Detailed Policy Requirements: For CMDs deployed under an Interim Security Configuration Guide (ISCG) or the DoD CIO’s 6 April 2011 memorandum, Use of Commercial Mobile Devices (CMD) in the Department of Defense (DoD), the approval authority is the Component CIO. The site must have an Interim Authority To Test (IATT) issued by the Component CIO. For all other wireless devices and systems the Designated Approval Authority (DAA) must approve the wireless device or system. Detailed Check Procedures: Work with the site POC to verify documentation. Performed with WIR0016 (equipment list). For CMD systems without a STIG, verify the site has an approved IATT. Mark as a finding if a valid IATT is not available or is not signed by the Component CIO. For all other wireless devices or systems, complete the following: 1. Request copies of written DAA approval documentation. Any of the following documents meets this requirement as proof of compliance: - The DIACAP IA Implementation Plan must show the wireless system as part of the network diagram or list the system/equipment as being part of the network. - DAA approval letter or other document. The document must list the system or equipment and date its use is approved. The DAA approval letter or SSP may be a general statement of approval rather than list each device. 2. Verify DAA approval for type of device used, such as wireless connection services, peripherals, and applications. Mark as a finding for any of the following reasons: - Wireless systems, devices, services, or accessories are in use but DAA approval letter(s) do not exist. - If, in the judgment of the reviewer, configuration differs significantly from that approved by the DAA approval letter. Note: The DAA approval for the wireless system does not need to be documented separately from other DAA approval documents for the site network, as long as the approval documents list the wireless system. For example, if a site network ATO lists the wireless system, the ATO meets the requirements of this check. For Secure Mobile Environment Portable Electronic Device (SME PED), the following applies: - An ATO or an IATO has been signed by the DAA prior to the connection of the unclassified Sensa server to the NIPRNet. - Classified Connection Approval Office (CCAO) approval has been obtained prior to the connection of the classified Sensa server to the SIPRNet. Note: The intent of this check is to ensure the DAA has approved the use of the wireless system being reviewed at the site. This approval can be documented in several ways. The most common is the SSP for the site includes the wireless system and the DAA has signed the SSP. If the command uses an enterprise wide SSP including the wireless system being reviewed and the SSP applies to site being reviewed, then the requirement has been met.
Obtain DAA approval (documented by memo or SSP) prior to wireless systems being installed and used. For CMD systems without a STIG, obtain an IATT prior to wireless systems being installed and used.
Detailed Policy Requirements: This check applies to any wireless end user device (smartphone, tablet, Wi-Fi network interface card, etc.) and wireless network devices (access point, authentication server, etc.). The list of approved wireless devices will be stored in a secure location and will include the following at a minimum: - Access point Media Access Control (MAC) address (WLAN only), - Access point IP address (WLAN only), - Wireless client MAC address, - Network DHCP range (WLAN & WWAN only), - Type of encryption enabled, - Access point SSID (WLAN only), - Manufacturer, model number, and serial number of wireless equipment, - Equipment location, and - Assigned users with telephone numbers. For CMDs: - Manufacturer, model number, and serial number of wireless equipment. - Equipment location or who the device was issued to. - Assigned users with telephone numbers and email addresses. For SME PED: Local commands will keep track of devices by assigning a control number or using the serial number for accountability purposes. Check Procedures: Work with the site POC: 1. Request copies of site’s wireless equipment list. -Detailed SSAA/SSP or database may be used. 2. Verify all minimum data elements listed above are included in the equipment list. 3. Verify all wireless devices used at the site, including infrared mice/keyboards, are included. 4. Verify procedures are in place for ensuring the list is kept updated. 5. Note the date of last update and if the list has many inaccuracies. Mark as a finding if the equipment list does not exist, all data elements are not tracked, or the list is outdated. This check applies to: - Wireless networking devices, such as access points, bridges, and switches. - WLAN client devices, such as laptop computers and PDAs if used with WLAN NICs. - Wireless peripherals, such as Bluetooth, and Infrared mice and keyboards, communications devices, such as VoIP, cellular/satellite telephones, and Broadband NICs, and non-wireless CMDs that store, process, or transmit DoD information.
Maintain a list of all DAA-approved WLAN devices. The list must be updated periodically and will contain the data elements required by the STIG policy.
