Level 2


Description:

A mobile device is a computing device that has a small form factor such that it can easily be carried by a single individual; is designed to operate without a physical connection (e.g., wirelessly transmit or receive information); possesses local, non-removable or removable data storage; and includes a self-contained power source. Mobile devices may also include voice communication capabilities, on-board sensors that allow the device to capture information, or built-in features for synchronizing local data with remote locations. Examples of mobile devices include smartphones, e-readers, and tablets.  Due to the large variety of mobile devices with different technical characteristics and capabilities, organizational restrictions may vary for the different types of devices. Usage restrictions and implementation guidance for mobile devices include: device identification and authentication; configuration management; implementation of mandatory protective software (e.g., malicious code detection, firewall); scanning devices for malicious code; updating virus protection software; scanning for critical software updates and patches; conducting primary operating system (and possibly other resident software) integrity checks; and disabling unnecessary hardware (e.g., wireless, infrared). The need to provide adequate security for mobile devices goes beyond this requirement. Many controls for mobile devices are reflected in other CUI security requirements.  [SP 800-124] provides guidance on mobile device security.

What needs to be answered:

Is there a policy on the use of mobile devices? Can mobile devices connect to the network? Is usage monitored and controlled? 


Checks for AWS

  • Control Connection of Mobile Devices
    Description: This check ensures that the connection of mobile devices to the system is controlled and governed by organizational policies and restrictions. Mobile devices include smartphones, e-readers, tablets, and other computing devices with wireless capabilities.
  • Implement Device Identification and Authentication
    Description: This check verifies that mobile devices connecting to the system undergo device identification and authentication processes to ensure authorized access and prevent unauthorized devices from connecting.
  • Enforce Configuration Management for Mobile Devices
    Description: This check confirms that configuration management practices are implemented for mobile devices, ensuring that devices are properly configured with appropriate security settings and policies.
  • Enable Protective Software for Mobile Devices
    Description: This check ensures that mandatory protective software, such as malicious code detection and firewalls, is implemented on mobile devices to enhance their security against threats.          


Checks for Azure

  • Define and Enforce Mobile Device Usage Policy:
    Description: This policy check ensures that a defined mobile device usage policy is in place and enforced. It verifies that there are documented policies, standards, and procedures for the use of mobile devices within the organization. The policy should address device identification and authentication, configuration management, protective software, scanning for malicious code, virus protection software updates, critical software updates and patches, primary operating system integrity checks, and disabling unnecessary hardware. This policy check aims to ensure that mobile device usage is controlled and aligned with security requirements.
  • Control Connection of Mobile Devices:
    Description: This check ensures that the connection of mobile devices to the network is controlled and governed by organizational policies and restrictions. It verifies that mobile devices, including smartphones, e-readers, tablets, and other wireless-capable computing devices, comply with the defined usage restrictions and configuration/connection requirements. By controlling the connection of mobile devices, unauthorized access and potential risks to organizational systems are reduced.
  • Implement Mobile Device Identification and Authentication:
    Description: This check verifies that mobile devices connecting to the system undergo device identification and authentication processes. It ensures that authorized devices are granted access, while unauthorized or unauthenticated devices are prevented from connecting. Implementing device identification and authentication enhances the security of mobile device access to organizational systems.
  • Enforce Configuration Management for Mobile Devices:
    Description: This policy check confirms that configuration management practices are implemented for mobile devices. It ensures that mobile devices are properly configured with appropriate security settings and policies in line with organizational requirements. Enforcing configuration management for mobile devices helps reduce vulnerabilities and ensures consistent security posture across the device fleet.
  • Enable Protective Software for Mobile Devices:
    Description: This check ensures that mandatory protective software, such as malicious code detection and firewalls, is implemented on mobile devices. It verifies that mobile devices are equipped with the necessary protective measures to enhance their security against potential threats. Enabling protective software on mobile devices helps mitigate risks and protect sensitive data.
