Password strength is a measure of the effectiveness of a password in resisting guessing and brute force attacks. The ability to crack a password is a function of how many attempts an adversary is permitted, how quickly an adversary can do each attempt, and the size of the password space. The longer the minimum length of the password is, the larger the password space. Having a too-short minimum password length significantly reduces password strength, increasing the chance of password compromise and resulting in device and data compromise.

Password strength is a measure of the effectiveness of a password in resisting guessing and brute force attacks. Passwords that contain repeating or sequential characters are significantly easier to guess than those that do not contain repeating or sequential characters. Therefore, disallowing repeating or sequential characters increases password strength and decreases risk.

The screen lock timeout helps protect the device from unauthorized access. Devices without a screen lock timeout provide an opportunity for adversaries who gain physical access to the mobile device through loss, theft, etc. Such devices are much more likely to be in an unlocked state when acquired by an adversary, thus granting immediate access to the data on the mobile device and possibly access to DoD networks.

The screen lock timeout must be set to a value that helps protect the device from unauthorized access. Having a too-long timeout would increase the window of opportunity for adversaries who gain physical access to the mobile device through loss, theft, etc. Such devices are much more likely to be in an unlocked state when acquired by an adversary, thus granting immediate access to the data on the mobile device. The maximum timeout period of 15 minutes has been selected to balance functionality and security; shorter timeout periods may be appropriate depending on the risks posed to the mobile device.

The more attempts an adversary has to guess a password, the more likely the adversary will enter the correct password and gain access to resources on the device. Setting a limit on the number of attempts mitigates this risk. Setting the limit at 10 or less gives authorized users the ability to make a few mistakes when entering the password but still provides adequate protection against dictionary or brute force attacks on the password.

The application whitelist, in addition to controlling the installation of applications on the mobile device (MD), must control user access/execution of all core and preinstalled applications, or the MD must provide an alternate method of restricting user access/execution to core and pre-installed applications.
Core application: Any application integrated into the OS by the OS or MD vendors.
Pre-installed application: Additional non-core applications included in the operating system (OS) build by the OS vendor, MD vendor, or wireless carrier.
Requiring all authorized applications to be in an application whitelist prevents the execution of any applications (e.g., unauthorized, malicious) that are not part of the whitelist. Failure to configure an application whitelist properly could allow unauthorized and malicious applications to be downloaded, installed, and executed on the mobile device, causing a compromise of DoD data accessible by these applications.

Trust agents allow a user to unlock a mobile device without entering a passcode when the mobile device is, for example, connected to a user-selected Bluetooth device or in a user-selected location. If compromised, this technology would allow unauthorized users to have access to DoD sensitive data. Not permitting the use of non-password authentication mechanisms forces users to use passcodes that meet DoD passcode requirements.

Android Pie is required to display the DoD-approved system use notification message or banner before granting access to the system that provides privacy and security notices consistent with applicable federal laws, Executive Orders, directives, policies, regulations, standards, and guidance. Required banners help ensure that DoD can audit and monitor the activities of mobile device users without legal restriction.
System use notification messages can be displayed when individuals first access or unlock the mobile device. The banner must be implemented as a "click-through" banner at device unlock (to the extent permitted by the operating system). A "click-through" banner prevents further activity on the information system unless and until the user executes a positive action to manifest agreement by clicking on a box indicating "OK".
The approved DoD text must be used exactly as required in the KS referenced in DoDI 8500.01. For devices accommodating banners of 1300 characters, the banner text is:
You are accessing a U.S. Government (USG) Information System (IS) that is provided for USG-authorized use only.

-At any time, the USG may inspect and seize data stored on this IS.

Such communications and work product are private and confidential. See User Agreement for details.
For devices with severe character limitations, the banner text is:

Data on mobile devices is protected by numerous mechanisms, including user authentication, access control, and cryptography. When the data is backed up to an external system (either locally connected or cloud-based), many if not all of these mechanisms are no longer present.

Backups to remote systems (including cloud backup) can leave data vulnerable to breach on the external systems, which often offer less protection than the Android device. Where the remote backup involves a cloud-based solution, the backup capability is often used to synchronize data across multiple devices. In this case, DoD devices may synchronize DoD sensitive information to a user's personal device or other unauthorized computers that are vulnerable to breach. Disallowing remote backup mitigates this risk.

The security posture of Google devices requires the device user to configure several required policy rules on their device. User-Based Enforcement (UBE) is required for these controls. In addition, if the Authorizing Official (AO) has approved the use of an unmanaged personal space, the user must receive training on risks. If a user is not aware of their responsibilities and does not comply with UBE requirements, the security posture of the mobile device may become compromised and DoD sensitive data may become compromised.

Wi-Fi Sharing is an optional configuration of Wi-Fi Tethering/Mobile Hotspot, which allows the device to share its Wi-Fi connection with other wirelessly connected devices instead of its mobile (cellular) connection.
Wi-Fi Sharing grants the "other" device access to a corporate Wi-Fi network and may possibly bypass the network access control mechanisms. This risk can be partially mitigated by requiring the use of a preshared key for personal hotspots.
