Check: AIOS-01-000006

Apple iOS 7 STIG: AIOS-01-000006 (in version v1 r2)

Title

Apple iOS must require a valid password be successfully entered before the mobile device data is unencrypted. (Cat II impact)

Discussion

Encryption is only effective if the decryption procedure is protected. If an adversary can easily access the private key (either directly or through a software application), sensitive DoD data is likely to be disclosed. Password protection is one method to reduce the likelihood of such an occurrence.

Check Content

This check procedure is performed on both the iOS Over-the-Air management tool and the iOS device. Note: If an organization has multiple configuration profiles, then the check procedure must be performed on the relevant configuration profiles applicable to the scope of the review. In the iOS Over-the-Air management tool, verify a passcode payload exists in the configuration profile. For example, in Mobile Iron Admin Portal: 1. Ask the MDM administrator to display the "POLICIES & CONFIGS". 2. Click or tap on the word "Policies". 3. Click or tap the policy name. 4. Expand "Details" under "Policy Details". 5. Verify "Password" is set to "Mandatory". Alternatively, verify the text "<key>PayloadDisplayName</key> <string>Passcode</string>" appears in the configuration profile (.mobileconfig file). On the iOS device: 1. Open the Settings app. 2. Tap "General". 3. Tap "Profiles". 4. Verify the password policy from the iOS Over-the-Air management tool is present. If "Password" is set to "Optional" in the iOS Over-the-Air management tool, or if "<key>PayloadDisplayName</key> <string>Passcode</string>" does not appear in the configuration profile, or the password policy from the iOS Over-the-Air management tool is not present on the iOS device, this is a finding.

Fix Text

Configure Apple iOS to require a valid password be successfully entered before the mobile device data is unencrypted. In the iOS Over-the-Air management tool, configure a passcode profile. Note: Any content in the profile will trigger the requirement for a passcode on the iOS device. For example, in Mobile Iron Admin Portal, edit the policy and select the "Mandatory" radio button for "Password".
