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. Refer to 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
Checks: C-64170r953768_chk

The DOD warning banner can be displayed using the following method (required text is found in the Vulnerability Discussion): Place the DOD warning banner in the user agreement signed by each Samsung Android device user (preferred method). Note: It is not possible for the EMM to force a warning banner be placed on the device screen when using "work profile for employee-owned devices (BYOD)" deployment mode. Review the signed user agreements for several Samsung Android device users and verify the agreement includes the required DOD warning banner text. If the required warning banner text is not on all signed user agreements reviewed, this is a finding.

Fix: F-64077r953769_fix

Configure the DOD warning banner by either of the following methods (required text is found in the Vulnerability Description): Place the DOD warning banner in the user agreement signed by each Samsung Android device user (preferred method).

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. Therefore, disallowing repeating or sequential characters increases password strength and decreases risk. SFR ID: FMT_SMF_EXT.1.1 #1b
Checks: C-64171r950900_chk

Review the configuration to determine if the Samsung Android devices' Work Environment is disallowing passwords containing more than four repeating or sequential characters. This validation procedure is performed on both the management tool and the Samsung Android device. On the management tool, in the device password policies, verify "minimum password quality" is set to "Numeric(Complex)" or better. On the Samsung Android device, confirm if the user has "One Lock" enabled (Settings >> Security and privacy >> More security settings >> Work profile security >> Use one lock). If "One Lock" is enabled: 1. Open Settings >> Lock screen >> Screen lock type. 2. Enter current password. 3. Tap "PIN". 4. Verify that PINs with more than four repeating or sequential numbers are not accepted. If "One Lock" is disabled: 1. Open Settings >> Security and privacy >> More security settings >> Work profile security >> Work profile lock type. 2. Enter current password. 3. Tap "PIN". 4. Verify that PINs with more than four repeating or sequential numbers are not accepted. If on the management tool "minimum password quality" is not set to "Numeric(Complex)" or better, or on the Samsung Android device a password with more than four repeating or sequential numbers is accepted, this is a finding.

Fix: F-64078r950901_fix

Configure the Samsung Android devices to disallow passwords containing more than four repeating or sequential characters. On the management tool, in the device password policies, set "minimum password quality" to "Numeric(Complex)" or better. If the management tool does not support "Numeric(Complex)" but does support "Numeric", Knox Platform for Enterprise (KPE) can be used to achieve STIG compliance. In this case, configure this policy with value "Numeric" and use an additional KPE policy (innately by the management tool or via KSP) "Maximum Numeric Sequence Length" with value "4".

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 complete 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-64172r950903_chk

Review the configuration to determine if the Samsung Android devices' Work Environment is enforcing a minimum password length of six characters. This validation procedure is performed on both the management tool and the Samsung Android device. On the management tool, in the Work Environment password policies, verify "minimum password length" is set to "6". On the Samsung Android device, confirm if the user has "One Lock" enabled (Settings >> Security and privacy >> More security settings >> Work profile security >> Use one lock). If "One Lock" is enabled: 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 "One Lock" is disabled: 1. Open Settings >> Security and privacy >> More security settings >> Work profile security >> Work profile 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 "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.

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 fewer attempts 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
Checks: C-64173r950906_chk

Review the configuration to determine if the Samsung Android devices' Work Environment is allowing only 10 or fewer consecutive failed authentication attempts. This validation procedure is performed on both the management tool and the Samsung Android device. On the management tool, in the device password policies, verify "max password failures for local wipe" is set to "10" attempts or less. On the Samsung Android device, confirm if the user has "One Lock" enabled (Settings >> Security and privacy >> More security settings >> Work profile security >> Use one lock). If "One Lock" is enabled: 1. Lock the device. 2. Make attempts to unlock the Device with incorrect PIN and validate that the device reports that if you do not enter the correct PIN within the next few attempts that a wipe will occur. If "One Lock" is disabled: 1. Wait for the Work profile to Lock (determined by Auto lock work profile configuration) - or reboot the Device. 2. Attempt to unlock the Work profile with an incorrect PIN and validate that the device reports "9" or less attempts left. If on the management tool "max password failures for local wipe" is not set to "10" attempts or less, or on the Samsung Android device - after making incorrect PIN entry attempts - it does not report that the device will wipe, this is a finding.

