SV-96297r1_rule Chrome must be configured to allow only TLS.

Vulnerability discussion

If this policy is not configured then Google Chrome uses a default minimum version, which is TLS 1.0. Otherwise, it may be set to one of the following values: "tls1", "tls1.1" or "tls1.2".When set, Google Chrome will not use SSL/TLS versions less than the specified version. An unrecognized value will be ignored."tls1" = TLS 1.0"tls1.1" = TLS 1.1"tls1.2" = TLS 1.2

Check content

Universal method: 1. In the omnibox (address bar) type chrome://policy 2. If "SSLVersionMin" is not displayed under the "Policy Name" column or it is not set to "tls1.1", this is a finding. Windows method: 1. Start regedit 2. Navigate to HKLM\Software\Policies\Google\Chrome\ 3. If the "SSLVersionMin" value name does not exist or its value data is not set to "tls1.1", this is a finding.

Fix text

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\Content Settings\ Policy Name: Minimum SSL version enabled Policy State: Enabled Policy Value: TLS 1.1

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
