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 device and data compromise. SFR ID: FMT_SMF_EXT.1.1 #1a
Checks: C-56306r820475_chk

Review Zebra Android 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 Android 11 device. On the EMM console: 1. Open "Password constraints". 2. Select "Personal Profile". 3. Open "Minimum password quality". 4. Check that "Numeric Complex", "Alphabetic, Alphanumeric", or "Complex" is selected. 5. Verify that "Minimum password length" is "6". On the Android 11 device, do the following: 1. Open Settings >> Security >> Screen lock. 2. Enter current password. 3. Tap "Password or PIN". 4. Verify Password length listed is at least "6". If the device password length is not set to six characters or more on EMM console or on the Android 11 device, this is a finding.

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 numeric (complex) setting allows the use of a numeric only keyboard for passwords and enforces the repeating or sequential characters limitation. SFR ID: FMT_SMF_EXT.1.1 #1b
Checks: C-56307r820478_chk

Review Zebra Android device configuration settings to determine if the mobile device is prohibiting passwords with more than four repeating or sequential characters. This validation procedure is performed on both the EMM Administration Console and the Android 11 device. On the EMM console, do the following: 1. Open "Password constraints". 2. Select "Personal Profile". 3. Verify that quality is set to "Numeric (Complex)". On the Android 11 device, do the following: 1. Open Settings >> Security >> Screen lock. 2. Enter current password. 3. Tap "Password". 4. Try to enter a new PIN or Password with repeating numbers or characters. 5. Verify Password complexity requirements are listed: Ascending, descending, or repeated sequence of digits is not allowed. If the EMM console device policy is set to a password with more than four repeating or sequential characters or on the Android 11 device, the device policy is set to a password with more than four repeating or sequential characters, this is a finding. Note: Alphabetic, Alphanumeric, and Complex are also acceptable selections, but these selections will cause the user to select a complex password, which is not required by the STIG.

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. SFR ID: FMT_SMF_EXT.1.1 #2c, FIA_AFL_EXT.1.5

The application allow list, in addition to controlling the installation of applications on the 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 OS build by the OS vendor, MD vendor, or wireless carrier. Requiring all authorized applications to be in an application allow list prevents the execution of any applications (e.g., unauthorized, malicious) that are not part of the allow list. Failure to configure an application allow list 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. The application allow list, in addition to controlling the installation of applications on the MD, must control user access/execution of all core applications (included in the OS by the OS vendor) and pre-installed applications (provided by the MD vendor and wireless carrier), or the MD must provide an alternate method of restricting user access/execution to core and pre-installed applications. SFR ID: FMT_SMF_EXT.1.1 #8b

The Zebra Android 11 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. 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. The administrator must configure the banner text exactly as written without any changes. SFR ID: FMT_SMF_EXT.1.1 #36

The autofill services allow the user to complete text inputs that could contain sensitive information, such as personally identifiable information (PII), without previous knowledge of the information. By allowing the use of autofill services, an adversary who learns a user's Zebra Android 11 device password, or who otherwise is able to unlock the device, may be able to further breach other systems by relying on the autofill services to provide information unknown to the adversary. By disabling the autofill services, the risk of an adversary gaining further information about the device's user or compromising other systems is significantly mitigated. Examples of apps that offer autofill services include Samsung Pass, Google, Dashlane, LastPass, and 1Password. SFR ID: FMT_SMF_EXT.1.1 #47
