Vuln Rule Version CCI Severity Title Description
SV-60041r3_rule BB10-2X-000100 CCI-000048 MEDIUM BlackBerry 10 OS must display the DoD warning banner exactly as specified at start-up device unlock. The operating system is required to display the DoD-approved system use notification message or banner before granting access to the system that provides privacy and security notices consistent with applicable federal laws, Executive Orders, directives, policies, regulations, standards, and guidance. This ensures the legal requirements for auditing and monitoring are met. System use notification messages must be displayed when individuals log in to the information system. The approved DoD text must be used as specified in the DoD Instruction 8500.01 dated March 14, 2014.
SV-60043r2_rule BB10-2X-000110 CCI-000056 MEDIUM BlackBerry 10 OS must retain the lock on the Work Space until the user reestablishes access using established identification and authentication procedures. 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.
SV-60045r2_rule BB10-2X-000120 CCI-000056 MEDIUM BlackBerry 10 OS must retain the device lock until the user reestablishes access using established identification and authentication procedures. 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.

SV-60047r3_rule BB10-2X-000130 CCI-000057 MEDIUM BlackBerry 10 OS must lock the Work Space after no more than 15 minutes of inactivity. 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.
SV-60049r3_rule BB10-2X-000140 CCI-000057 MEDIUM BlackBerry 10 OS must prevent applications from extending the Work Space password lock time. The Work Space lock function prevents further access to the Work Space by initiating a session lock after a period of inactivity on the device or upon receiving a request from a user. The lock is retained until the user reestablishes access using established identification and authentication procedures. When using a personal app designed to extend the timeout in configurations with both personal and work areas, the device will not lock but the Work Space will lock after 15 minutes. Locking the Work Space after 15 minutes ensures that an adversary acquiring a DoD device may have access to the personal space but only a limited window to gain information from the Work Space. 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.
SV-60051r2_rule BB10-2X-000150 CCI-000160 LOW BlackBerry 10 OS must synchronize the internal clock on an organizationally-defined periodic basis with an authoritative time server or the Global Positioning System. 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.
SV-60053r3_rule BB10-2X-000210 CCI-000205 MEDIUM BlackBerry 10 OS must enforce a minimum length for the Work Space unlock password. Password complexity, or strength, is a measure of the effectiveness of a password in resisting guessing and brute force attacks. The ability to crack a password is a function of how many times an attempt to crack the password, how quickly the adversary can do each attempt, and the size of the password space. The longer the minimum length of the password is, the larger the password space.
SV-60055r5_rule BB10-2X-000220 CCI-000663 MEDIUM BlackBerry 10 OS must prevent a user from installing unapproved applications. The operating system must enforce software installation by users based upon what types of software installations are permitted (e.g., updates and security patches to existing software) and what types of installations are prohibited (e.g., software whose pedigree with regard to being potentially malicious is unknown or suspect) by the organization. The installation and execution of unauthorized software on an operating system may allow the application to obtain sensitive information or further compromise the system. Preventing a user from installing unapproved applications mitigates this risk. When the Development Mode is enabled on BlackBerry 10 OS devices, the user has the capability to sideload apps to either the Work Space or Personal Space. Disabling this feature removes the capability for a user to sideload apps.
SV-60057r3_rule BB10-2X-000224 CCI-000663 HIGH BlackBerry 10 OS must prevent a user from installing unapproved applications in the Work Space. The operating system must enforce software installation by users based upon what types of software installations are permitted (e.g., updates and security patches to existing software) and what types of installations are prohibited (e.g., software whose pedigree with regard to being potentially malicious is unknown or suspect) by the organization. The installation and execution of unauthorized software on an operating system may allow the application to obtain sensitive information or further compromise the system. Preventing a user from installing unapproved applications mitigates this risk. When the Development Mode is enabled for the Work Space on BlackBerry 10 OS devices, the user has the capability to sideload apps to the Work Space. Disabling this feature removes the capability for a user to sideload apps.