Review the site security plan. 1. Wireless network devices, such as access points, laptops, CMDs, and wireless peripherals (keyboards, pointers, etc.) using a wireless network protocol, such as Bluetooth, 802.11, or proprietary protocols must be documented in the site security plan. 2. A general statement in the site security plan permitting the various types of wireless network devices used by the site is acceptable rather than a by-model listing, for example, “wireless devices of various models are permitted as long as they are configured in accordance with the Wireless STIG”. Mark as a finding if a DAA-approved site security plan does not exist or if it has not been updated.
Ensure devices connecting directly or indirectly (data synchronization) to the network are added to the site's site security plan. (For example, it may say wireless devices of various models are permitted but only when configured in accordance with the Wireless STIG or other such specified restriction.)
For SME PED: This requirement is not applicable. Work with the traditional reviewer or interview the IAO or SM. Determine if the site SCIF CSA has approved wireless CMDs in the site SCIFs. Determine if the DAA and site SSO have approved wireless CMDs in site SCIFs. Ask for approval documentation, if approval has been granted. All three entities must grant approval (SCIF CSA, DAA, and SSO). If wireless CMDs in site SCIFs have not been approved, determine if procedures are in place to prevent users from bringing CMDs into SCIFs and if users are trained on this requirement. Posted signs are considered evidence of compliance. If wireless devices have been approved for use in SCIFs: - Determine if site has written procedures that describe what type of CMDs and under what type of conditions (i.e., turned off, SCIF mode enabled, etc.) approval is granted. - Users must receive proper training on the handling of wireless devices in SCIFs. Mark this as a finding if: - Wireless devices are allowed in site SCIFs without required approvals. - Required procedures are not in place. - Required user training has not been documented.
Ensure users are trained on the need to comply with this requirement and/or site procedures document the policy. Alternately, this requirement can be included in the site User Agreement.
Detailed Policy Requirements: Note: This requirement does not apply to the SME PED. Note: This requirement does not apply to the SWLAN SecNet 11/54 equipment or other NSA approved classified WLAN systems. The IAO will ensure wireless devices are not operated in areas where classified information is electronically stored, processed, or transmitted unless: - Approved by the DAA in consultation with the Certified TEMPEST Technical Authority (CTTA). - The wireless equipment is separated from the classified data equipment at the minimum distance determined by the CTTA and appropriate countermeasures, as determined by the CTTA, are implemented. Check Procedures: Review documentation. Work with the traditional security reviewer to verify the following: 1. If classified information is not processed at this site, mark as not a finding. 2. If the site has a written procedure prohibiting the use of wireless devices in areas where classified data processing occurs, mark as not a finding. Ask for documentation showing the CTTA was consulted about operation and placement of wireless devices. Acceptable proof would be the signature or initials of the CTTA on the architecture diagram or other evidence of coordination. IAW DoD policy, the CTTA must have a written separation policy for each classified area. 3. Review written policies, training material, or user agreements to see if wireless usage in these areas is addressed. 4. Verify proper procedures for wireless device use in classified areas is addressed in training program. Mark as a finding if any of the following are found: - CTTA has not designated a separation distance in writing. - DAA has not coordinated with the CTTA. - Users are not trained or made aware (using signage or user agreement) of procedures for wireless device usage in and around classified processing areas.
- CTTA must designate a separation distance in writing. - DAA must coordinate with the CTTA. - Train users or get a signed user agreement on procedures for wireless device usage in and around classified processing areas.
