The System Administrator must have the capability to configure VPN access to meet organization-specific policies based on mission needs. Otherwise, a user could inadvertently or maliciously set up a VPN and connect to a network that poses unacceptable risk to DoD information systems. An adversary could exploit vulnerabilities created by the weaker configuration to compromise DoD sensitive information. SFR ID: FMT_SMF_EXT.1.1 #3

Checks: C-54354r801846_chk

Review the list of unmanaged apps installed on the iPhone and iPad and determine if any third-party VPN clients are installed. If so, verify the VPN app is not configured with a DoD network (work) VPN profile. This validation procedure is performed on the iOS device only. On the iPhone and iPad: 1. Open the Settings app. 2. Tap "General". 3. Tap the "VPN and Device Management" line and determine if any "Personal VPN" exists. 4. If not, the requirement has been met. 5. If there are personal VPNs, open each VPN app. Review the list of VPN profiles configured on the VPN client. 6. Verify there are no DoD network VPN profiles configured on the VPN client. If any third-party unmanaged VPN apps are installed (personal VPN) and they have a DoD network VPN profile configured on the client, this is a finding. Note: This setting cannot be managed by the MDM administrator and is a User-Based Enforcement (UBE) requirement.

Fix: F-54308r801847_fix

If a third-party unmanaged VPN app is installed on the iOS 15 device, do not configure the VPN app with a DoD network VPN profile.

If a user is able to configure the security setting, the user could inadvertently or maliciously set it to a value that poses unacceptable risk to DoD information systems. An adversary could exploit vulnerabilities created by the weaker configuration to compromise DoD sensitive information. SFR ID: FMT_MOF_EXT.1.2 #40

Checks: C-54355r801849_chk

Note: This requirement is not applicable if the Authorizing Official (AO) has approved users' full access to the Apple App Store for downloading unmanaged (personal) apps and syncing personal data on the device with personal cloud data storage accounts. The site must have an AO-signed document showing the AO has assumed the risk for users' full access to the Apple App Store. Review configuration settings to confirm iCloud Backup is disabled. This check procedure is performed on both the Apple iOS/iPadOS management tool and the iPhone and iPad. Note: If an organization has multiple configuration profiles, the check procedure must be performed on the relevant configuration profiles applicable to the scope of the review. In the Apple iOS/iPadOS management tool, verify "Allow iCloud backup" is unchecked. Alternatively, verify the text "<key>allowCloudBackup</key> <false/>" appears in the configuration profile (.mobileconfig file). On the iPhone and iPad: 1. Open the Settings app. 2. Tap "General". 3. Tap "Profiles & Device Management" or "Profiles". 4. Tap the Configuration Profile from the iOS management tool containing the policy. 5. Tap "Restrictions". 6. Verify "iCloud backup not allowed".

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-54364r801876_chk

Review configuration settings to confirm the minimum passcode length is six or more characters. This procedure is performed in the Apple iOS/iPadOS management tool and on the iPhone and iPad. Note: If an organization has multiple configuration profiles, the check procedure must be performed on the relevant configuration profiles applicable to the scope of the review. In the Management tool, verify the "Minimum passcode length" value is set to six or greater. Alternatively, verify the text "<key>minLength</key> <integer>6</integer>" appears in the configuration profile (.mobileconfig file). It also is acceptable for the integer value to be greater than six. On the iPhone and iPad: 1. Open the Settings app. 2. Tap "General". 3. Tap "Profiles & Device Management" or "Profiles". 4. Tap the Configuration Profile from the Apple iOS/iPadOS management tool containing the password policy. 5. Tap "Restrictions". 6. Tap "Passcode". 7. Verify "Minimum length" is listed as "six or greater". If the "Minimum passcode length" is less than six characters in the iOS management tool, "<key>minLength</key> " has an integer value of less than six, or the password policy on the iPhone and iPad from the Apple iOS/iPadOS management tool does not list "Minimum length" of six or fewer, this is a finding.

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. SFR ID: FMT_SMF_EXT.1.1 #2a

Checks: C-54366r801882_chk

Review configuration settings to confirm the screen lock timeout is set to 15 minutes or less. This check procedure is performed on both the Apple iOS/iPadOS management tool and the iPhone and iPad. Note: If an organization has multiple configuration profiles, the check procedure must be performed on the relevant configuration profiles applicable to the scope of the review. In the management tool, verify the sum of the values assigned to "Maximum Auto-Lock time" and "Grace period for device lock" is between 1 and 15 minutes. Alternatively, locate the text "<key>maxGracePeriod</key>" and "<key>maxInactivity</key>" and ensure the sum of their integer value is between 1 and 15 in the configuration profile (.mobileconfig file). For example: "<key>maxGracePeriod</key> <integer>5</integer> <key>maxInactivity</key> <integer>5</integer>" Here, 5 + 5 = 10; this meets the requirement. On the iPhone and iPad: 1. Open the Settings app. 2. Tap "General". 3. Tap "Profiles & Device Management" or "Profiles". 4. Tap the Configuration Profile from the iOS management tool containing the password policy. 5. Tap "Restrictions". 6. Tap "Passcode". 7. Verify the sum of the "Max grace period" and "Max inactivity" values is less than 15 minutes. Note: On some iOS/iPadOS devices, it is not possible to have a sum of exactly 15. In these cases, the sum must be less than 15. A sum of 16 does not meet the requirement. On the management server, if the sum of the "Max grace period" and "Max inactivity" values is not between 1 and 15 minutes in the iOS/iPadOS management tool, or if the sum of the values assigned to "<key>maxGracePeriod</key>" and "<key>maxInactivity</key>" is not between 1 and 15 minutes in the configuration profile, or if on the iPhone/iPad, the sum of the values assigned to "Max grace period" and "Max inactivity" is not between 1 and 15 minutes, this is a finding.

