Source Material Documentation 2. Information Technology Cyber Security information NIST SP 800-124r2: Guidelines for Managing the Security of Mobile Devices in the Enterprise
Overview
This document provides comprehensive guidelines for managing the security of mobile devices within an enterprise. It covers the entire lifecycle of mobile device management, including selection, deployment, maintenance, and disposal, while emphasizing the importance of protecting sensitive data accessed through mobile devices. Below are detailed sections highlighting key points from the document:
Executive Summary
- Modern Mobile Devices: These are powerful computing platforms capable of much more than basic communication functions. They handle sensitive data and need robust security measures.
- Security Challenges: The diversity and rapid evolution of mobile technology present unique security challenges, including increased malware and vulnerabilities.
- Key Recommendations:
- Conduct threat analyses.
- Employ enterprise mobility management (EMM), mobile threat defense (MTD), and mobile application vetting.
- Secure devices before deployment.
- Keep systems updated.
- Continuously monitor and maintain security.
Mobile Device Definition and Characteristics
- Definition: Portable computing devices with local storage, wireless communication, and self-contained power sources.
- Characteristics: Include rich operating systems, small form factors, cameras, sensors, and various communication mechanisms (WiFi, Bluetooth, NFC).
Threats to Mobile Devices
- Exploitation of Vulnerabilities: Errors in software can be exploited by attackers.
- Loss and Theft: Portability increases the risk of devices being lost or stolen.
- Supply Chain Vulnerabilities: Malicious components can be introduced during the supply chain process.
- Misconfiguration: Improper configurations can expose enterprise resources.
- Phishing: Attackers trick users into providing credentials through deceptive messages.
- Unauthorized Certificates: Malicious certificates can compromise device security.
- Untrusted Devices: Devices not properly secured by the enterprise pose risks.
- Wireless Eavesdropping: Communications over non-secure networks can be intercepted.
- Mobile Malware: Malicious applications can compromise data.
- Insecure Lock Screens: Weak lock screen configurations can lead to data breaches.
- User Privacy Violations: Unauthorized data collection can undermine user privacy.
- Data Loss via Synchronization: Synchronizing with untrusted systems can result in data breaches.
- Shadow IT: Unauthorized IT resources can introduce security risks.
Mobile Security Technologies
- Hardware-Backed Security: Dedicated hardware components for protecting sensitive data.
- Data Isolation: Mechanisms like encryption and sandboxing to protect data.
- Platform Management APIs: APIs for device management and security.
- VPN Support: Secure communication through virtual private networks.
- Authentication Mechanisms: Use of biometrics and other authentication methods to secure access.
Enterprise Mobile Security Technologies
- Enterprise Mobility Management (EMM): Comprehensive solution for managing and securing mobile devices.
- Policy Enforcement: Enforcing security policies on devices.
- User and Device Authentication: Managing authentication methods.
- Data Communication and Storage: Protecting data through encryption and secure storage.
- Mobile Application Management (MAM): Controls and manages apps on devices.
- Mobile Threat Defense (MTD): Detects and protects against mobile threats.
- Mobile App Vetting: Ensures apps are secure before deployment.
- Virtual Mobile Infrastructure (VMI): Hosts virtual mobile devices and apps on backend infrastructure.
Recommended Mitigations and Countermeasures
- EMM Technologies: Utilize EMM for comprehensive device management.
- Cybersecurity Practices: Follow best practices for securing mobile devices.
- Remote Wipe: Ability to remotely wipe data from compromised devices.
- Security-Focused Device Selection: Choose devices with robust security features.
- Secure Connections: Use secure connections for accessing enterprise resources.
- Software Updates: Regularly update operating systems and apps.
- Application Vetting: Thoroughly vet applications for security issues.
- User Education: Educate users about mobile security risks and practices.
Mobile Device Deployment Lifecycle
- Identify Mobile Requirements: Understand the needs and use cases for mobile devices.
- Perform Risk Assessment: Assess risks associated with mobile device usage.
- Implement Mobility Strategy: Deploy and integrate mobile technologies securely.
- Operate and Maintain: Regularly audit and maintain mobile device security.
- Dispose or Reuse Devices: Securely handle the end-of-life process for devices.
Conclusion
Managing the security of mobile devices in the enterprise is a complex task that requires a multi-faceted approach, incorporating robust security technologies, comprehensive management practices, and continuous monitoring and updates. By following the guidelines outlined in NIST SP 800-124r2, organizations can better protect their mobile devices and the sensitive data they handle.