Fix: F-64080r950907_fix

Configure the Samsung Android devices to allow only 10 or fewer consecutive failed authentication attempts. On the management tool, in the device password policies, set "max password failures for local wipe" to "10" attempts or fewer. A device password must be set for "max password failures for local wipe" to become active.

The biometric factor can be used to authenticate the user to unlock the mobile device. Unapproved/evaluated biometric mechanisms could allow unauthorized users to have access to DOD sensitive data if compromised. By not permitting the use of unapproved/evaluated biometric authentication mechanisms, this risk is mitigated. SFR ID: FMT_SMF_EXT.1.1 #22, FIA_UAU.5.1
Checks: C-64175r953770_chk

Note: This requirement is not applicable for specific biometric authentication factors included in the product's Common Criteria evaluation. Review the configuration to determine if the Samsung Android devices' Work Environment is disabling Face Recognition. This validation procedure is performed on both the management tool and the Samsung Android device. Face recognition is not a feature available for unlocking the Work profile unless "One Lock" is used. Otherwise, on the management tool, in the Work Environment restrictions, verify that "Face" is set to "Disable". On the Samsung Android device, confirm if the user has "One Lock" enabled (Settings >> Security and privacy >> More security settings >> Work profile security >> Use one lock). If "One Lock" is enabled: 1. Open Settings >> Lock screen >> Screen lock type. 2. Enter current password. 3. Verify that "Face" is disabled and cannot be enabled. The disablement of Face cannot be verified while "One Lock" is disabled, as they are not an available feature for Work profiles. To verify, the Admin would need to temporarily enable "One Lock" for the purpose of testing only and follow the above instruction. After testing, the User would have to reset their Work profile password when "One Lock" was turned off again. If on the management tool "Face" is not set to "Disable", or on the Samsung Android device "Face" can be enabled, this is a finding.

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. SFR ID: FMT_SMF_EXT.1.1 #2a
Checks: C-64176r953771_chk

Review the configuration to determine if the Samsung Android devices' Work Environment is disabling Trust Agents. This validation procedure is performed on both the management tool and the Samsung Android device. On the management tool, in the device restrictions, verify that "Trust Agents" are set to "Disable". On the Samsung Android device, confirm if the user has "One Lock" enabled (Settings >> Security and privacy >> More security settings >> Work profile security >> Use one lock). If "One Lock" is enabled: 1. Open Settings >> Security and privacy >> More security settings >> Trust agents. 2. Verify that all listed Trust Agents are disabled and cannot be enabled. The disablement of Trust Agents cannot be verified while "One Lock" is disabled, as they are not an available feature for Work profiles. To verify, the Admin would need to temporarily enable "One Lock" for the purpose of testing only and follow the above instruction. After testing, the User would have to reset their Work profile password when "One Lock" was turned off again. If on the management tool "Trust Agents" are not set to "Disable", or on the Samsung Android device a "Trust Agent" can be enabled, this is a finding. Note: If the management tool has been correctly configured but a Trust Agent is still enabled, configure the "List of approved apps listed in managed Google Play" to disable it; refer to KNOX-14-710190. Exception: Trust Agents may be used if the Authorizing Official (AO) allows a screen lock timeout after four hours (or more) of inactivity. This may be applicable to tactical use case.

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 preinstalled applications. Core application: Any application integrated into the OS by the OS or MD vendors. Preinstalled application: Additional noncore 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 preinstalled 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 preinstalled applications.

Many mobile devices display notifications on the lock screen so that users can obtain relevant information in a timely manner without having to frequently unlock the phone to determine if there are new notifications. However, in many cases, these notifications can contain sensitive information. When they are available on the lock screen, an adversary can see them merely by being in close physical proximity to the device. Configuring the MOS to not send notifications to the lock screen mitigates this risk. SFR ID: FMT_SMF_EXT.1.1 #18

Backups to remote systems (including cloud backup) can leave data vulnerable to breach on the external systems, which often offer less protection than the MOS. 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. The Data Sync Framework allows apps to synchronize data between the mobile device and other web based services. This uses accounts for services the user has added to the mobile device. Preventing the user from adding accounts to the device mitigates this risk. For BYOD Work profile data cannot be backed up remotely via Backup Services. Work profile data could be backed up thru adding an account to an app that supports the data sync framework, however, this is mitigated by preventing adding any accounts to the Work profile.

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. SFR ID: FMT_SMF_EXT.1.1 #42, FDP_ACF_EXT.1.2
