A peek at IE7's new security
PC World | at | by Mike
Microsoft has revealed some of the security changes to the upcoming Internet Explorer 7 and Windows Vista--changes that could cause trouble for some Web sites.
One key change is that Explorer will disable SSLv2, an older version of the Secure Sockets Layer protocol. SSL is used to carry out secure Web transactions. In its place, Explorer 7 will continue to support SSLv3 and will enable Transport Layer Security v1, a newer protocol.
The change means that sites currently requiring SSLv2 will need to allow either SSLv3 or TLSv1, Microsoft said on its Internet Explorer Weblog, part of the Microsoft Developer Network.
