Select Log to record attempts to access web pages that occur when the external content filtering database is unavailable. Select this check box to restrict access to all site categories listed below. Select this check box to clear the selected categories below. These are categories of web pages that are known to pose a threat to users or their computers. This category includes pages that are designed to appear as a legitimate bank or retailer with the intent to fraudulently capture sensitive data (i.e. credit card numbers, pin numbers). This category includes pages which distribute spyware and other malware. Spyware and malware are defined as software which takes control of your computer, modifies computer settings, collects or reports personal information, or misrepresents itself by tricking users to install, download, or enter personal information. This includes drive-by downloads; browser hijackers; dialers; intrusive advertising; any program which modifies your homepage, bookmarks, or security settings; and keyloggers. It also includes any software which bundles spyware (as defined above) as part of its offering. Information collected or reported is "personal" if it contains uniquely identifying data, such as e-mail addresses, name, social security number, IP address, etc. A site is not classified as spyware if the user is reasonably notified that the software will perform these actions (that is, it alerts that it will send personal information, be installed, or that it will log keystrokes). Note: Sites rated as spyware should have a second category assigned with them. UAG715 User's Guide 343