Fix: F-54320r801883_fix

Install a configuration profile to lock the device display after 15 minutes (or less) of inactivity. This is done by setting "Maximum Auto-Lock time" and "Grace Period for device lock" so the sum of their values is between 1 and 15 minutes.

Review configuration settings to confirm the screen lock timeout is set to 15 minutes or less. This check procedure is performed on both the Apple iOS/iPadOS management tool and the iPhone and iPad. Note: If an organization has multiple configuration profiles, the check procedure must be performed on the relevant configuration profiles applicable to the scope of the review. In the management tool, verify the sum of the values assigned to "Maximum Auto-Lock time" and "Grace period for device lock" is between 1 and 15 minutes. Alternatively, locate the text "<key>maxGracePeriod</key>" and "<key>maxInactivity</key>" and ensure the sum of their integer value is between 1 and 15 in the configuration profile (.mobileconfig file). For example: "<key>maxGracePeriod</key> <integer>5</integer> <key>maxInactivity</key> <integer>5</integer>" Here, 5 + 5 = 10; this meets the requirement. On the iPhone and iPad: 1. Open the Settings app. 2. Tap "General". 3. Tap "Profiles & Device Management" or "Profiles". 4. Tap the Configuration Profile from the iOS management tool containing the password policy. 5. Tap "Restrictions". 6. Tap "Passcode". 7. Verify the sum of the "Max grace period" and "Max inactivity" values is less than 15 minutes. Note: On some iOS/iPadOS devices, it is not possible to have a sum of exactly 15. In these cases, the sum must be less than 15. A sum of 16 does not meet the requirement. On the management server, if the sum of the "Max grace period" and "Max inactivity" values is not between 1 and 15 minutes in the iOS/iPadOS management tool, or if the sum of the values assigned to "<key>maxGracePeriod</key>" and "<key>maxInactivity</key>" is not between 1 and 15 minutes in the configuration profile, or if on the iPhone/iPad, the sum of the values assigned to "Max grace period" and "Max inactivity" is not between 1 and 15 minutes, this is a finding.

Fix: F-54321r801886_fix

Install a configuration profile to lock the device display after 15 minutes (or less) of inactivity. This is done by setting "Maximum Auto-Lock time" and "Grace Period for device lock" so the sum of their values is between 1 and 15 minutes.

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.

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. 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; 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

Passwords provide a form of access control that prevents unauthorized individuals from accessing computing resources and sensitive data. Passwords may also be a source of entropy for generation of key encryption or data encryption keys. If a password is not required to access data, this data is accessible to any adversary who obtains physical possession of the device. Requiring that a password be successfully entered before the mobile device data is unencrypted mitigates this risk. Note: MDF PP v2.0 requires a Password Authentication Factor and requires management of its length and complexity. It leaves open whether the existence of a password is subject to management. This requirement addresses the configuration to require a password, which is critical to the cybersecurity posture of the device. SFR ID: FIA_UAU_EXT.1.1

Apple's Family Sharing service allows Apple iOS/iPadOS users to create a Family Group whose members have several shared capabilities, including the ability to lock, wipe, play a sound on, or locate the iPhone and iPads of other members. Each member of the group must be invited to the group and accept that invitation. A DoD user's iPhone and iPad may be inadvertently or maliciously wiped by another member of the Family Group. This poses a risk that the user could be without a mobile device for a period of time or lose sensitive information that has not been backed up to other storage media. Configuring iPhone and iPads so their associated Apple IDs are not members of Family Groups mitigates this risk. Note: If the site uses Apple's optional Device Enrollment Program (DEP), this control is available as a supervised MDM control. SFR ID: FMT_SMF_EXT.1.1 #47

Checks: C-54394r801966_chk

Review configuration settings to confirm Family Sharing is disabled. Note that this is a User Based Enforcement (UBE) control, which cannot be managed by an MDM server. This check procedure is performed on the iPhone and iPad. On the iPhone and iPad: 1. Open the Settings app. 2. At the top of the screen, if "Sign in to your iPhone" is listed, this requirement has been met. 3. If the user profile is signed into iCloud, tap the user name. 4. Tap "Family Sharing". 5. Verify no accounts are listed other than the "Organizer". Note: The iPhone and iPad must be connected to the internet to conduct this validation procedure. Otherwise, the device will display the notice "Family information is not available", in which case configuration compliance cannot be determined. If accounts (names or email addresses) are listed under "FAMILY MEMBERS" on the iPhone and iPad, this is a finding. Note: If the site has implemented DEP (not required), this setting can be managed via the MDM (supervised mode).

