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.

Review the list of unmanaged apps installed on the iPhone and iPad and determine if any unmanaged 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 no DOD network VPN profiles are 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.

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.

Password strength is a measure of the effectiveness of a password in resisting guessing and brute force attacks.

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.

"<key>maxGracePeriod</key>

<key>maxInactivity</key>

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.

iOS-iPadOS 17 and later versions include a feature that allows the previous passcode to be valid for 72 hours after a passcode change. If the previous passcode has been compromised and the attacker has access to it and the Apple device, enterprise data and the enterprise network can be compromised. Currently there is no MDM control to force the old passcode to expire immediately after passcode change. The previous passcode will expire immediately after a passcode change if the MDM password history control is implemented.

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. Applications with the listed characteristics have features that can cause the compromise of sensitive DOD data or have features with no known application in the DOD environment.

Application note: 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 preinstalled applications.

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.

The administrator must configure the banner text exactly as written without any changes.

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 sensitive DOD 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.

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 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.

Ad Tracking refers to the advertisers' ability to categorize the device and spam the user with ads that are most relevant to the user's preferences. By not "Force limiting ad tracking", advertising companies are able to gather information about the user and device's browsing habits. If "Limit Ad Tracking" is not limited, a database of browsing habits of DOD devices can be gathered and stored under no supervision of the DOD.

The Apple iOS/iPadOS Mail app can be configured to support multiple email accounts concurrently. These email accounts are likely to involve content of varying degrees of sensitivity (e.g., both personal and enterprise messages). To prevent the unauthorized and undetected forwarding or moving of messages from one account to another, Mail ActiveSync Exchange accounts can be configured to block such behavior. While users may still send a message from the Exchange account to another account, these transactions must involve an Exchange server, enabling audit records of the transaction, filtering of mail content, and subsequent forensic analysis.

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 Automatic Device Enrollment, this control is available as a supervised MDM control.

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.

The AutoFill functionality in browsers and applications allows the user to complete a form that contains sensitive information, such as PII, without previous knowledge of the information. By allowing the use of the AutoFill functionality, an adversary who learns a user's iPhone and iPad passcode, or who otherwise is able to unlock the device, may be able to further breach other systems by relying on the AutoFill feature to provide information unknown to the adversary. By disabling the AutoFill functionality, the risk of an adversary gaining further information about the device's user or compromising other systems is significantly mitigated.

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.

Vuln Discussion

DOD root and intermediate PKI certificates are used to verify the authenticity of PKI certificates of users and web services. If the user is allowed to remove root and intermediate certificates, the user could allow an adversary to falsely sign a certificate in such a way that it could not be detected. Restricting the ability to remove DOD root and intermediate PKI certificates to the administrator mitigates this risk.

Auto Unlock allows an Apple Watch to automatically unlock an iPhone or Mac when in close proximity (not available for iPad). This feature allows the iPhone/Mac to be unlocked without the user entering the device passcode, which may lead to unauthorized users access to the iPhone/Mac and sensitive DOD data. This control is not applicable if the authorizing official (AO) has approved the use of Apple Watches.

Check Content

Determine if the site AO has approved the use of Apple Watch with DOD-owned iPhones. Look for a document showing approval. If not approved, review configuration settings to confirm "Allow Auto Unlock" is disabled. If approved, this requirement is not applicable.

This check procedure is performed on the device management tool.

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.
