Discussion

Without authenticating devices, unidentified or unknown devices may be introduced, thereby facilitating malicious activity. Bidirectional authentication provides stronger safeguards to validate the identity of other devices for connections that are of greater risk. 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. A local connection is any connection with a device communicating without the use of a network. A network connection is any connection with a device that communicates through a network (e.g., local area or wide area network, Internet). A remote connection is any connection with a device communicating through an external network (e.g., the Internet). Because of the challenges of applying this requirement of a large scale, organizations are encouraged to only apply the requirement to those limited number (and type) of devices that truly need to support this capability.

Review the ArcGIS for Server configuration to ensure that the application authenticates all network connected endpoint devices before establishing any connection. Substitute the target environment’s values for [bracketed] variables.

Within IIS >> within the [“arcgis”] application >> Authentication >> Verify that “Windows Authentication” is “Enabled”.
Verify that “Anonymous Authentication” is “Disabled”.
If “Windows Authentication” is not enabled, or “Anonymous Authentication” is enabled, this is a finding.
