INTERNET CONNECTIVITY

All Internet connectivity is 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 is highly controlled and capacity upgraded as usage dictates. The Internet connection utilizes double firewall implementation with a public network (Ethernet backbone) established for services that expose 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 is 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 is permitted to communicate freely. E-mail and DNS services communicate freely in both directions since these applications poses no security threat. A Web server is 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 are not permitted on the internal District network. If schools require an independent web server host, this host will be placed on the public network backbone.
