📱 Hack23 AB — Mobile Device Management Policy

🛡️ Secure Mobile Access Through Pragmatic Device Controls
🎯 Single-Person Founder MDM Strategy for Personal Device Security

🎯 Purpose Statement

Hack23 AB's Mobile Device Management Policy demonstrates that enterprise-grade mobile security doesn't require enterprise infrastructure. As a single-person founder operation, our approach proves that systematic mobile device controls can be pragmatic, effective, and aligned with both security best practices and the Discordian philosophy of mobile security.

BYOD means "Bring Your Own Disaster" - but only if devices remain unmanaged. This policy establishes practical controls for personal mobile devices that access company email and data, implementing the five essential MDM controls: enrollment, policy enforcement, app management, remote wipe capability, and monitoring.

Our transparent approach serves dual purposes: protecting our own operations while demonstrating to clients that effective mobile security is achievable regardless of organization size.

— James Pether Sörling, CEO/Founder

🔍 Scope

In Scope

This policy applies to:

📱 Personal Mobile Devices: Smartphones and tablets owned by the CEO/Founder
💼 Corporate Data Access: Devices accessing AWS WorkMail (hack23.com email)
🖥️ Development Workstations: Ubuntu LTS laptops with encrypted storage
📧 Email Access: All mobile email clients accessing corporate communications
☁️ Cloud Service Access: Mobile access to AWS console, GitHub, and business platforms

Out of Scope

👥 Employee Devices: Not applicable (single-person operation)
🏢 Corporate-Owned Devices: No separate corporate device fleet
🎮 Gaming Consoles: Not used for business purposes
🏠 IoT Devices: Smart home devices without business data access

📚 Reference Documents

This policy integrates with:

🔐 Information Security Policy - Master security framework
🔑 Access Control Policy - Identity and authentication requirements
💻 Asset Register - Device inventory and classification
🏷️ Data Classification Policy - Data handling requirements
🚨 Incident Response Plan - Device loss/theft procedures
🌐 Network Security Policy - Network access controls
🔒 Cryptography Policy - Encryption standards

🍎 The Discordian Philosophy: BYOD Reality

"Nothing is true. Everything is permitted. Your phone bypasses the firewall."

Mobile devices bypass perimeters. They roam networks. They install apps. They get lost. They get stolen. They access company email and then visit malicious websites.

Our Approach: Accept the reality of personal devices, implement pragmatic controls, and maintain the ability to protect corporate data when devices are compromised.

🛡️ The Five Essential MDM Controls

Our implementation of industry-standard mobile device management controls, adapted for single-person founder operations:

1️⃣ Device Enrollment & Inventory

Principle: Register before access. Know what's connecting.

Current Implementation

📱 Mobile Devices: iOS/Android devices enrolled in AWS WorkMail MDM before email access granted
🖥️ Workstations: Ubuntu LTS laptops tracked in Asset Register
🔐 Authentication: All devices require MFA via Google Authenticator or hardware tokens
📝 Inventory: Devices documented in Asset Register with:
- Device type and OS version
- Purpose (email, development, testing)
- Last known location/usage
- Enrollment status and date

Enrollment Process

    style A fill:#FFC107
    style K fill:#4CAF50

2️⃣ Policy Enforcement

Principle: Require passcodes, encryption, updates.

Mobile Device Requirements (AWS WorkMail MDM)

🔒 Device Encryption: Full device encryption mandatory
🔐 Screen Lock: Passcode/biometric required, 5-minute timeout
🚫 Jailbreak Detection: Jailbroken/rooted devices blocked from email access
📲 OS Updates: Latest OS version required (grace period: 30 days after release)
📱 App Restrictions: Corporate email data restricted to approved apps only

Workstation Requirements (Ubuntu LTS)

💾 Full Disk Encryption: LUKS encryption mandatory on all storage devices
🔄 Automatic Updates: Unattended security updates enabled
🔐 Screen Lock: Automatic lock after 5 minutes idle
🔥 Firewall: UFW (Uncomplicated Firewall) enabled with default deny
🛡️ Antivirus: ClamAV or equivalent for malware scanning (when applicable)

