Android Device Hardening Guidelines

Introduction:

This document provides guidelines on how to securely and safely use Android devices from a cyber security and privacy perspective. As a company that values the security and privacy of our employees and information, it is crucial to adhere to these guidelines when using Android devices for work-related purposes.

1. Device Selection and Operating System
   • Choose devices from reputable manufacturers with a history of providing regular security updates.
   • Ensure the device is running the latest available Android operating system version, which includes the most up-to-date security patches.
2. Device Configuration and Security Settings
   • Enable full device encryption to protect the data stored on the device.
   • Set a strong, unique password or PIN for device access. Avoid using easily guessable patterns or biometrics (e.g., facial recognition) that may be less secure.
   • Enable automatic locking of the device after a short period of inactivity (1-2 minutes).
   • Disable USB debugging and developer options to prevent unauthorized access to the device.
   • Enable two-factor authentication (2FA) for work-related accounts and services.
3. Application Installation and Management
   • Only install applications from trusted sources, such as the Google Play Store or your company’s approved app repository.
   • Regularly update all installed applications to ensure the latest security patches and features are applied.
   • Limit the number of installed applications to those necessary for work purposes and avoid installing apps with excessive permissions.
   • Implement a mobile device management (MDM) solution to manage and enforce security policies across all company devices.
   • Remove applications that are no longer needed or in use.
4. Network Connectivity and Communication
   • Only connect to trusted Wi-Fi networks, and avoid using public Wi-Fi hotspots when handling sensitive information.
   • Utilize a virtual private network (VPN) when accessing company resources or transmitting sensitive data over public networks.
   • Disable Bluetooth when not in use to minimize potential attack vectors.
   • Use secure communication applications for work-related conversations and avoid sending sensitive information through SMS or unencrypted messaging platforms.
5. Data Handling and Storage
   • Avoid storing sensitive data on the device, and instead, use secure cloud storage or the company’s designated storage solution.
   • Regularly back up important data to mitigate potential data loss in case of device theft or compromise.
   • Implement remote wipe capabilities through the MDM solution to ensure data can be securely erased if the device is lost or stolen.
6. Incident Response and Reporting
   • In case of a lost or stolen device, immediately report the incident to the IT or Information Security department.
   • If you suspect a security breach, malware infection, or unauthorized access, promptly report the incident to the Information Security Team for investigation and remediation.
7. User Awareness and Training
   • Regularly attend security awareness training sessions to stay informed about the latest threats, best practices, and company policies related to Android device usage.
   • Encourage colleagues to adhere to these guidelines and promote a culture of security and privacy awareness.
     

Conclusion:

By following these hardening guidelines, company employees can securely and safely use Android devices for work purposes while minimizing the risk of cyber threats and privacy breaches. Regularly review and update these guidelines as necessary to adapt to the evolving threat landscape and maintain a robust security posture.
