The device lock function prevents further access to the system by initiating a session lock after a period of inactivity or upon receiving a request from a user. The device lock is retained until the user reestablishes access using established identification and authentication procedures. A device lock is a temporary action taken when a user stops work but does not want to log out because of the temporary nature of the hiatus. During the device lock a publicly viewable pattern is visible on the associated display, hiding what was previously visible on the screen. Once invoked, the device lock shall remain in place until the user re-authenticates. No other system activity aside from re-authentication can unlock the system. The operating system must enforce a device lock function. This prevents others from gaining access to the device when not in the user's possession and accessing sensitive DoD information. The identification and authentication procedure configuration must be set by a Mobile Device Management (MDM) service and be sufficiently complex to protect sensitive data.

The device lock function prevents further access to the system by initiating a session lock after a period of inactivity or upon receiving a request from a user. The device lock is retained until the user reestablishes access using established identification and authentication procedures. A device lock is a temporary action taken when a user stops work but does not want to shut down because of the temporary nature of the hiatus. During the device lock a publicly viewable pattern is visible on the associated display, hiding what was previously visible on the screen. Once invoked, the device lock shall remain in place until the user re-authenticates. No other system activity aside from re-authentication can unlock the system. The operating system must lock the device after the organization defined time period. This prevents others from gaining access to the device when not in the user's possession and accessing sensitive DoD information. A device lock mitigates the risk that an adversary can access data on an unattended mobile device but only after the maximum of 15 minute period of inactivity.

Determining the correct time a particular application event occurred on a system is critical when conducting forensic analysis and investigating system events. Periodically synchronizing internal clocks with an authoritative time source is needed in order to correctly correlate the timing of events that occur across the enterprise. The two authoritative time sources for mobile operating systems are an authoritative time server which is synchronized with redundant United States Naval Observatory (USNO) time servers as designated for the appropriate DoD network (NIPRNet or SIPRNet) or the Global Positioning System (GPS). Timestamps generated by the audit system in mobile operating systems shall include both date and time. The time may be expressed in Coordinated Universal Time (UTC), a modern continuation of Greenwich Mean Time (GMT), or local time with an offset from UTC.

Password complexity or strength refers to how difficult it is to determine a password using a dictionary or brute force attack. Setting minimum numbers of certain types of characters increases password complexity, and therefore makes it more difficult for an adversary to discover the password. In the DoD, the expectation is that the setting will range from a minimum of 1 to 2 upper case alphabetic characters in the device unlock password. The parameter should be selected based on a risk assessment that weighs factors, such as the environments the device will be located and operational requirements for users to access data in a timely manner.

Permitting mobile service carriers access to the mobile operating system leaves the device vulnerable to breach from rogue elements within the carrier infrastructure. Mobile service carriers are not subject to the same personnel, operational, and technical controls as DoD organizations. For example, its employees in most cases do not have active DoD clearances. When a mobile service carrier must update software or configuration on a mobile device, these updates must come from a DoD approved source, which in many cases is the vendor of the MOS software. Preventing mobile service carrier access to mobile operating systems greatly mitigates the risk associated with this vulnerability. Research In Motion does not pre-install any software that would allow carriers to access or manipulate a BlackBerry device. As well, all applications available through App World are tested and monitored for malicious code, and applications must be signed by RIM to allow them to be installed on a BlackBerry Device, and these applications and their permissions must be acknowledged by the user or system administrator before they can be installed.
Checks: C-46283r1_chk

DoD can perform due diligence on sources of software to mitigate the risk that malicious software is introduced to those sources. Therefore, if software is downloaded from a DoD approved source, then it is less likely to be malicious than if it is downloaded from an unapproved source. To prevent access to unapproved sources, the operating system in most cases can be configured to disable user access to public application stores. However, in some cases, DoD may approve downloads directly from the OS vendor.

Proxy servers can inspect traffic for malware and other signs of a security attack. Allowing a mobile device to access the public Internet without proxy server inspection forgoes the protection that the proxy server would otherwise provide. Malware downloaded onto the device could have a wide variety of malicious consequences, including loss of sensitive DoD information. Forcing traffic to flow through a proxy server greatly mitigates the risk of access to public Internet resources.

Security related parameters are those parameters impacting the security state of the system and include parameters related to the implementation of other IA controls. If these controls are not implemented, the system may be vulnerable to a variety of attacks. The use of an MDM allows an organization to assign values to security related parameters across all the devices it manages. This provides assurance that the required mobile OS security controls are being enforced, and that the device user or an adversary has not modified or disabled the controls. It also greatly increases efficiency and manageability of devices in a large scale environment relative to an environment in which each device must be configured separately.

If data at rest is unencrypted, it is vulnerable to disclosure. Even if the operating system enforces permissions on data access, an adversary can remove non-volatile memory and read it directly, thereby circumventing operating system controls. Encrypting the data ensures that confidentiality is protected even when the operating system is not running. AES encryption with appropriate key lengths provides assurance that the cryptography is adequate.

The device acts as a personal hotspot when it accepts remote connections on a local area network interface for the purposes of routing traffic to a wide area network interface. The most common implementation is to accept local area Wi-Fi connections to reach ISP service provided by a cellular data carrier. The objective is to ensure the remote devices are not able to access any applications, data, or other operating system functionality on the device. A core assumption of the MOS SRG is that mobile devices do not serve applications to remote devices. If remote access to applications and data were feasible, this would open up a wide variety of vulnerabilities in which an adversary with a remote wireless capability could breach system security. Precluding this possibility greatly mitigates the risk of such an attack.

If the user is able to disable the password-protected lock feature, the user can change the configuration of the device to allow access without a password. The modified configuration would enable an adversary with access to the device to obtain DoD information and possibly other information resources on other systems. An operating system that does not allow a user to disable this feature mitigates the risk of this attack. In cases in which the mobile operating system relies on another application for protected data storage (e.g., if FIPS 140-2 validated encryption for unclassified use is not native to the device), then this requirement applies to both the device lock password and the password to the data storage application.
