13Refine Filtering PoliciesTRITON - Web Security Help | Web Security Solutions | Version 7.7.xAt it’s simplest, Internet usage filtering requires a single policy that applies onecategory filter and one protocol filter 24 hours a day, 7 days a week. Websensesoftware offers tools, however, for going far beyond this basic filtering, to achieveprecisely the level of granularity you need to manage Internet usage. You can:Create limited access filters to block access to all but a specified list of sites forcertain users (see Restricting users to a defined list of URLs, page 255).Create custom categories to redefine how selected sites are filtered (see Workingwith categories, page 262).Recategorize URLs to move specific sites from their default, Master Databasecategory to another Websense-defined or custom category (see Redefiningfiltering for specific sites, page 268).Implement bandwidth restrictions, blocking users from accessing otherwisepermitted categories and protocols when bandwidth usage reaches a specifiedthreshold (see Using Bandwidth Optimizer to manage bandwidth, page 279).In Websense Web Security Gateway Anywhere environments, bandwidth-basedrestrictions are not enforced for hybrid filtering users.Define keywords used to block sites in otherwise permitted categories whenkeyword blocking is enabled and activated (see Filtering based on keyword, page266).Define file types used to block the download of selected types of files fromotherwise permitted categories when file type blocking is activated (see Managingtraffic based on file type, page 282).Restricting users to a defined list of URLsTRITON - Web Security Help | Web Security Solutions | Version 7.7.xRelated topics: Limited access filters and filtering precedence, page 256 Creating a limited access filter, page 257 Editing a limited access filter, page 258TRITON - Web Security Help 255