Sharing of location data is an operational security (OPSEC) risk because it potentially allows an adversary to determine a DoD user's location, movements, and patterns in those movements over time. An adversary could use this information to target the user or gather intelligence on the user's likely activities. Using commercial cloud services to store and handle location data could leave the data vulnerable to breach, particularly by sophisticated adversaries. Disabling the use of such services mitigates this risk. SFR ID: FMT_SMF_EXT.1.1 #47

Have all iPhone and iPad users complete training on the following topics. Users must acknowledge receipt of training via a signed User Agreement or similar written record. Training topics: - Operational security concerns introduced by unmanaged applications, including applications using global positioning system (GPS) tracking. - Must ensure no DoD data is saved in an unmanaged app or transmitted from a personal app (for example, from personal email). - If the Purebred key management app is used, users are responsible for maintaining positive control of their credentialed device at all times. The DoD PKI certificate policy requires subscribers to maintain positive control of the devices that contain private keys and report any loss of control so the credentials can be revoked. Upon device retirement, turn in, or reassignment, ensure a factory data reset is performed prior to device handoff. Follow mobility service provider decommissioning procedures as applicable. - How to configure the following UBE controls (users must configure the control) and other controls on the iPhone and iPad: **Remove Family Sharing **Disable Shared Location **Disable Wi-Fi Assist **Use AirPrint only with AO-approved printers and print servers (see the Multifunction Device and Network Printers STIG for requirements) **Turn off "Apps" under "AUTOMATIC DOWNLOADS" in the "iTunes & App Store" section of the Settings app on the iPhone and iPad **Secure use of Calendar Alarm **Do not configure a DoD network (work) VPN profile on any third-party unmanaged VPN app **Disable iPhone and iPad radios using controls under "Settings" instead of "Control Center" - AO guidance on acceptable use and restrictions, if any, on downloading and installing personal apps and data (music, photos, etc.).

When an iOS/iPadOS is not supervised, the DoD mobile service provider cannot control when new iOS/iPadOS updates are installed on site-managed devices. Most updates should be installed immediately to mitigate new security vulnerabilities, while some sites need to test each update prior to installation to ensure critical missions are not adversely impacted by the update. Several password and data protection controls can be implemented only when an Apple device is supervised. SFR ID: FMT_SMF_EXT.1.1 #47

Checks: C-54409r802011_chk

Note: If an organization has multiple configuration profiles, the check procedure must be performed on the relevant configuration profiles applicable to the scope of the review. In the iOS management tool, verify all managed Apple devices are supervised (verification procedure will vary by MDM product). Note: If the Apple device is not managed by an MDM and supervision is set up via Apple Configurator, this procedure is not applicable. On the iPhone and iPad: 1. Open the Settings app. 2. Verify a message similar to the following appears on the screen: "This iPad is supervised by (name of site DoD mobile service provider)." If site-managed iOS/iPadOS devices are not supervised, this is a finding.

Fix: F-54363r802040_fix

Use one of the following methods to supervise iOS and iPadOS devices managed by the DoD mobile service provider. Method 1: - Register all current and new iOS and iPadOS devices in the DoD mobile service provider's Device Enrollment Program (DEP)/Apple Business Manager (ABM) account. - Enable supervision of managed iOS/iPadOS devices in the MDM. Method 2: - Configure each iOS/iPadOS device using the Apple Configurator tool for Supervision. - This method is usually only appropriate when MDM management of the DoD Apple device is not appropriate or an older device cannot be registered in DEP/ABM.

Many software systems automatically send diagnostic data to the manufacturer or a third party. This data enables the developers to understand real-world field behavior and improve the product based on that information. Unfortunately, it can also reveal information about what DoD users are doing with the systems and what causes them to fail. An adversary embedded within the software development team or elsewhere could use the information acquired to breach mobile operating system security. Disabling automatic transfer of such information mitigates this risk. SFR ID: FMT_SMF_EXT.1.1 #47a

Checks: C-54411r802017_chk

Review configuration settings to confirm "Allow sending diagnostic and usage data to Apple" is disabled. This check procedure is performed on both the iOS management tool and the iOS device. Note: If an organization has multiple configuration profiles, the check procedure must be performed on the relevant configuration profiles applicable to the scope of the review. In the iOS management tool, verify "Allow sending diagnostic and usage data to Apple" is unchecked. Alternatively, verify the text "<key>allowDiagnosticSubmission</key><false/>" appears in the configuration profile (.mobileconfig file). On the Apple iOS device: 1. Open the Settings app. 2. Tap "General". 3. Tap "Profiles & Device Management" or "Profiles". 4. Tap the Configuration Profile from the iOS management tool containing the management policy. 5. Tap "Restrictions". 6.
