Using Phishing Protection
Creating a site that masquerades as a legitimate secure site but actually steals your login
information is called phishing (or spoofi ng ). Phishing employs many tactics, which are
evolving all the time. For example, you may get an email that claims to be from your bank,
ISP, and so forth, asking you to follow a link to its site to update your details. The email
looks authentic, and when you follow the link, the site looks very much like the site of the
bank or ISP—except the page probably isn't secure, and some links on the page may not be
operational.
Most browsers have some phishing protection built-in. That's part of the role of the
different-colored background of the Address bar in Internet Explorer, for example; if it's green,
that indicates the phishing fi lter has determined the site is legitimate. A yellow background
indicates caution because there is a problem with the verifi cation; a red background indicates
that this site probably isn't what it seems to be and should be avoided.
In Internet Explorer, the phishing fi lter is called the SmartScreen fi lter , and it can be
enabled or disabled. Normally you should leave it enabled, because it provides information
and doesn't prevent you from doing anything. Its assessment is fairly accurate, as well. The
only drawback (and it's very minor) is that if you leave automatic checking turned on, the
browser checks every page you visit, resulting in slightly slower browser performance. If
you seldom visit secure sites and you want to check only the specifi c sites about which you
have a question, you can turn off this feature. Exercise 9.9 shows you how to confi gure the
SmartScreen fi lter in Internet Explorer 9.
