INTERNET CONNECTIVITY
All Internet connectivity will be supplied through the District Office with the District Office being the single point of contact for all schools and organizations within the district. This connection will be highly controlled and capacity (bandwidth) upgraded as usage dictates. The Internet connection will utilize double firewall implementation with a public network (Ethernet backbone) established for services that will be exposed to the Internet such as master E-mail, Domain Name Services (DNS) and a World Wide Web server. All connectivity that is initiated from the Internet to the internal District network will be protected via Access Control Lists (ACLs) on the routers that make up the double firewall architecture. Any connectivity initiated from the District to the Internet will be permitted to communicate freely. E-mail and DNS services will communicate freely in both directions since these applications poses no security threat. A Web server will be located on the public backbone and partitioned to allow any school to install a Web home page on the Internet. Individual Web servers that need total exposure to the Internet will not be permitted on the internal District network. If schools require an independent web server host, this host will be placed on the public network backbone.
