The IAO and the site wireless device administrator must ensure all wireless remote access users receive training on the following topics before they are authorized to access a DoD network via a wireless remote access device:
- Maintaining physical control of the device
- Reducing exposure of sensitive data
- Backing up data frequently
- User authentication, anti-virus, personal firewall, and content encryption requirements
- Enabling wireless interfaces only when needed
- Enable VPN connection to the DoD network immediately after establishing a wireless connection
- All Internet browsing will be done via the VPN connection to the DoD network
- No split tunneling of VPN
- Locations where wireless remote access is authorized or not authorized (i.e., home, airport, hotel, etc.)
- Wireless client configuration requirements
- Use of WPA2 Personal (AES) on home WLAN
- Home WLAN password and SSID requirements - Discontinue the use of devices suspected of being tampered with and notify the site IAO.
For iOS devices, add:
-User should select “Forget this Network” while still in physical range. (This prevents the iPhone from automatically joining networks later that may share the same SSID. The user will not be able to “forget” individual networks when out of range and will have to reset all network settings.)
Check Procedures:
Review site wireless device and/or IA awareness training material to verify it contains the required content.
Note: Some training content may be listed in the User Agreement signed by the user.
Verify site training records show authorized wireless remote access users received required training and training occurred before the users were issued a device. Check training records for approximately five users, picked at random. Mark as a finding if training material does not contain the required content or if wireless remote access users have not received required training.
Site has wireless remote access policy<GroupDescription></GroupDescription>WIR-WRA-002The site must have a Wireless Remote Access Policy signed by the site DAA, Commander, Director, or other appropriate authority. <VulnDiscussion>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.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SecurityOverrideGuidance></SecurityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>System Administrator</Responsibility><IAControls>ECWN-1</IAControls>Publish required policy.Detailed Policy Requirements:
A site's Remote Access Policy will be written and signed by the site DAA, Commander, Director, or other appropriate manager. Recommend the policy includes required security controls for the DoD-owned/operated wireless client (laptop or PDA):
- Device unlock password requirements
- Anti-virus application
- Personal firewall
- Client software patches kept up to date - Internet browsing though enterprise Internet gateway
- Device security policy managed by centrally-managed policy manager
- Anti-spyware app (recommended)
- Procedures after client is lost, stolen, or other security incident occurs
- Host-based Wireless Intrusion Detection and Prevention System (WIDPS)/monitor WIDPS
- Configuration requirements of wireless client - Home WLAN authentication requirements.
- Home WLAN SSID requirements.
- Separate WLAN access point required for home WLAN
- 8+-character authentication password required for home WLAN.
- Use of third-party Internet portals (kiosks) (approved or not approved)
- Use of personally-owned or contractor-owned client devices (approved or not approved)
- Implementation of health check of client device before connection is allowed
- Places where remote access is approved (home, hotels, airport, etc.)
- Roles and responsibilities:
--Which users or groups of users are and are not authorized to use organization's WLANs
--Which parties are authorized and responsible for installing and configuring APs and other WLAN equipment
- WLAN infrastructure security:
--Physical security requirements for WLANs and WLAN devices, including limitations on the service areas of WLANs
--Types of information that may and may not be sent over WLANs, including acceptable use guidelines
- WLAN client device security:
--The conditions under which WLAN client devices are and are not allowed to be used and operated.
--Standard hardware and software configurations that must be implemented on WLAN client devices to ensure the appropriate level of security.
--Limitations on how and when WLAN client’s device may be used, such as specific locations.
- Guidelines on reporting losses of WLAN client devices and reporting WLAN security incidents
- Guidelines for the protection of WLAN client devices to reduce theft
Check Procedures:
Interview the IAO and/or the site wireless device administrator and determine if the site has a wireless remote access policy (or a wireless section in a general remote access policy). Verify the policy has been signed by the site DAA, Commander, Director, or other appropriate managers. Mark as a finding if a wireless remote access policy does not exist or is not signed.
Wireless remote access included in SSP<GroupDescription></GroupDescription>WIR-WRA-003If wireless remote access is approved for use, the site's SSP must include wireless remote access equipment and locations (site network Wi-Fi, home, hotel, public hotspots, etc.) approved for site personnel.<VulnDiscussion>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.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SecurityOverrideGuidance></SecurityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>Information Assurance Officer</Responsibility><IAControls>ECWN-1</IAControls>Update SSP with wireless remote access information.Review the site's SSP and verify it includes a listing of approved wireless remote access equipment and locations (home, hotel, etc.).
