generate auditable evidence, and trigger remediation workflows. Use vendor APIs (Intune Graph, Jamf API, Workspace ONE), schedule regular exports, integrate with ticketing/GRC, and define a risk-based cadence and SLA for human review. By codifying checks and responses you reduce manual effort, improve security posture, and create the audit trail required by the Compliance Framework.
