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-33943r592653_chk

Review Samsung 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 management tool Administration Console and the Samsung Android device. On the management tool: 1. Open the device password policies. 2. Verify "minimum password quality" is set to "Numeric" (or better). 3. Verify "minimum password length" is set to "6". NOTE: The following text is written assuming a password quality of "Numeric" or "Numeric (Complex)" has been configured. If a password quality of "Alphabetic" (or better) has been configured, substitute the text "PIN" with "Password" and "6 digits" with "6 characters". On the Samsung Android device: 1. Open Settings >> Lock screen >> Screen lock type. 2. Enter current password. 3. Tap "PIN". 4. Verify the text "PIN must contain at least", followed by a value of at least "6 digits", appears above the PIN entry. If on the management tool the "minimum password quality" is not set to "Numeric" (or better) and "minimum password length" is not set to "6", or on the Samsung Android device the text "PIN must contain at least" is followed by a value of less than "6 digits", 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. SFR ID: FMT_SMF_EXT.1.1 #1b
Checks: C-33944r592656_chk

This requirement is not applicable if the password quality is set to Numeric (complex) or better.

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

The application allowlist, 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 allowlist prevents the execution of any applications (e.g., unauthorized, malicious) that are not part of the allowlist. Failure to configure an application allowlist 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 allowlist, 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

Review the Samsung Android Work Environment configuration setting to determine if the mobile device has an application allowlist configured. Verify that all applications listed on the allowlist have been approved by the Approving Official (AO). This validation procedure is performed only on the management tool Administration Console. On the management tool, in the Work Environment KPE restrictions section, verify that only AO-approved apps are listed in the "app installation allowlist". If on the management tool the Work Environment "app installation allowlist" contains non-AO-approved apps, this is a finding.

Fix: F-33921r592669_fix

Configure Samsung Android Work Environment to use an application allowlist. The application allowlist does not control user access to/execution of all core and preinstalled applications, and guidance for doing so is covered in KNOX-10-009300. On the management tool, in the Work Environment KPE application section, add each AO-approved app to the "app installation allowlist". NOTE: Refer to the management tool documentation to determine the following: - If an application installation denylist is also required to be configured when enforcing an "app installation allowlist"; and - If the management tool supports adding apps to the "app installation allowlist" by package name and/or digital signature or supports a combination of the two.

The mobile operating system 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

Certificate-based security controls are dependent on the ability of the system to verify the validity of a certificate. If the MOS were to accept an invalid certificate, it could take unauthorized actions, resulting in unanticipated outcomes. At the same time, if the MOS were to disable functionality when it could not determine the validity of the certificate, this could result in a denial of service. Therefore, the ability to provide exceptions is appropriate to balance the tradeoff between security and functionality. Always accepting certificates when they cannot be determined to be valid is the most extreme exception policy and is not appropriate in the DoD context. Involving an Administrator or user in the exception decision mitigates this risk to some degree. SFR ID: FIA_X509_EXT_2.2

The USB host mode feature allows USB devices to connect to the device (e.g., USB flash drives, USB mouse, USB keyboard) using a micro USB to USB adapter cable. The USB host mode exception list allows selected USB devices to operate, while disallowing others, based on their USB device class. With some USB device classes, a user can copy sensitive DoD information to external USB storage unencrypted, resulting in compromise of DoD data. However, some USB device classes do not allow data to be copied, such as Human Interface Devices (HID). Disabling all USB devices except for HID mitigates the risk of compromising sensitive DoD data. This allows for DeX mode to be used, with a USB keyboard and mouse, without compromising DoD data. SFR ID: FMT_SMF_EXT.1.1 #47
