Description
Sensitive DoD data could be compromised if a device unlock password/passcode is not set to the required complexity on DoD CMDs. The DoD CMD password requirements for protecting sensitive data are that the password must be at least 8 characters in length and contain at least one lowercase letter, one uppercase letter, and one number. In addition, sequential characters/numbers may not be used in the password. It is not currently possible to require both an uppercase letter and lowercase letter for the iOS passcode, or to enforce the sequential character restriction, so the iOS passcode must contain a special character to approximate the same password strength as the DoD-specified password complexity rules.

1. Make a list of all iOS security policies listed on the MDM server that have been assigned to iOS devices and review each policy. 2. Select each security policy iOS devices are assigned to and, in turn, verify the required settings are in the policy. Verify "Minimum number of complex characters” is checked and at least “1 character” is selected in the iOS security policy. Mark as a finding if the required rule is not set up on the MDM server. Note: If there is a finding, note the name of the policy in the Findings Details section in VMS/Component Provided Tracking Database.