Additional Policy Requirements: The user agreements must include DAA authorized tasks for the mobile device and relevant security requirements, including, but not limited to, the following: 1. DoD CIO Memorandum, “Policy on Use of Department of Defense (DoD) Information Systems Standard Consent Banner and User Agreement,” 9 May 2008 directs the following content will be included in a site User Agreement: STANDARD MANDATORY NOTICE AND CONSENT PROVISION FOR ALL DOD INFORMATION SYSTEM USER AGREEMENTS By signing this document, you acknowledge and consent that when you access Department of Defense (DoD) information systems: - You are accessing a U.S. Government (USG) information system (IS) (which includes any device attached to this information system) that is provided for U.S. Government authorized use only. - You consent to the following conditions: o The U.S. Government routinely intercepts and monitors communications on this information system for purposes including, but not limited to, penetration testing, communications security (COMSEC) monitoring, network operations and defense, personal misconduct (PM), law enforcement (LE), and counterintelligence (CI) investigations. o At any time, the U.S. Government may inspect and seize data stored on this information system. o Communications using, or data stored on, this information system are not private, are subject to routine monitoring, interception, and search, and may be disclosed or used for any U.S. Government-authorized purpose. o This information system includes security measures (e.g., authentication and access controls) to protect U.S. Government interests--not for your personal benefit or privacy. o Notwithstanding the above, using an information system does not constitute consent to personnel misconduct, law enforcement, or counterintelligence investigative searching or monitoring of the content of privileged communications or data (including work product) that are related to personal representation or services by attorneys, psychotherapists, or clergy, and their assistants. Under these circumstances, such communications and work product are private and confidential, as further explained below: - Nothing in this User Agreement shall be interpreted to limit the user's consent to, or in any other way restrict or affect, any U.S. Government actions for purposes of network administration, operation, protection, or defense, or for communications security. This includes all communications and data on an information system, regardless of any applicable privilege or confidentiality. - The user consents to interception/capture and seizure of ALL communications and data for any authorized purpose (including personal misconduct, law enforcement, or counterintelligence investigation). However, consent to interception/capture or seizure of communications and data is not consent to the use of privileged communications or data for personnel misconduct, law enforcement, or counterintelligence investigation against any party and does not negate any applicable privilege or confidentiality that otherwise applies. - Whether any particular communication or data qualifies for the protection of a privilege, or is covered by a duty of confidentiality, is determined in accordance with established legal standards and DoD policy. Users are strongly encouraged to seek personal legal counsel on such matters prior to using an information system if the user intends to rely on the protections of a privilege or confidentiality. - Users should take reasonable steps to identify such communications or data that the user asserts are protected by any such privilege or confidentiality. However, the user's identification or assertion of a privilege or confidentiality is not sufficient to create such protection where none exists under established legal standards and DoD policy. - A user's failure to take reasonable steps to identify such communications or data as privileged or confidential does not waive the privilege or confidentiality if such protections otherwise exist under established legal standards and DoD policy. However, in such cases the U.S. Government is authorized to take reasonable actions to identify such communication or data as being subject to a privilege or confidentiality, and such actions do not negate any applicable privilege or confidentiality. - These conditions preserve the confidentiality of the communication or data, and the legal protections regarding the use and disclosure of privileged information, and thus such communications and data are private and confidential. Further, the U.S. Government shall take all reasonable measures to protect the content of captured/seized privileged communications and data to ensure they are appropriately protected. o In cases when the user has consented to content searching or monitoring of communications or data for personnel misconduct, law enforcement, or counterintelligence investigative searching, (i.e., for all communications and data other than privileged communications or data that are related to personal representation or services by attorneys, psychotherapists, or clergy, and their assistants), the U.S. Government may, solely at its discretion and in accordance with DoD policy, elect to apply a privilege or other restriction on the U.S. Government's otherwise-authorized use or disclosure of such information. o All of the above conditions apply regardless of whether the access or use of an information system includes the display of a Notice and Consent Banner ("banner"). When a banner is used, the banner functions to remind the user of the conditions that are set forth in this User Agreement, regardless of whether the banner describes these conditions in full detail or provides a summary of such conditions, and regardless of whether the banner expressly references this User Agreement. 2. For SME PED, see the SME PED User Agreement template included with the SME PED STIG for specific requirements. 3. DoD sites are required to add the following to all site User Agreements: - The agreement should contain the type of access required by the user (privileged, end-user, etc.). - The agreement should contain the responsibilities, liabilities, and security measures (e.g., malicious code detection training) involved in the use of the wireless remote access device. - Incident handling and reporting procedures will be identified along with a designated point of contact. - The remote user can be held responsible for damage caused to a Government system or data through negligence or a willful act. - The policy should contain general security requirements and practices, which are acknowledged and signed by the remote user. - If classified devices are used for remote access from an alternative work site, the remote user will adhere to DoD policy in regard to facility clearances, protection, storage, distributing, etc. - Government owned hardware and software is used for official duties only. The employee is the only individual authorized to use this equipment. - User agrees to complete required wireless device training annually. 4. For approved smartphone and tablet devices add to all User Agreements: - Only approved Bluetooth headsets/handsfree devices will be used. Check Procedures: 1. Inspect a copy of the site’s user agreement. 2. Verify the user agreement has the minimum elements described in the STIG policy. 3. Select 10 names of assigned site personnel and verify they have a signed user agreement on file for assigned wireless equipment (e.g., wireless laptop, smartphone, tablet, etc.). Mark as a finding if site user agreements do not exist or are not compliant with the minimum requirements. For SME PED: - Verify the Terminal Administrator (TA) has users reaffirm their User Agreement at least once every 12 months. Review the dates that site User Agreements were signed.
