Description
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. 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. SFR ID: FMT_SMF.1.1 #8

Who does this work

7 NICE work roles and 5 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-278755r1151153_chk)

Review configuration settings to confirm that Siri is disabled on the Lock screen. 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 Siri while device is locked" is unchecked. Alternatively, verify the text "<key>allowAssistantWhileLocked</key><false/>" appears in the configuration profile (.mobileconfig file). 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 Apple iOS/iPadOS management tool containing the restrictions policy. 5. Tap "Restrictions". 6. Verify "Siri while locked not allowed" is listed. If "Allow Siri while device is locked" is checked in the Apple iOS/iPadOS management tool, or "<key>allowAssistantWhileLocked</key><true/>" appears in the configuration profile, or the restrictions policy on the iPhone and iPad from the Apple iOS/iPadOS management tool does not list "Siri while locked not allowed", this is a finding. Note: If Siri use has been disabled, "Siri while locked not allowed" may not be listed and this requirement is Not Applicable.

Fix Text (F-83194r1150511_fix)

Install a configuration profile to disable Siri while the device is locked. Configuration Profile Key: allowAssistantWhileLocked
