📱 Mobile Device Management Skill

🎯 Purpose

This skill enforces mobile device management (MDM) controls for BYOD (Bring Your Own Device) environments, personal device security requirements, and endpoint protection. Based on Hack23 AB's Mobile Device Management Policy, it demonstrates enterprise-grade MDM without enterprise infrastructure.

Key Principle: "BYOD means 'Bring Your Own Disaster'—but only if devices remain unmanaged."

📚 Scope

This skill covers:

📱 BYOD Policy: Personal device security requirements for business use
🔐 Endpoint Protection: Encryption, malware protection, device health
📲 Mobile App Security: Approved apps, containerization, data separation
🔒 Device Encryption: Full device encryption requirements
☁️ Remote Wipe: Data protection for lost/stolen devices
📊 Compliance Monitoring: MDM enrollment, policy enforcement, auditing

⚙️ Security Rules

## Mobile Device Lifecycle

### 1. Pre-Enrollment
- [ ] Assess business need for mobile device
- [ ] Verify device OS meets minimum version requirements
- [ ] Obtain user consent for MDM enrollment (BYOD)
- [ ] Document device in Asset Register

### 2. Enrollment
- [ ] Install MDM profile (AWS WorkMail, Intune, Jamf)
- [ ] Verify encryption enabled
- [ ] Configure screen lock and timeout
- [ ] Test remote wipe capability
- [ ] Install approved business apps
- [ ] Configure VPN for secure access

### 3. Operational Use
- [ ] Monthly MDM compliance review
- [ ] Quarterly OS update verification
- [ ] Semi-annual app inventory audit
- [ ] Annual policy acknowledgment

### 4. Incident Response
- [ ] Device loss: Immediate credential lockdown
- [ ] Remote wipe: Selective or full based on risk
- [ ] Log review: Check for unauthorized access
- [ ] Documentation: Update incident log

### 5. Retirement
- [ ] Remove from MDM console
- [ ] Selective wipe of corporate data
- [ ] Update Asset Register status
- [ ] Document disposal method
