Description
Multi-user mode allows multiple users to share a mobile device by providing a degree of separation between user data. To date, no mobile device with multi-user mode features meets DoD requirements for access control, data separation, and non-repudiation for user accounts. In addition, the MDFPP does not include design requirements for multi-user account services. Disabling multi-user mode mitigates the risk of not meeting DoD multi-user account security policies.
