Commercial Mobile Device (CMD) Policy Security Technical Implementation Guide (STIG)

Mobile devices with cameras are easily used to photograph sensitive information and areas if not addressed. Sites must establish, document, and train on how to mitigate this threat. Information Assurance OfficerSecurity ManagerECWN-1

If appropriate procedures are not followed prior to disposal of a CMD, an adversary may be able to obtain sensitive DoD information or learn aspects of the configuration of the device that might facilitate a subsequent attack.System AdministratorInformation Assurance OfficerECSC-1, PECS-1

Users are the first line of security controls for CMD systems. They must be trained in using CMD security controls or the system could be vulnerable to attack.System AdministratorInformation Assurance OfficerPETN-1

Sensitive DoD data could be stored in memory on a DoD operated mobile operating system (OS) based CMD and the data could be compromised if required actions are not followed when a CMD is lost or stolen. Without procedures for lost or stolen mobile operating system (OS) based CMD devices, it is more likely that an adversary could obtain the device and use it to access DoD networks or otherwise compromise DoD IA.Information Assurance OfficerECSC-1, VIIR-1, VIIR-2

Malware can be installed on the device at some point between shipping from the factory and delivery to DoD. The malware could result in the compromise of sensitive DoD information or result in the introduction of malware within the DoD network.System AdministratorInformation Assurance OfficerECWN-1

Users must not accept Over-The-Air (OTA) wireless software updates from the wireless carrier or other non-DoD sources unless the updates have been tested and approved by the IAO. Unauthorized/unapproved software updates could include malware or cause a degradation of the security posture of the CMD and DoD network infrastructure. All software updates should be reviewed and/or tested by the smartphone system administrator and originate from a DoD source or DoD-approved source. Wireless software updates should be pushed from the CMD management server, when this feature is available.System AdministratorECWN-1

If the policy does not include information on Wi-Fi security controls, then it is more likely that the security controls will not be implemented properly. Wi-Fi is vulnerable to a number of security breaches without appropriate controls. These breaches could involve the interception of sensitive DoD information and the use of the device to connect to DoD networks. System AdministratorInformation Assurance OfficerECWN-1

S/MIME provides the user with the ability to digitally sign and encrypt email messages, to verify the digital signatures on received messages, and to decrypt messages received from others if those messages are encrypted. Digital signatures provide strong cryptographic assurance of the authenticity and integrity of the signed message, including attachments. This capability protects against the insertion of malicious mobile code and social engineering attacks in which an adversary masquerades as a known user, as well as other exploits. Encryption provides confidentiality for sensitive information, which is particularly valuable when messages are sent to or received from users external to DoD messaging infrastructure, as such messages would otherwise travel in the clear over the public Internet. The use of software certificates adds additional risk of compromise to the user's digital certificates and to the DoD PKI infrastructure. DoD PKI certificates may not be provisioned in the native mobile operating system certificate store unless the certificate is protected with a valid FIPS 140-2 validated cryptographic module.

If procedures for lost or stolen CMDs are not followed, it is more likely that an adversary could obtain the device and use it to access DoD networks or otherwise compromise DoD IA.System AdministratorInformation Assurance OfficerECSC-1

Improper use of wireless remote access to a DoD network can compromise both the wireless client and the network, as well as, expose DoD data to unauthorized people. Without adequate training remote access users are more likely to engage in behaviors that make DoD networks and information more vulnerable to security exploits.System AdministratorInformation Assurance OfficerPRTN-1

Wireless clients, DoD data, and the DoD network could be compromised if operational policies for the use of wireless remote access are not documented by the site.System AdministratorInformation Assurance OfficerECWN-1

Wireless client, networks, and data could be compromised if unapproved wireless remote access is used. In most cases, unapproved devices are not managed and configured as required by the appropriate STIG and the site’s overall network security controls are not configured to provide adequate security for unapproved devices. When listed in the SSP, the site has shown that security controls have been designed to account for the wireless devices.Information Assurance OfficerDesignated Approving AuthorityECWN-1

Users are the first line of security controls for CMD systems. They must be trained in using CMD security controls or the system could be vulnerable to attack. If training is not renewed on an annual basis, users may not be informed of new security procedures or may forget previously trained procedures, which could lead to an exposure of sensitive DoD information.Information Assurance OfficerPETN-1
