Consider a company whose operations are housed in two buildings on the same property: one building is headquarters, the other building contains network and computer services. The property is physically protected by a fence around the perimeter. The only entrance to the property is through the fenced perimeter. In addition to the perimeter fence, physical security consists of a guarded front gate. The local networks are split between the Headquarters' LAN and the Network Services' LAN. Internet users connect to the web server through a firewall. Dial-up users get access to a particular server on the Network Services' LAN Firewa LAN Connection Guard Gate Headquarters Network and Computer Services Fences Figure 1 lustration of the Company