Policy Enforcement Matrix

🎯 Control	📱 Mobile (iOS/Android)	🖥️ Workstation (Ubuntu)
Encryption	Device-level (enforced by MDM)	LUKS full disk (verified at boot)
Screen Lock	5 min timeout, biometric/PIN	5 min timeout, password required
Updates	Auto-update encouraged, 30-day max lag	Unattended security updates
Malware Protection	OS-native + app sandboxing	ClamAV scanning
Remote Wipe	AWS WorkMail remote wipe capability	Data backed up to AWS, manual wipe if lost

3️⃣ App Management & Containerization

Principle: Control what apps can access what data.

Mobile App Strategy

📧 Email Containerization: Corporate email accessed only through AWS WorkMail-approved apps
- iOS: Native Mail app with MDM profile
- Android: Approved email clients with WorkMail integration
🔐 Data Separation: Corporate data containerized, personal data unaffected by wipe
🚫 Blacklisted Apps: Known malicious apps blocked (via OS mechanisms and education)
✅ Approved Apps for Business Use:
- Email clients (Native Mail, WorkMail-approved clients)
- Authenticator apps (Google Authenticator, Authy)
- AWS Console mobile app (with MFA)
- GitHub mobile app (with SSH keys)
- Business communication (Signal for secure messaging)

Workstation App Management

📦 Package Management: Official Ubuntu repositories + verified PPAs only
🔐 Development Tools: IDE and tools from official sources (JetBrains, VS Code official repos)
🛡️ Security Tools: Security scanning and monitoring tools from verified sources
📝 Installation Control: All software installations documented in Change Management

4️⃣ Remote Wipe Capability

Principle: Lost device? Delete corporate data.

Mobile Device Wipe Procedures

Selective Wipe (Corporate Data Only):

Access AWS WorkMail admin console
Select compromised device
Initiate selective wipe (removes email, contacts, calendar only)
Verify wipe completion
Document incident in Incident Response Plan
Update Asset Register status

Full Device Wipe (Entire Device):

Available via AWS WorkMail for complete device reset
Used when device theft suspected or higher-risk scenario
Personal data loss acceptable in critical security scenarios

Workstation Wipe Procedures

Remote Scenario (Device Accessible):

Initiate remote connection (if available)
Verify backups are current in AWS S3
Execute secure deletion of critical data
Disable all authentication credentials
Document in incident log

Lost/Stolen Scenario:

Immediately disable all credentials (AWS, GitHub, Google)
Report to authorities if theft suspected
Verify LUKS encryption prevents data access
Monitor for unauthorized access attempts
Procure replacement device and restore from backups

Wipe Decision Matrix

🎯 Scenario	📱 Mobile Action	🖥️ Workstation Action	⏱️ Response Time
Device Lost - Likely Recoverable	Selective wipe + monitoring	Disable credentials + monitoring	⚡ Immediate (1 hour)
Device Stolen - High Risk	Full device wipe	Credential disable + report theft	⚡ Immediate (30 min)
Suspected Compromise	Full device wipe + forensics	Full credential rotation + analysis	⚡ Critical (15 min)
Device Retirement	Factory reset (manual)	Secure wipe + physical destruction	🟡 Planned (24 hours)

5️⃣ Monitoring & Compliance

Principle: Track compliance, detect anomalies.

Mobile Device Monitoring

📊 MDM Console: AWS WorkMail admin console reviewed monthly
✅ Compliance Checks:
- Device encryption status
- OS version current within 30-day window
- No jailbreak/root detection
- Policy violations (screen lock disabled, etc.)
🚨 Alerts: Email notifications for:
- MDM policy violations
- Failed login attempts
- Device enrollment changes
- Suspicious activity patterns

Workstation Monitoring

🔍 Security Logging:
- System logs reviewed weekly via journalctl
- Failed authentication attempts monitored
- Package installation/updates tracked
- Network connection logs reviewed
📊 Compliance Verification:
- LUKS encryption status: Verified at every boot
- Firewall status: Monthly UFW status check
- Update status: Weekly package update review
- Disk space: Automated monitoring for backup capacity

Monitoring Schedule
