💼 Management Samenvatting

iOS configuratiebaseline voor iPhone en iPad devices via Intune MDM om bedrijfsdata toegang te controleren en beveiligen.

Implementatie
32u (tech: 16u)
Van toepassing op:
✓ iOS
✓ iPadOS
✓ Intune

iOS devices worden gebruikt voor toegang tot corporate resources (email, Teams, SharePoint, line-of-business apps). configuratiebaseline zorgt voor: (1) Network configuration - WiFi profiles, VPN, certificaatn voor veilige connectivity, (2) Email/calendar configuration - beheerde Exchange ActiveSync profiles, (3) App configuration - beheerde app configurations voor line-of-business apps, (4) Restrictions - Blokkeer risky features (screenshots van beheerde apps, iCloud backup van corporate data, AirDrop voor data exfiltration), (5) Privacy - Advertising ID disabled, diagnostics limited. Zonder configuratiebaseline hebben users inconsistent access, weak beveiligingsinstellings, en gegevenslekken risks.

PowerShell Modules Vereist
Primary API: Microsoft Graph
Connection: Connect-MgGraph
Required Modules: Microsoft.Graph.DeviceManagement

Implementatie

iOS configuratiebaseline via Intune omvat: WiFi profiles met certificaatn, VPN configuration (per-app VPN voor corporate apps), Email/calendar profiles (Exchange ActiveSync managed), App configuratiebeleidsregels, Device restrictions (screenshot blocking, backup restrictions), certificaatn voor authentication. implementeren via Intune device configuration profiles assigned aan iOS device groeps.

Vereisten

  1. Microsoft Intune subscription
  2. iOS/iPadOS devices enrolled in Intune
  3. Azure AD voor identity
  4. certificaatn voor WiFi/VPN (PKI infrastructure)
  5. Network infrastructure (WiFi, VPN)
  6. Exchange Online of on-premises voor email

Implementatie

Gebruik PowerShell-script ios-configuration.ps1 (functie Invoke-Remediation) – iOS configuratiebaseline deployment via Intune.

Configuration profiles via Intune:

  1. WiFi profiles met WPA2/WPA3 Enterprise + certificaatn
  2. VPN profiles (per-app VPN voor beheerde apps)
  3. Email profile (Exchange ActiveSync managed)
  4. certificaat profiles (SCEP of PKCS voor device authentication)
  5. Device restrictions (screenshot block, backup restrictions, AirDrop disabled)
  6. App configuration voor beheerde apps

Monitoring

Gebruik PowerShell-script ios-configuration.ps1 (functie Invoke-Monitoring) – Controleren.

Monitor configuration deployment:

  1. Intune → Devices → iOS → Configuration profiles → Deployment status
  2. Profile assignment success rate (target: >95%)
  3. Configuration errors/failures → troubleshoot
  4. User helpdesk tickets over connectivity issues

Compliance en Auditing

  1. BIO 11.02 - Mobile device management
  2. BIO 12.02 - Mobile security configuration
  3. ISO 27001:2022 A.6.2.1 - Mobile device beleid
  4. ISO 27001:2022 A.8.30 - Network services security

Remediatie

Gebruik PowerShell-script ios-configuration.ps1 (functie Invoke-Remediation) – Herstellen.

Compliance & Frameworks

Automation

Gebruik het onderstaande PowerShell script om deze security control te monitoren en te implementeren. Het script bevat functies voor zowel monitoring (-Monitoring) als remediation (-Remediation).

Risico zonder implementatie

Risico zonder implementatie
High: Zonder iOS configuration baseline = inconsistent connectivity (WiFi/VPN manual setup errors), weak security settings, data leaks (iCloud backup, AirDrop unrestricted), user frustration. Het risico is medium-hoog - enterprise iOS deployment.

Management Samenvatting

iOS Configuration: Intune configuration profiles - WiFi (auto-connect corporate), VPN (automatic tunnel), Email (Exchange ActiveSync), Certificates (PKI deployment), Device restrictions (block iCloud backup, AirDrop contacts-only), App configuration. Activatie: Intune → iOS configuration profiles → Deploy. Gratis (Intune included M365). Implementatie: 16-32 uur (pilot testing + rollout). Essential enterprise iOS deployment - reliable + secure connectivity.
