Assessment Title

Rule Text

Safe Browsing must be enabled,

Description

Discussion Text

Allows you to control whether Google Chrome's Safe Browsing feature is enabled and the mode it operates in. If this policy is set to 'NoProtection' (value 0), Safe Browsing is never active. If this policy is set to 'StandardProtection' (value 1, which is the default), Safe Browsing is always active in the standard mode. If this policy is set to 'EnhancedProtection' (value 2), Safe Browsing is always active in the enhanced mode, which provides better security, but requires sharing more browsing information with Google.

Checks

DISA STIG (Manual Reference)

Universal method: 
 1. In the omnibox (address bar) type chrome://policy 
 2. If SafeBrowsingProtectionLevel is not displayed under the Policy Name column or it is not set to 1 or 2 under the Policy Value column, then this is a finding.

Windows method:
 1. Start regedit
 2. Navigate to HKLM\Software\Policies\Google\Chrome\
 3. If the SafeBrowsingProtectionLevel value name does not exist or its value data is not set to 1 or 2, then this is a finding.

Remediation

Windows group policy:
 1. Open the “group policy editor” tool with gpedit.msc
 2. Navigate to Policy Path: Computer Configuration\Administrative Templates\Google\Google Chrome\Safe Browsing Settings
 Policy Name: Safe Browsing Protection Level
 Policy State: Enabled
 Policy Value: StandardProtection or EnhancedProtection
