<GroupDescription></GroupDescription>
The EMM system supporting the iOS/iPadOS 16 BYOAD must be configured to detect if the BYOAD native security controls are disabled.
Medium Severity
<VulnDiscussion>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.

<GroupDescription></GroupDescription>
The BYOAD and DOD enterprise must be configured to limit access to only enterprise corporate-owned IT resources approved by the authorizing official (AO).
High Severity
<VulnDiscussion>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 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.
