Connecting to the Web

The Internet is fundamentally a set of standards (TCP/IP) that operators of independent networks have agreed to use, and a mechanism that allows these independent networks to interconnect for the exchange of data packets.  What is known as the Internet Backbone are independent data communication networks that are interconnected by routers at various national (National Access Points) and regional centres (Regional Exchange Points).   Connecting to the Internet backbone requires a permanent connection (leased-line with minimum T1 line speed) through one of the national or regional packet exchange centres, and assumed to perform various Domain Name and IP Assigned Number services.  For smaller organizations who want to outsource the Domain Name services and/or connect at lower than T1 speeds, Internet Service Providers (ISP) exist as an intermediary.

The World Wide Web exists as a set of protocols (such as HTTP - a subset of TCP/IP and a mark-up language such as HTML) that use the Internet to transport information.  To connect to the Web, one must first connect to the Internet.  For the typical home end-user or small business, the following are the primary methods to temporarily connect to the Internet through an ISP:

  For the larger business, several leased-line options are available:

People with Internet access privileges are expected to be civil in their interaction with others, observe community standards for Net Etiquette and organizational policies.  Unless you are encrypting your messages, assume cyber-snoops may read your messages. 

Why Bother With the Web?

In 1995, nearly 9 out of 10 major corporations use E-Mail and the World Wide Web internally, and almost 45% used Web servers for customers and other external users.

The use of Intranets (a network using the Internet's TCP/IP protocol separated from the public network by a Firewall) is changing the way businesses operate. Both Netscape and Microsoft have white papers describing their vision for the future:

In addition to allowing people to communicate with others on new ways, the Internet is allowing the development of new ways to conduct commerce. Sales of items through the Internet are currently about $518 million, but expected to grow to $6.6 billion by 2000.

See the Electronic Commerce Information Page for additional information.

Screening & Filtering Utilities

The ubiquitous nature of the Internet and its' World Wide Web has made available to all people a plethora of information. Because some parents may consider some of the available information inappropriate for their children, various organizations have begun to build Screening and Filtering systems intended to enable parents to control the material which comes into their homes and may be accessible to their children. (See the Communications Decency Act section of the 1996 Telecommunications Reform Act)

The Platform for Internet Content (PICS) of the World Wide Web Consortium has the purpose of developing technical standards that would support parents' ability to filter and screen material that their children see on the Web. It is intended that when the standards are fully developed, PICS- compliant World Wide Web browsers, USEnet News Group readers, and other Internet applications, will provide parents the ability to choose from a variety of rating services, or a combination of services.

Until the standards are formalized, (see RFC 2057 Source Directed Access Control on the Internet) commercial Net Filters are available that give parents the tools to shield children from the adult-oriented material available on the Internet and its World Wide Web. While Net Filters do not guarantee to block 100% of the objectionable material (there are different definitions for objectionable and the Internet is growing at a brisk rate), these tools can be useful to parents concerned with the development of their children.

Listed below are is a sample of screening and filtering utilities available for under $50. Most also have a monthly subscription fee of less than $5.00 for updates. Most have demo versions that may be downloaded.

Cyber Patrol (http://www.cyberpatrol.com)

Uses a Blocking-Database of sites that one probably would not want a 12 year old to view. The database is broken up into categories, giving parents the flexibility to enforce restrictions based on their own values. Sites to be restricted may be added by parents.

Cybersitter (http://www.solidoak.com/cybersit.htm)

Filters Web, FTP, and News Group sites to block undesirable material. Words or phrases in context may be removed from a page without restricting access to the whole page. May be configured to block, block and report, or just report access to restricted material.

InterGO (http://www.intergo.com)

Includes a Web Browser, search engine, E-Mail, FTP client, Telnet client, a newsreader for News Groups, a spell-checker, and a virus scanner. Allows for individual user IDs with different access ratings for individual users. Uses a Blocking-Database with a rating classification by age group that is editable.

Specs for Kids (tm) (http://www.newview.com)

proactively rates the content of sites on the levels of sex, violence, and 11 other criteria. Unrated sites may be added. Parents may create user profiles to personalize access for each user. An access log is maintained.

Net Nanny (http://www.netnanny.com/netnanny)

a search engine that monitors, screens, and blocks data is it is being used by any application on the computer. Uses a dictionary of user-definable works and phrases deemed inappropriate. Creates an audit trail that may be used by parents to block access to specific sites.

SurfWatch (http://www.surfwatch.com)

Uses a Blocking-Database of sites to restrict access to Web, FTP sites, gopher sites, and chat lines. Does not have monitoring or reporting capabilities. Database is not editable as a protection against precocious children.