Implement User Agreement with required content. Have all users sign a User Agreement.
Detailed Policy Requirements: For WLAN Access Points: If the WLAN infrastructure network device (access point, bridge, WLAN switch/gateway/controller, etc.) is used in an unprotected public area, the following security controls are required. (The site Physical Security Officer should make a determination if a WLAN device installation location should be considered to be an unprotected public area.) One of the following security controls is required: - The WLAN device must be physically secured by placing it inside a securely mounted, pick-resistant, and lockable enclosure. - The encryption keys stored on the device must be encrypted on the device using an encryption module validated as meeting FIPS 140-2 Level 2, at a minimum. Check Procedures: The NSO will ensure all network devices (i.e., IDS, routers, servers, Remote Access System (RAS), firewalls, WLAN access points, etc.) are located in a secure room with limited access or otherwise secured to prevent tampering or theft. For WLAN Access Points: Determine if the WLAN network component of the WLAN system (e.g., access point or bridge) is installed in an unprotected public area where unauthorized personnel can get access to the device. The Physical Security Reviewer may be able to assist in this determination. If yes, the following requirements apply. Note: Access points installed above ceiling tiles in a controlled access area or installed 30 feet above the ground in a controlled access hanger can be considered to be installed in a protected non-public area. The site Physical Security Officer should make a determination if a WLAN device installation location should be considered to be in an unprotected public area. Determine if the WLAN device has been validated as meeting FIPS 140-2 Level 2, at a minimum, or physically secured by placing it inside a securely mounted, pick-resistant, and lockable enclosure. Mark as a finding if the requirements above are not met. For SME PED: During SRR walkthrough inspection, visually confirm the SME PED servers and network equipment (such as, HAIPE) are installed in secured areas.
Place all network devices (i.e., Intrusion Detection System (IDS), routers, Remote Access System (RAS), firewalls, etc.) in a secure room with limited access or otherwise secured to prevent tampering or theft. WIR0225 provides physical security requirements for classified WLAN systems.
Interview the site IAM and IAO and determine if personally owned or contractor owned CMDs (Bring Your Own Device – BYOD) are used at the site to transmit, receive, store, or process DoD information or connect to DoD networks. Mark as a finding if personally owned or contractor owned CMDs (Bring Your Own Device – BYOD) are used to transmit, receive, store, or process DoD information or connect to DoD networks.
Prohibit use of personally owned or contractor owned CMDs (Bring Your Own Device – BYOD) at the site to transmit, receive, store, or process DoD information or connect to DoD networks.
Interview the IAO and inspect a sample of laptops/PCs (check about 10% if possible, with priority to laptops) used at the site for classified data processing. 1. Ask if there are laptops/PCs used to process classified information and have embedded wireless NICs. No embedded wireless NICs are allowed, including WLAN, Bluetooth, WMAN, cellular, etc. 2. The NIC should be physically removed. Using methods, such as tape or software disabling are not acceptable. Interview the IAO and determine if the site either bought laptops without wireless NICs (Wi-Fi, Bluetooth, WiMax, etc.) or physically removed the NICs from laptops. Verify the site has procedures in place to ensure laptops with wireless NICs are not used for classified data processing. Mark as a finding if site is using embedded wireless NICs. If this is a finding, recommend to the DAA this is a critical finding requiring immediate action.
Ensure computers with embedded wireless NICs that cannot be removed and are not used to transfer, receive, store, or process classified information.
