The operating system must prevent remote devices that have established a non-remote connection with the system from communicating outside of the communication path with resources in external networks.
An XCCDF Rule
Description
<VulnDiscussion>This control enhancement is implemented within the remote device (e.g., notebook/laptop computer) via configuration settings not configurable by the user of the device. An example of a non-remote communications path from a remote device is a virtual private network. When a non-remote connection is established using a virtual private network, the configuration settings prevent split-tunneling. Split-tunneling might otherwise be used by remote users to communicate with the information system as an extension of the system and to communicate with local resources, such as a printer or file server. The remote device, when connected by a non-remote connection, becomes an extension of the information system allowing dual communications paths, such as split-tunneling, in effect allowing unauthorized external connections into the system. This is a split-tunneling requirement that can be controlled via the operating system by disabling interfaces.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
