1. Request copies of written AO approval documentation for wireless/mobile devices used by the site. 2. Verify AO approval for wireless/mobile devices in use at the site. Note: The AO approval for wireless/mobile systems does not need to be documented separately from other AO approval documents for the site network, as long as the approval documents list the wireless/mobile systems in use at the site. For example, if a site network ATO lists the wireless system, the ATO meets the requirements of this check. If the AO has not approved all wireless/mobile devices used at the site, this is a finding.
Obtain AO approval prior to wireless systems being installed and used.
Detailed Policy Requirements: Note: This requirement does not apply to NSA-approved classified WLAN systems. The ISSO will ensure wireless devices are not operated in areas where classified information is electronically stored, processed, or transmitted unless: - Approved by the Authorizing Official (AO) 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. If wireless devices are used in or around classified processing areas but the CTTA has not designated a separation distance in writing, the AO has not coordinated with the CTTA, or users are not trained or made aware (using signage or user agreement) of procedures for wireless device usage in and around classified processing areas, this is a finding.
Central Computer and Telecommunication Agency (CTTA) must designate a separation distance in writing. AO 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 Authorizing Official (AO) 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,” 09 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. 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. 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.). If site user agreements do not exist or are not compliant with the minimum requirements, this is a finding.
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 that have embedded wireless NICs. No embedded wireless NICs are allowed, including WLAN, Bluetooth, WMAN, cellular, etc. unless the wireless radios have been physically disabled or the wireless system has been certified via the DoD CSfC program. 2. The NIC should be physically removed or physically disabled. Using methods such as tape or software disabling is not acceptable. Interview the ISSO and determine if the site either bought laptops without wireless NICs (Wi-Fi, Bluetooth, WiMax, etc.) or physically removed or disabled the NICs from laptops. Verify the site has procedures in place to ensure laptops with wireless NICs are not used for classified data processing unless the NICs have been physically disabled or the wireless system is CSfC certified. If laptops or other computers are used to process classified information and have a wireless NIC installed and the NIC is not physically disabled or the system is not CSfC certified, this is a finding. If this is a finding, recommend to the AO that 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 unless the NICs have been physically disabled or the wireless system is CSfC certified.
