Unsupported versions will lack security enhancements as well as support provided by the vendors to address vulnerabilities. The system administrator must monitor IAVM, OS, or OEM patch or vulnerability notices for the remote access, VPN, or communications appliance(s). Patches, upgrades, and configuration changes should be tested to the greatest extent possible prior to installation. The vendor may be consulted to determine if the specific device is vulnerable. If the vendor does not recommend installing a patch or upgrade, and has stated that the device is not vulnerable, the administrator will retain this documentation.System AdministratorInformation Assurance OfficerECSC-1, VIVM-1
Checks: C-21324r1_chk

Verify remote access gateway release and maintenance level. Research the vendor's vulnerability list and current version/revision. This can be obtained on the vendor's support page of their website.

Fix: F-19140r1_fix

A centralized policy manager provides a consistent security policy, particularly in environments with multiple remote access devices such as multiple VPNs or RAS devices. This is a best practice for centralized management in networks with multiple remote access gateways or products. Use a single remote access policy server or configure a centralized access server which serves this purpose.Information Assurance OfficerNetwork Security OfficerEBRU-1
Checks: C-22224r1_chk

Review the configuration of the remote access device (RAS/VPN). Verify the remote access policy is the primary means for configuring access control for user access. The centralized remote access policy should apply to all remote access devices so that there is a consistent security policy. Remote access portals and network extension are also handled in this access control policy. NOTE: Portal configuration and network extension configuration is handled in the access control policy.

Device authentication must be performed at the perimeter or on a subnet separated from the trusted internal enclave. User authentication ensures the user is authorized for access. However, user authentication does not mitigate the risk from an improperly configured client device. Devices must be tested for policy compliance and assigned a trust level based on the results of a thorough integrity check. This approach checks that devices connecting to the network are authenticated and compliant with network policy prior to allowing access to network resources.Information Assurance OfficerECSC-1
Checks: C-22304r1_chk

Have the site representative display the evidence of compliance. This feature must be implemented using a central access policy such as in a gateway or access control appliance. - Government-owned and managed endpoints; - Personally-owned but managed endpoints; - Unmanaged endpoints such as public kiosks or personal computers should limited access to Web-based applications; - Privileged or Administrative access; - Endpoints compliant with DoD required security configurations such as firewalls, antivirus, etc. - Endpoints not compliant with DoD required security configurations such as firewalls, antivirus software, etc.

Fix: F-19251r1_fix

Separate the users by conditions and assigned resources based on required minimum security conditions.

b
If a policy assessment server or service is used as part of an automated access control decision point (to accept non-DoD owned and/or managed remote endpoints to the network), only devices that are both authenticated to the network and compliant with network policies are allowed access.

In this STIG, a managed device is defined as a device that has installed software (i.e. an agent) that allows the device to be managed and queried from a remote server. Thus, an unmanaged device does not have a pre-installed agent which has been obtained from and configured by an approved DoD source. A device is also considerd unmanaged if the authorized agent is not operating properly and cannot communicate with the server. Devices that are both non-GFE and unmanaged cannot be used. To be authenticated to the network, the authentication information must be pre-configured by the site's system administrator and the device and the user must be authorized by the DAA for access to the system. Trusted computing environments require a process for ensuring that users and devices are authenticated and authorized. In certain environments such as a development network, unmanaged devices may be justified by government policy or the mission. Automated policy assessment may be implemented in various ways to increase trust and manage the risk posed by these guest devices. Information Assurance OfficerECSC-1
Checks: C-22462r1_chk

Verify that the device filter setting of the network authentication appliance is configured to force endpoint devices on the untrusted subnetwork to authenticate when attempting to access the network. In an environment where unmanaged devices are allowed remote access, devices on the untrusted side will not be set to bypass authentication. Filter lists may be set to use MAC, IP, or subnet address, and should automatically assign user roles to devices. Filters will not be configured to allow devices to bypass authentication or posture assessment.

Fix: F-19390r1_fix

Ensure the policy assessment device is configured to authenticate the endpoint devices before allowing access unto the trusted network.

If endpoint devices used to access restricted networks and systems are not compliant with security policies and able to pass policy assessment then privileged information and systems may be at immediate risk. Devices are government owned (GFE), contractor owned, or personally owned. Devices are categorized as government owned (GFE), contractor owned, or personally owned. A personally-owned device is not managed, owned, or leased by the government. Personally owned devices do not meet DoD security standards for privileged access. This type of access from an untrusted device puts the network at immediate risk since these devices may have ensured confidentiality and integrity requirements. These devices may be managed devices. However, even when subjected to policy assessment, personally owned devices are not allowed for processing classified or for remote access to privileged data or functions. The intention is to allow approved and limited usage (e.g., for email). However, note that a policy assessment solution must be in place for all unmanaged devices to enter trusted zones. Contractor owned endpoints are provided in compliance with a government contract to perform management services. These endpoints must be STIG compliant using the OS STIG and other applicable STIGs and must follow DoD requirements for remaining compliant. The configuration and connection method for privileged access must also comply with government confidentiality and integrity requirements. Thus, the configuration of devices must be approved by the government as STIG compliant and kept up to date.

Detailed Policy Requirements: The ISSO 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. - User authentication and content encryption requirements. - Enabling wireless interfaces only when needed. - Enable VPN connection to the DoD network immediately after establishing a wireless connection (using an approved VPN client). - 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 ISSO. 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. If wireless remote access users have not received required training, this is a finding.

Detailed Policy Requirements: A site's Remote Access Policy will be written and signed by the site AO, Commander, Director, or other appropriate manager. Recommend the policy includes required security controls for the DoD-owned/operated wireless client (PDA, smartphone, or tablet): - Device unlock password requirements. - Client software patches kept up to date - Internet browsing through enterprise Internet gateway. - Device security policy managed by centrally-managed policy manager. - Procedures after client is lost, stolen, or other security incident occurs. - 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. --Avoid connecting to WLAN access points with WEP security due to the security issues with this protocol. - 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 ISSO 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 AO, Commander, Director, or other appropriate managers. If a wireless remote access policy does not exist or is not signed, this is a finding.

Fix: F-27725r4_fix

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.System AdministratorECWN-1

This requirement applies to mobile operating system (OS) CMDs. Work with traditional reviewer to review site’s physical security policy. Verify the site addresses CMDs with embedded cameras. If there is no written physical security policy outlining whether CMDs with cameras (still and video) are permitted or prohibited on or in the DoD facility, this is a finding.

Fix: F-27726r5_fix

Publish a site physical security policy that includes a statement if CMDs with cameras (still and video) are permitted or prohibited on or in the DoD facility.
