Assessment Title

Rule Text

The configuration of wireless devices using Windows Connect Now must be disabled.

Description

Discussion Text

Windows Connect Now allows the discovery and configuration of devices over wireless. Wireless devices must be managed. If a rogue device is connected to a system, there is potential for sensitive information to be compromised.

How this relates to the STIG checklist: STIG vs SCAP benchmark.

Remediation

Configure the policy value for Computer Configuration -> Administrative Templates -> Network -> Windows Connect Now -> "Configuration of wireless settings using Windows Connect Now" to "Disabled".
