WebSENSE is used for any organization that needs to provide Internet access, but is concerned with access to unauthorized sites.

WebSENSE allows you to control or monitor Internet activity.

With WebSENSE, organizations can guard against user downtime caused by employees surfing sites that are not work-related and misusing network resources.

WebSENSE works on Windows NT and Solaris.

WebSENSE is software that provides integrated, URL filtering for the PIX Firewall, giving network administrators the ability to effectively monitor and control network traffic. WebSENSE is used to block specific URLs because the PIX Firewall cannot. WebSENSE determines whether to block or permit specific URLs based on its configuration and the Master Database. The WebSENSE configuration is the filtering rules you set in WebSENSE. The Master Database is a database of URLs to block. This database is maintained and updated daily by the WebSENSE corporate office. You can choose when, and if you want, to download the URLs from this database.

WebSENSE is useful because between the hours of 9 a.m. and 5 p.m.:

■ 30 to 40 percent of Internet surfing is not business related.

■ 70 percent of all Internet porn traffic occurs.

■ More than 60 percent of online purchases are made. The following are characteristics of WebSENSE:

■ Hosted on Windows NT or Solaris platform

■ Located inside or on the perimeter network

■ Highly scalable architecture

■ Outbound database and lookup processing minimizes impact on firewall performance and security

■ Multiple servers can be used to increase capacity

■ Has 30 categories of filters

■ Is updated daily (adding up to 5,500 sites per week)

When the PIX Firewall receives a request to access a URL from users, it queries WebSENSE to determine whether or not to return the requested URL. WebSENSE checks its configurations and the Master Database to determine whether the URL should be blocked. If the URL should be blocked, WebSENSE displays either the standard blocking message or directs the user requesting the URL to a specified web site.
