Internet filtering is a way of blocking access to these types of Web sites. Bess Internet filtering solution is flexible and allows parents, educators, and employers to override the system, when necessary, by using a separate password. One approach is client-based software products which, when loaded onto an individual computer, check specific Web site requests against a database of Web sites deemed inappropriate and disallow the retrieval of the content. There are several drawbacks to client-based products. First, users must load software onto the individual computer.
Updates are usually available, but continually updating is troublesome to the user.
They are often easy to bypass because they are loaded on the same computer they're protecting. The approach we chose to use is server-based filtering which resides at the network level, so that each computer does not have to have software loaded. This is the most practical approach, users automatically receive the most updated list of blocked sites daily. We at Eclipse feel that N2H2, developers of Bess , is the safest, most effective solution for our customers.
