What this checklist covers

This checklist covers 12 security measures every enterprise IT team should have in place for their mobile device fleet:

• Device security policies and user training
• Screen lock, password, and encryption enforcement
• Offline lockouts and MDM compliance automation
• Remote lock, remote wipe, and geofencing
• Network access controls and app security
• Security audits, patch management, and device lifecycle tracking

‍

Key Takeaways

• Strong mobile security requires policies, user training, and enforced protections like passwords and encryption
• Fast response tools like remote lock, wipe, and tracking are essential to reduce risk from lost or stolen devices
• Ongoing controls such as app restrictions, network security, and regular updates prevent vulnerabilities

‍

1. Establish a Mobile Device Security Policy

Why It’s Important: A clear security policy sets the foundation for strong device protection.

• Define Acceptable Use: Establish rules on business vs. personal use, app downloads, and network connections.

• Set Data Protection Guidelines:  Outline encryption, backup procedures, and device tracking policies.

• Require User Acknowledgment: Ensure employees, students, or staff agree to security policies before using devices.

Best Practice: Regularly review and update policies to address new threats and changing regulations.

‍

2. Train Employees & Students on Device Security

Why It’s Important: Human error is the biggest security risk—ongoing training ensures users follow best practices.

• Educate on Phishing & Social Engineering: Teach users to spot fake emails, texts, and malware-laden links.

• Enforce Safe Device Handling: Train users on preventing loss, theft, and unauthorized access.

• Conduct Recurring Training: Cyber threats evolve, so security awareness should too.

Best Practice: Include real-world attack examples in training sessions to reinforce learning.

‍

3. Enforce Strong Screen Lock & Password Policies

Why It’s Important: 81% of breaches are caused by weak or stolen passwords.

• Require Complex Passwords: At least 12 characters, mixing letters, numbers, and symbols.

• Enable Automatic Locking: Set devices to lock after 5 minutes of inactivity to prevent unauthorized access.

• Use Biometric Authentication: Encourage fingerprint or facial recognition for added security.

Best Practice: Enforce regular password updates every 60–90 days to maintain security.

‍

4. Enable Full-Device Encryption

Why It’s Important: Encryption keeps stolen data unreadable without proper authentication.

• Enable Full-Disk Encryption: Prevents unauthorized access to stored data.

• Secure Removable Storage: Ensure USB drives and SD cards follow encryption standards.

• Enforce Encryption via MDM: Centrally manage encryption settings for all devices.

Best Practice: Use 256-bit AES encryption, the industry standard for securing sensitive data.

‍

5. Enforce Offline Lockouts & Security Policies

Why It’s Important: A missing device shouldn’t remain usable indefinitely.

• Set Automatic Lockouts: Devices should lock if they don’t check in for 24 hours.

• Block Unauthorized Modifications:  Prevent jailbreaking, unauthorized app installs, or security setting changes.

• Ensure MDM Enforces Compliance: Keep devices secure even when disconnected from the network.

Best Practice: Configure MDM alerts to notify IT when a device goes rogue or is inactive for too long.

‍

6. Automate Remote Lock & Wipe Capabilities

Why It’s Important: The longer a lost device remains unsecured, the higher the risk.

• Remotely Lock Devices: Prevent unauthorized access instantly.

• Wipe Data if a Device Is Unrecoverable: Ensure sensitive information doesn’t fall into the wrong hands.

• Revoke Access to Business Accounts: Disable logins for email, cloud storage, and corporate apps.

Best Practice: Set automated remote wipe policies for devices that go missing beyond a set timeframe.

‍

7. Enable Location Tracking & Geofencing

Why It’s Important: The faster you locate a lost device, the lower the cost of replacement and security risks.

• Track Device Locations in Real Time: Maintain full visibility over company-owned devices.

• Set Geofencing Alerts: Get notified if a device moves outside approved locations.

• Speed Up Recovery Efforts: Improve retrieval rates and reduce financial loss.

Best Practice: Set restricted zones for devices, triggering alerts if they enter high-risk locations.

For Chromebook fleets, Google Admin Console shows last-known location but does not provide real-time tracking or geofencing alerts natively. See how Senturo layers real-time tracking on top of Google Admin Console for K-12 districts.

‍

8. Use a VPN & Secure Network Access

Why It’s Important: Unsecured networks are a hacker’s playground.

• Require VPN Use for Remote Access: Encrypt data traveling over public networks.

• Block High-Risk Wi-Fi Networks: Prevent users from connecting to untrusted hotspots.

• Monitor SSID & IP Address Activity: Restrict device access to approved networks only.

Best Practice: Use always-on VPNs for company devices to enforce encryption at all times.

‍

9. Implement App Security Controls

Why It’s Important: Malicious apps can steal data, install spyware, or open backdoors.

• Limit App Permissions: Ensure apps only have access to what they need.

• Block Unauthorized Downloads: Prevent sideloading apps from unofficial sources.

• Use App Whitelisting: Allow only approved apps on company devices.

Best Practice: Regularly audit installed apps to remove unnecessary or high-risk applications.

‍

10. Perform Regular Security Audits & Updates

Why It’s Important: Unpatched vulnerabilities are consistently among the leading causes of successful cyberattacks. CISA's Known Exploited Vulnerabilities catalog documents the most actively targeted gaps.

• Schedule Routine Security Audits: Identify and fix security gaps proactively.

• Enforce Software & Patch Updates: Ensure OS and apps receive updates as soon as they’re available.

• Monitor Compliance Regularly: Use reporting tools to track security posture.

Best Practice: Automate patch management to avoid gaps in protection.

‍

11. Develop a Lost & Stolen Device Response Plan

Why It’s Important: A fast response reduces security risks, downtime, and replacement costs.

Frequently Asked Questions

What are the most important mobile device security measures for enterprise IT?

The highest-impact measures are remote lock and wipe capability, full-device encryption enforced via MDM, real-time location tracking with geofencing, and a documented lost device response plan. These four areas address both immediate incident response and ongoing compliance enforcement.

How do I remotely wipe a lost device?

Remote wipe depends on the OS and MDM. For iOS and macOS, Jamf Pro and Intune both support remote wipe natively. For Windows laptops, Intune remote wipe works but requires devices to check in first -- for immediate action, a third-party agent like Senturo provides faster response. For Chrome OS, Google Admin Console supports remote deprovision. For Android, both Intune and Google Admin support remote factory reset.

What is geofencing for device security?

Geofencing creates a virtual boundary around a physical location. When a device crosses that boundary, an automated action triggers -typically an alert to IT, a lock command, or a Missing Mode activation. Enterprise IT teams use geofencing to enforce policies like keeping devices within school buildings or office campuses, and to detect when a device has been removed without authorization.

Does this checklist apply to Chromebooks?

Yes. Items 1 through 5 and items 9 through 12 apply directly. For items 6 and 7, note that Google Admin Console's native remote lock and location tools are limited compared to other platforms -Chromebook fleets benefit from a third-party tracking layer for real-time visibility and automated geofence responses.

What compliance frameworks does this checklist support?

For K-12 districts: FERPA (student data privacy) and CIPA (internet safety requirements). For healthcare: HIPAA. For corporate and government fleets: SOC 2 and ISO 27001. The specific controls most relevant to each framework are items 1 (policy), 4 (encryption), 5 (access control), 10 (audit and patch management), and 12 (lifecycle management).
