Anattacker might target a URL containing a common misspelling, for example, orotherwise similar to a legitimate URL. Such a site could be used to distribute malwareto users before traditional filters can be updated to reflect these sites as malicious.When Websense security researchers detect that a site includes a potential threat, thesite is added to the Extended Protection category until researchers are 100% confidentof the site’s final categorization.TRITON - Web Security Help | Web Security Solutions | Version 7.7.xRelated topics: Assigning categories to risk classes, page 408 Presentation reports, page 135 Investigative reports, page 156The Websense Master Database groups categories into risk classes.
