"It recognizes that a Web site is doing something that looks inappropriate & and simply blocks it without giving the user a whole lot of notice," says Nash. When it recognizes an XSS in a request, IE8 blocks the malicious script from executing. The XSS Filter, new in IE8, can monitor all requests and responses flowing through a browser. What's most unsettling about XSS: everything looks normal to the user while unauthorized access is being given to a hacker and sensitive data is being stolen. XSS allows malicious code to be injected into Web pages that can lead to information disclosure and identity theft. "The SmartScreen Filter will recognize them as a hoax and alert users that they should not go there."Ĭross-site scripting (XSS) attacks are some of the leading exploits against Web users. "A lot of Web sites try to make themselves look like anti-spyware sites when in fact they are downloading spyware," Nash says. One of the major threats to users, adds Nash, are bad sites disguised as good sites. It does give the option "Disregard and continue (not recommended)" but IT managers can remove this option to "keep users from having to make a decision of trust without the knowledge to make a decision of trust," says Nash. When it is enabled and you try to visit a site that is considered unsafe, a Web page with a red screen appears recommending you do not continue to the Web site. The user has the choice to enable or disable SmartScreen, though Nash highly recommends it be enabled. The SmartScreen Filter blocks imposter sites that may download malicious software. The SmartScreen Filter has been reinforced in IE8 to combat the increasingly complex ways that hackers and malicious sites send viruses and steal personal information. He adds that IE8 will automatically restore a tab that has crashed once it has identified the problem and then return you to the site you were on before the crash. "In the past, if there was a bug in a Web page and it crashed it would cause the entire browser or even the operating system to crash," says Nash.
If a Web site does crash in one tab then only that tab is affected, while the browser itself and other open tabs carry on as if nothing has happened. Microsoft promises that Internet Explorer 8 has been architected so that crashes will be limited. Everybody has had to deal with a crashing browser, resulting in lost data and a reboot.
