Vulnerability discussion

Without authenticating devices, unidentified or unknown devices may be introduced, thereby facilitating malicious activity.For distributed architectures (e.g., service-oriented architectures), the decisions regarding the validation of authentication claims may be made by services separate from the services acting on those decisions.In such situations, it is necessary to provide authentication decisions (as opposed to the actual authenticators) to the services that need to act on those decisions.This requirement applies to applications that connect either locally, remotely, or through a network to an endpoint device (including but not limited to: workstations, printers, servers (outside a datacenter), VoIP Phones, VTC CODECs).Gateways and SOA applications are examples of where this requirement would apply.End point devices are not:Client desktop workstations only offer browser-based web application access where the user authenticates at the app layer.Device authentication is a solution enabling an organization to manage devices. It is an additional layer of authentication ensuring only specific pre-authorized devices can access the system.

Check content

Review the application documentation, implementation documentation and interview the application administrator. Identify if the application utilizes Web Services/Service-Oriented Architecture (SOA). Using the web services framework that has been implemented, have the application administrator identify the remote devices allowed to communicate to the service provider. If the application is designed to provide end-user, interactive application access only and does not use web services or allow connections from remote devices, this requirement is not applicable. Identify the authentication mechanism used to authenticate the remote consumers/devices. Commonly available authentication methods are Client Certificate Authentication and Basic Authentication. The Basic Authentication method provides insufficient protection for authentication sessions and is not allowed. If no authentication mechanism is used to authenticate remote service consumers/devices, or if Basic Authentication is used to authentication remote service consumers/devices, this is a finding.

Fix text

Configure the application to authenticate all network connected endpoint devices/service consumers before establishing connections.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