SV-60059r4_rule BB10-2X-000228 CCI-000663 MEDIUM BlackBerry 10 OS must prevent a user from installing unapproved applications from other sources. The operating system must enforce software installation by users based upon what types of software installations are permitted (e.g., updates and security patches to existing software) and what types of installations are prohibited (e.g., software whose pedigree with regard to being potentially malicious is unknown or suspect) by the organization. The installation and execution of unauthorized software on an operating system may allow the application to obtain sensitive information or further compromise the system. Preventing a user from installing unapproved applications mitigates this risk.
SV-60061r3_rule BB10-2X-000230 CCI-000663 MEDIUM BlackBerry 10 OS must only permit downloading of software from a DoD-approved source (e.g., DoD-operated mobile device application store or MDM server). 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.
SV-60063r2_rule BB10-2X-000240 CCI-000780 MEDIUM BlackBerry 10 OSs Wi-Fi module must use EAP-TLS authentication when authenticating to DoD WLAN authentication servers. Without strong mutual authentication a mobile device may connect to an unauthorized network. In many cases, the user may falsely believe that the device is connected to an authorized network and then provide authentication credentials and other sensitive information. EAP-TLS is strong mutual authentication leveraging a public key infrastructure. Its use greatly mitigates risk associated with authentication transactions.
SV-60065r3_rule BB10-2X-000250 CCI-000780 MEDIUM BlackBerry 10 OS VPN client must employ DoD PKI-approved mechanisms for authentication when connecting to DoD networks. VPNs are vulnerable to attack if they are not supported by strong authentication. An adversary may be able to gain access to network resources and sensitive information if they can compromise the authentication process. Common Access Card (CAC) authentication is a strong cryptographic two-factor authentication that greatly mitigates the risk of VPN authentication breaches. Other DoD-approved PKI mechanisms provide similar levels of assurance. Reference the DoD CIO memorandum regarding interim guidance on the use of derived PKI credentials (2015-05-06 DoD Interim Guidance for Implementing Derived PKI Credentials on Unclass CMDs) for BlackBerry certificate configuration information.
SV-60069r4_rule BB10-2X-000280 CCI-000366 MEDIUM BlackBerry 10 OS must have access to DoD root and intermediate PKI certificates when performing DoD PKI-related transactions. DoD root and intermediate PKI certificates are used to verify the authenticity of PKI certificates of users and web services. If the root and intermediate certificates are not available, an adversary could falsely sign a certificate in such a way that it could not be detected. Providing access to the DoD root and intermediate PKI certificates greatly diminishes the risk of this attack.
SV-60071r4_rule BB10-2X-000290 CCI-001154 MEDIUM BlackBerry 10 OS must block both the inbound and outbound traffic between instant messaging clients that are independently configured by end users and external service providers or other unapproved DoD systems. Many instant messaging systems have known vulnerabilities, some of which allow an adversary to install malware on the device. This malware can then be used to obtain sensitive information or further compromise DoD information systems. Restricting IM traffic to DoD-authorized IM systems mitigates the risk of using IM technology.
SV-60073r3_rule BB10-2X-000300 CCI-000366 HIGH BlackBerry 10 OS must grant a downloaded application only the permissions the AO has authorized for that application. Mobile operating system applications that are able to perform unintended functions may be able to obtain sensitive information or otherwise compromise system security. The permissions that an application requires to perform its function may be delineated in a permissions manifest or in entitlements that are either bound to the application or embedded in its code. Enforcing these permissions limitations is necessary to ensure the application is not permitted to perform unintended functions.
SV-60075r3_rule BB10-2X-000310 CCI-001159 HIGH The BlackBerry 10 OS Work Space must only install and use DoD PKI-issued or DoD-approved software authentication certificates. If unauthorized software authentication certificates are installed on the device, then the operating system would not block malware signed by the entity that published these certificates. Such malware could be used to obtain sensitive DoD information or to further breach system security. Eliminating unapproved software authentication certificates greatly mitigates the risk of malware passing authentication controls.
SV-60077r3_rule BB10-2X-000320 CCI-001159 MEDIUM The BlackBerry 10 OS Work Space must only install and use DoD PKI-issued or DoD-approved server authentication certificates. If unauthorized device authentication certificates are installed on the device, there is the potential that the device may connect to a rogue device or network. Rogue devices can mimic the behavior of authorized equipment to trick the user into providing authentication credentials, which could then in turn be used to compromise DoD information and networks. Restricting device authentication certificates to an authorized list mitigates the risk of attaching to rogue devices and networks.
