Internet Evolution [cont.) During the 1970’s various other networks were connected This led to the 1980’s Internet concept which means each network can seamlessly interconnect with other networks Businesses began using the new Internet with workstations and local area networks The Internet has become a network of networks 3-

Internet Evolution (cont.) In 1989, Tim Berners-Lee of CERN came up with the hypertext concept World-Wide Web is really the application of hypertext documents and other materials Hypertext is conceptually a ‘speed dial’ feature in that a user points to and presses the hypertext link and the system automatically goes to that location 3-

Key Web Terminology Website Hypertext link Web page Home page Universal resource locator (URL) Protocol Domain name Path Browser FTP (File Transfer Protocol) 3-

Internet Security Any resources linked to data communications have risk Security by physically separating the Web site from the firm’s computer resources Security by using passwords that allow access to computing resources ‘Firewalls’ using routers, intermediary computers or application-level methods 3-

An Application-Level Firewall External Services Border Router IP Choke Protocol Filter Internal/External Service Gateway Internal Router Router Isolation Mechanism Internet Connectivity Supplier’s Network Internet Internal Network Incoming packets from the Internet pass through the connectivity supplier’s network to a router and to the organization The packet goes to a router box that duplicates the function of the external router Rather than routing the packet directly to its destination, the router redirects traffic through an external services host and an IP “choke” host The external services host runs desired apps such as E-mail interface The IP choke performs actual protocol filtering Traffic is sent through a gateway to a separate router box on the internal network, configured according to internal security policy 3-

Intranet Internet technology used for internal communications and applications Used for many business applications requiring communication 3-
