Automatic Call Answering to the Hardware Management Console must be disabled.
An XCCDF Rule
Description
<VulnDiscussion>Automatic Call Answering to the Hardware Management Console allows unrestricted access by unauthorized personnel and could lead to a bypass of security, access to the system, and an altering of the environment. This would result in a loss of secure operations and impact the integrity of the operating environment, files, and programs. Note: Dial-in access to the Hardware Management Console is prohibited. Also, many newer processors (e.g., zEC12/zBC12 processors) will not have modems. If there is no modem, this check is not applicable.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
