DTBI635 - Internet Explorer Processes for Restrict File Download must be enforced (Explorer).

Information

In certain circumstances, web sites can initiate file download prompts without interaction from users. This technique can allow web sites to put unauthorized files on user's 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.

Solution

Set the policy value for Computer Configuration -> Administrative Templates -> Windows Components -> Internet Explorer -> Security Features -> Restrict File Download -> 'Internet Explorer Processes' to 'Enabled'.
