DOD policy requires BYOAD devices with DOD data be managed by a DOD MDM server, MAM server, or VMI system. This ensures the device can be monitored for compliance with the approved security baseline and managed data and apps can be removed when the device is out of compliance, which protects DOD data from unauthorized exposure. Examples of possible EMM security controls are as follows: 1. Device access restrictions: Restrict or isolate access based on the device's access type (i.e., from the internet), authentication type (e.g., password), credential strength, etc. 2. User and device activity monitoring: Configured to detect anomalous activity, malicious activity, and unauthorized attempts to access DOD information. 3. Device health tracking: Monitor device attestation, health, and agents reporting compromised applications, connections, intrusions, and/or signatures. Reference: DOD policy "Use of Non-Government Mobile Devices". 3.a.(3)ii, 3.b.(2)ii,1 and 2. SFR ID: FMT_SMF_EXT.1.1 #47

Verify the EMM system supporting the iOS/iPadOS 17 BYOAD has been configured to conduct autonomous monitoring, compliance, and validation to ensure security/configuration settings of mobile devices do not deviate from the approved configuration baseline. The exact procedure will depend on the EMM system used at the site. If the EMM system supporting the iOS/iPadOS 17 BYOAD has not been configured to conduct autonomous monitoring, compliance, and validation to ensure security/configuration settings of mobile devices, this is a finding.

Examples of indicators that the device native security controls have been disabled include jailbroken or rooted devices. DOD policy requires BYOAD devices with DOD data be managed by a DOD MDM server, MAM server, or VMI system. This ensures the device can be monitored for compliance with the approved security baseline and the work profile can be removed when the device is out of compliance, which protects DOD data from unauthorized exposure. Detection via collection and analysis of BYOAD-generated logs for noncompliance indicators is acceptable. This detection capability must be implemented prior to BYOAD access to DOD information and IT resources and continuously monitored on the DOD-managed segment of the BYOAD enrolled in the program. If non-DOD information (i.e., personal user data, device information) outside the DOD-managed segment of the BYOAD is required to be accessed, collected, monitored, tracked (i.e., location), or maintained, the circumstances under which this may be done must be outlined in the user agreement.

Review configuration settings to confirm "Allow Trusting New Enterprise App Authors" is disabled. 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 "Allow Trusting New Enterprise App Authors" is disabled. 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 restrictions policy. 5. Tap "Restrictions". 6. Verify "Trusting enterprise apps not allowed" is listed. If "Allow Trusting New Enterprise App Authors" is not disabled in the iOS/iPadOS management tool or on the iPhone and iPad, this is a finding. Note: This requirement is the same as AIOS-17-707000 in the Apple iOS/iPadOS 17 BYOAD STIG.

DOD policy states BYOAD owners must sign a user agreement and be made aware of what personal data and activities will be monitored by the enterprise by including this information in the user agreement. Reference: DOD policy "Use of Non-Government Mobile Devices" 3.a.(3)ii, and 3.c.(4). SFR ID: FMT_SMF_EXT.1.1 #47

Verify the user agreement includes a description of what personal data and information is being monitored, collected, or managed by the EMM system or deployed agents or tools. If the user agreement does not include a description of what personal data and information is being monitored, collected, or managed by the EMM system or deployed agents or tools, this is a finding.

DOD policy requires BYOAD devices with DOD data be managed by a DOD MDM server, MAM server, or VMI system. This ensures the device can be monitored for compliance with the approved security baseline and managed data and apps can be removed when the device is out of compliance, which protects DOD data from unauthorized exposure. Follow local physical security procedures regarding allowing or prohibiting personally owned mobile devices in a DOD facility. If BYOAD devices are brought into facilities where the authorizing official (AO) has determined the risk of using personal devices is unacceptable, this could lead to the exposure of sensitive DOD data.

Verify the DOD Mobile Service Provider or information system security officer (ISSO)/information system security manager (ISSM) do not allow BYOADs in facilities where personally owned mobile devices are prohibited. If the DOD Mobile Service Provider or ISSO/ISSM allows BYOADs in facilities where personally owned mobile devices are prohibited, this is a finding.

In some DOD operational environments, the use of the mobile device camera or microphone could lead to a security incident or compromise of DOD information. The system administrator must have the capability to disable the mobile device camera and/or microphone based on mission needs. Alternatively, mobile devices with cameras or microphones that cannot be disabled must be prohibited from the facility by the information system security officer (ISSO)/information system security manager (ISSM). If BYOAD devices are brought into facilities where the authorizing official (AO) has determined the risk of using mobile device cameras or microphones is unacceptable, this could lead to the exposure of sensitive DOD data.

Determine if iOS/iPadOS 17 BYOADs are prohibited in DOD facilities that prohibit mobile devices with cameras and microphones. Refer to the site Facility Security Standard Operating Procedure (SOP) to determine site requirements. If for DOD sites that prohibit mobile devices with cameras and microphones, the ISSO/ISSM has not prohibited iOS/iPadOS 17 BYOADs from the facility, this is a finding.

Fix: F-63401r943598_fix

Do not allow iOS iPadOS 17 BYOADs in DOD facilities where mobile phone cameras and/or microphones are prohibited. Refer to the site Facility Security SOP to determine site requirements.

c
The mobile device used for BYOAD must be NIAP validated.

Note: For a virtual mobile infrastructure (VMI) solution, both the client and server components must be NIAP compliant. Nonapproved mobile devices may not include sufficient controls to protect work data, applications, and networks from malware or adversary attack. Components must only approve devices listed on the NIAP product compliant list or products listed in evaluation at the following links respectively: - https://www.niap-ccevs.org/Product/ - https://www.niap-ccevs.org/Product/PINE.cfm Reference: DOD policy "Use of Non-Government Mobile Devices". 3.b.(1)i.

Verify the mobile device used for BYOAD is NIAP validated (included on the NIAP list of compliant products or products in evaluation). If the mobile device used for BYOAD is not NIAP validated (included on the NIAP list of compliant products or products in evaluation), this is a finding.

Fix: F-63402r943601_fix

Use only mobile devices for BYOAD that are NIAP validated (included on the NIAP list of compliant products or products in evaluation).
