Vuln Discussion

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. Passwords that contain repeating or sequential characters are significantly easier to guess than those that do not contain repeating or sequential characters.

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.

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>

<key>maxInactivity</key>

<integer>5</integer>"

Here, 5 + 5 = 10; so this meets the requirement.

On the iPhone and iPad:

1. Open the Settings app.

2. Tap "General".

3. Tap "VPN & Device Management".

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 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.

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 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.

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.

Many mobile devices display notifications on the lock screen so 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.

Vuln Discussion

Data on mobile devices is protected by numerous mechanisms, including user authentication, access control, and cryptography. When the data is backed up to an external system (either locally connected or cloud based), many if not all of these mechanisms are no longer present. This leaves the backed-up data vulnerable to attack. Disabling backup to external systems mitigates this risk.

Vuln Discussion

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.

Check Content

Review configuration settings to confirm "Allow documents from unmanaged apps in managed apps" 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 iOS management tool, verify "Allow documents from unmanaged apps in managed apps" is unchecked.

On the iOS device:

1. Open the Settings app.

2. Tap "General".

3. Tap "VPN & Device Management".

4. Tap the Configuration Profile from the iOS management tool containing the restrictions policy.

5. Tap "Restrictions".

6. Verify "Opening documents from unmanaged to managed apps not allowed" is listed.

If "Allow documents from unmanaged apps in managed apps" is checked in the iOS management tool or the restrictions policy on the iPhone and iPad does not list "Opening documents from unmanaged to managed apps not allowed", this is a finding.
