Internet Explorer Processes for Restrict File Download must be enforced (Explorer).
An XCCDF Rule
Description
<VulnDiscussion>In certain circumstances, websites can initiate file download prompts without interaction from users. This technique can allow websites to put unauthorized files on users' hard drives if they click the wrong button and accept the download. If you configure the Restrict File Download\Internet Explorer Processes policy setting to "Enabled", file download prompts that are not user-initiated are blocked for Internet Explorer processes. If you configure this policy setting as "Disabled", prompting will occur for file downloads that are not user-initiated for Internet Explorer processes. Note: This setting is configured as "Enabled" in all environments specified in this guide to help prevent attackers from placing arbitrary code on users' computers.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
