DTBI015 - The IE warning about certificate address mismatch must be enforced.
This parameter warns users if the certificate being presented by the web site is invalid. Since server certificates are used to validate the identity of the web server it is critical to warn the user of a potential issue with the certificate being presented by the web server. This setting aids to prevent spoofing attacks.
Set the policy value for Computer Configuration -> Administrative Templates -> Windows Components -> Internet Explorer -> Internet Control Panel -> Security Page 'Turn on Warn about Certificate Address Mismatch' to 'Enabled'.