SV-60079r2_rule BB10-2X-000325 CCI-001237 MEDIUM BlackBerry 10 OS must be updated to the latest approved version of the operating system. Operating system updates contain new security related features and security patches that address known vulnerabilities. Running the latest DoD-approved software version improves the security posture of the mobile device.
SV-60087r2_rule BB10-2X-000350 CCI-000366 MEDIUM BlackBerry 10 OS maximum number of consecutive unsuccessful unlock attempts must be less than 10. The recommended setting for the maximum number of consecutive unsuccessful unlock attempts is 10. In some environments, a lower number may be needed to provide greater protection of sensitive information. Allowing for configuration enables the local command to enforce greater protection when it is deemed necessary. If the limit is not configurable, then it is permissible for a site to procure and deploy devices that enforce the limit specified by the organization, so long as that limit does not exceed 10.
SV-60089r2_rule BB10-2X-000360 CCI-000370 MEDIUM BlackBerry 10 OS must employ mobile device management services to centrally manage IT Policies. 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 mobile device management (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.
SV-60091r2_rule BB10-2X-000370 CCI-000370 MEDIUM BlackBerry 10 OS must employ mobile device management services to centrally manage email settings. 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 mobile device management (MDM) allows an organization to assign values to security related parameters across all the devices it manages.

SV-60093r2_rule BB10-2X-000380 CCI-000370 MEDIUM BlackBerry 10 OS must employ mobile device management services to centrally manage Wi-Fi profiles. 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 mobile device management (MDM) allows an organization to assign values to security related parameters across all the devices it manages.

SV-60095r2_rule BB10-2X-000390 CCI-000370 MEDIUM BlackBerry 10 OS must employ mobile device management services to centrally manage VPN profiles. 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.

SV-60101r2_rule BB10-2X-000430 CCI-000366 LOW BlackBerry 10 OS must enable a system administrator to (i) select which data fields will be available to applications outside of the contact database application and (ii) limit the number of contact database fields accessible outside of a work persona in the case of dual persona phones. The contact database often contains a significant amount of information beyond each person's name and phone number. The records may contain addresses and other identifying or sensitive information that should not be revealed. There may be cases in which an organization has determined it is an acceptable risk to distribute parts of a person's contact record but not others. Enabling the system administrator to select which fields are available outside the contact database application (or to applications outside the work persona in the case of a dual persona device) assists with management of the risk.
SV-60103r1_rule BB10-2X-002140 CCI-000060 MEDIUM BlackBerry 10 OS device lock, when activated on a device, must place a publicly viewable pattern onto the associated display, hiding what was previously visible on the screen. 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 lock the device with a publicly viewable pattern visible on the associated display, hiding what was previously visible on the screen. This prevents others from gaining access to the device when not in the user's possession and accessing sensitive DoD information. Publicly viewable patterns can include screen saver patterns, photographic images, solid colors, or a blank screen, so long as none of those patterns convey sensitive information. Non-sensitive device information, such as battery life, signal strength, and time/date, may be viewable as part of a publically viewable pattern. However, system notifications, user or contact information must not be viewable because they may reveal owner or organizational information.
SV-60105r2_rule BB10-2X-002160 CCI-000185 LOW BlackBerry 10 OS, for PKI-based authentication must validate certificates by querying the certification authority for revocation status of the certificate. Status information for certification paths includes certificate revocation lists or online certificate status protocol responses. Failure to verify a certificate's revocation status can result in the system accepting a revoked or otherwise unauthorized certificate resulting in installation of unauthorized software or connection to rogue networks. Querying for certificate revocation mitigates the risk that the system will accept an unauthorized certificate.
SV-61473r2_rule BB10-2X-000270 CCI-001130 MEDIUM BlackBerry 10 OSs VPN client must use either IPsec or SSL/TLS when connecting to DoD networks. Use of non-standard communications protocols can affect both the availability and confidentiality of communications. IPsec and SSL/TLS are both well-known and tested protocols that provide strong assurance with respect to both IA and interoperability.
