Description
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.

Who does this work

5 NICE work roles and 5 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-223114r879587_chk)

The policy value for Computer Configuration -> Administrative Templates -> Windows Components -> Internet Explorer -> Security Features -> Restrict File Download -> 'Internet Explorer Processes' must be 'Enabled'. Procedure: Use the Windows Registry Editor to navigate to the following key: HKLM\Software\Policies\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_RESTRICT_FILEDOWNLOAD Criteria: If the value "explorer.exe" is REG_SZ = 1, this is not a finding.

Fix Text (F-24775r428893_fix)

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