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 perform each attempt, and the size of the password space. The longer the minimum length of the password, 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. SFRID: FMT_SMF.1.1 #1
Checks: C-71450r1031761_chk

Review managed Google Android 15 device configuration settings to determine if the mobile device is enforcing a minimum password length of six characters. This validation procedure is performed on both the EMM Administration Console and the managed Google Android 15 device. On the EMM console: COBO: 1. Open "Lock screen" settings. 2. Open "Password constraints". 3. Open "Minimum password quality". 4. Verify Numeric Complex, Alphabetic, Alphanumeric, or Complex is selected. 5. Open "Minimum password length". 6. Verify "6" is set for number of characters. COPE: 1. Open "Lock screen" settings. 2. Open "Password constraints". 3. Select "Personal Profile". 4.

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. SFRID: FMT_SMF.1.1 #2
Checks: C-71452r1031767_chk

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. SFRID: FMT_SMF.1.1 #2, FIA_AFL_EXT.1.5
Checks: C-71453r1033057_chk

Review managed Google Android 15 device configuration settings to determine if the mobile device has the maximum number of consecutive failed authentication attempts set at 10 or fewer.

Before granting access to the system, the mobile operating system is required to display the DOD-approved system use notification message or banner 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 Knowledge Service 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. By using this IS (which includes any device attached to this IS), you consent to the following conditions: -The USG routinely intercepts and monitors communications on this IS for purposes including, but not limited to, penetration testing, COMSEC monitoring, network operations and defense, personnel misconduct (PM), law enforcement (LE), and counterintelligence (CI) investigations. -At any time, the USG may inspect and seize data stored on this IS. -Communications using, or data stored on, this IS are not private, are subject to routine monitoring, interception, and search, and may be disclosed or used for any USG-authorized purpose. -This IS includes security measures (e.g., authentication and access controls) to protect USG interests--not for your personal benefit or privacy. -Notwithstanding the above, using this IS does not constitute consent to PM, LE or CI investigative searching or monitoring of the content of privileged communications, or work product, related to personal representation or services by attorneys, psychotherapists, or clergy, and their assistants. Such communications and work product are private and confidential. See User Agreement for details. For devices with severe character limitations, the banner text is: I've read & consent to terms in IS user agreem't.

App data sharing gives apps the ability to access the data of other apps for enhanced user functionality. However, sharing also poses a significant risk that unauthorized users or apps will obtain access to DOD sensitive information. To mitigate this risk, there are data sharing restrictions, primarily from sharing data from personal (unmanaged) apps and work (managed) apps. If a user is allowed to make exceptions to the data sharing restriction policy, the user could enable unauthorized sharing of data, leaving it vulnerable to breach. Limiting the granting of exceptions to either the Administrator or common application developer mitigates this risk. Copy/paste of data between applications in different application processes or groups of application processes is considered an exception to the access control policy and therefore, the Administrator must be able to enable/disable the feature. Other exceptions include allowing any data or application sharing between process groups. SFRID: FMT_SMF.1.1 #42, FDP_ACF_EXT.1.2

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. SFRID: FMT_SMF_EXT.1.1 / WLAN #3
Checks: C-71472r1031827_chk

Review device configuration settings to confirm Wi-Fi Sharing is disabled. Mobile Hotspot must be enabled to enable Wi-Fi Sharing.

Private Space is an Android feature that provides a separate encrypted container on the mobile device. Apps in Private Space show up in a separate container in the launcher and are hidden from the "Recents" view, notifications, settings, and other apps when the Private Space is locked. In addition, MDM server allow list or blocklist cannot control the installation of apps into Private Space. Malware and other unauthorized apps could be installed on a DOD mobile device, which could lead to the compromise of DOD sensitive information or to an attack on the DOD network.
