GOOG-13-800500: The EMM system supporting the Google Android 13 BYOAD must be configured to detect if known malicious applications, blocked, or prohibited applications are installed on the Google Android 13 BYOAD (DOD-managed segment only).
Verify an app vetting process is being used to vet apps before work profile apps are placed in the MDM app repository. If an app vetting process is not being used to vet apps before work profile apps are placed in the MDM app repository, this is a finding.
Discussion
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 collecting and analysis of BYOAD generated logs for noncompliance indicators is acceptable. This detection capability must be implemented prior to AMD (Approved Mobile Device, called BYOAD device in the STIG) enrollment, AMD access to DOD information and IT resources, and continuously monitored on the DOD-managed segment of the AMD enrolled in the program. If non-DOD information (i.e., personal user data, device information) outside the DOD-managed segment of the AMD 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. Reference: DOD policy "Use of Non-Government Mobile Devices" (3.a.(3)iii). SFR ID: FMT_SMF_EXT.1.1 #47
Fix
Implement an app vetting process before work profile apps are placed in the MDM app repository.

GOOG-13-802300: The Google Android 13 BYOAD must be configured to disable device cameras and/or microphones when brought into DOD facilities where mobile phone cameras and/or microphones are prohibited.
Verify Google Android 13 BYOADs are prohibited in DOD facilities that prohibit mobile devices with cameras and microphones. If for DOD sites that prohibit mobile devices with cameras and microphones, Google Android 13 BYOADs have not been prohibited from the facility by the ISSO/ISSM, this is a finding.
Discussion
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 ISSO/ISSM. If BYOAD devices are brought into facilities where the AO has determined the risk of using mobile device cameras or microphones is unacceptable, this could lead to the exposure of sensitive DOD data. SFR ID: FMT_SMF_EXT.1.1 #47
Fix
Do not allow Google Android 13 BYOADs in DOD facilities where mobile phone cameras and/or microphones are prohibited.

GOOG-13-801100: The Google Android 13 BYOAD and DOD enterprise must be configured to limit access to only AO-approved, corporate-owned enterprise IT resources.
Verify the EMM system and DOD enterprise have been configured to limit the Google Android 13 BYOAD access to only AO-approved enterprise IT resources. The exact procedure will depend on the EMM system used and IT resources at the site. If the EMM system and DOD enterprise have not been configured to limit Google Android 13 BYOAD access to only AO-approved enterprise IT resources, this is a finding.
Discussion
Note: IT resources includes DOD networks and applications (for example, DOD email). The System Administrator must have the capability to limit access of the BYOAD to DOD networks and DOD IT resources based on mission needs and risk. An adversary could exploit vulnerabilities created by the weaker configuration to compromise DOD sensitive information. The AO should document networks, IT resources, and enterprise applications that BYOAD can access. Examples of EMM security controls are as follows: 1. Device access restrictions: Restrict or isolate access based on the devices 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.b.(2)ii). SFR ID: FMT_SMF_EXT.1.1 #47
Fix
