User Entries to Server List must be disallowed.
An XCCDF Rule
Description
<VulnDiscussion>If users are able to manually enter the addresses of servers that are not approved by the organization, they could use servers that do not meet your organization's information security requirements, which could cause sensitive information to be at risk. By default, when users create a meeting workspace, they can choose a server from a default list provided by administrators or manually enter the address of a server that is not listed.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility>System Administrator</Responsibility><Responsibility>Information Assurance Officer</Responsibility><IAControls></IAControls>
