Detailed Policy Requirements: This requirement applies to mobile operating system (OS) CMDs. This mobile devices. This requirement also applies to sensitive DoD information stored on mobile OS devices that are not authorized to connect to DoD networks or store/process sensitive DoD information. Sensitive DoD data or information is defined as any data/information that has not been approved for public release by the site/Command Public Affairs Officer (PAO). In accordance with DoD policy, all components must establish Incident Handling and Response procedures. A CMI or “data spill” occurs when a classified email is inadvertently sent on an unclassified network and received on a wireless email device. Classified information may also be transmitted through some other form of file transfer to include web browser downloads and files transferred through tethered connections. CMDs Mobile devices are not authorized for processing classified data. A data spill also occurs if a classified document is attached to an otherwise unclassified email. A For BlackBerry and Good Mobile Messaging systems, a data spill will only occur if the classified attached document is viewed or opened by the CMD mobile device user since the CMD mobile device system only downloads an attachment on the CMD mobile device if the user views or opens the attachment. The site's Incident Handling and Response procedures should reference NSA/CSS Storage Device Declassification Manual 9-12, Section 5, for smartphone destruction procedures. Check Procedures: Interview the ISSO. Verify classified incident handling, response, and reporting procedures are documented in site CMD mobile device procedures or security policies. If classified incident handling, response, and reporting procedures are not documented in site CMD mobile device procedures or security policies, this is a finding. This requirement applies at both sites where CMDs mobile devices are issued and managed and at sites where the CMD mobile device management server is located. - At the CMD mobile device management server site, verify Incident Handling and Response procedures include actions to sanitize the CMD mobile device management server and email servers (e.g., Exchange, Oracle mail). - At CMD mobile device sites, verify Incident Handling and Response procedures include actions for incident reporting and actions to safeguard classified smartphone devices. The following actions will be followed for all CMDs mobile devices involved in a data spill: If Incident Handling and Response procedures do not include required information, this is a finding.

Discussion

When a data spill occurs on a CMD, mobile device, classified or sensitive data must be protected to prevent disclosure. After a data spill, the CMD mobile device must either be wiped using approved procedures, or destroyed if no procedures are available, so classified or sensitive data is not exposed. If a data spill procedure is not published, the site may not use approved procedures to remediate after a data spill occurs and classified data could be exposed.

Fix

Publish a Classified Message Incident (CMI) procedure or policy for the site.
