Phishing
A phish is an email message that falsely claims to be from an established or legitimate
enterprise. The message encourages recipients to click on a link that will redirect their
browsers to a fraudulent Web site. Once there, the user is asked to update personal
information such as passwords, social security numbers, and credit card numbers,
which will be used for identity theft. InterScan Gateway Security Appliance provides
tools for handling known phishing sites and for adding others to a list of offenders.
Spam
Spamming is the misuse of electronic communications media to send unsolicited bulk
messages. The most common form of spam is delivered in email as a form of com-

email and on the Web using a database of known spammers and content filters.

of a third party, usually for commercial gain. Typical uses of spyware include the
delivery of unsolicited pop-up advertisements, the theft of personal information
(including financial information such as credit card numbers), the monitoring of
Web-browsing activity for marketing purposes, and the routing of HTTP requests to
advertising sites.
Trojans
A Trojan is a malicious program that masquerades as a harmless application. Unlike
viruses, Trojans do not replicate, but they can be just as destructive. An application
that claims to rid your computer of viruses when it actually introduces viruses onto
your computer is an example of a Trojan. Trojans do not infect files; therefore, they
