The guys from the Internet Explorer 7 development team discuss some of the new improvements in IE7 to make HTTPS more secure.
For Internet Explorer 7, the default HTTPS protocol settings will be changed to disable the weaker SSLv2 protocol and to enable the stronger TLSv1 protocol. (Users of IE6 can manually configure these stronger settings by using Internet Explorer’s Tools | Internet Options | Advanced menu.) Hence, by default, IE7 users will negotiate HTTPS connections using SSLv3 or TLSv1.
