  14. 172.xxx.xxx.xxx “Us” Internal Network “Boogies” The Internet 204.xxx.xxx.1 The Firewall & IP Addresses

  15. Novell DHCP Server software on a Compaq ML 530 DHCP Service (Dynamic Host Configuration Protocol) * Because of the Firewall, all Internet traffic from SECCNET will have the same IP address (204.xxx.xxx.1). * It is the Firewall’s job to track internal addresses associated with outside traffic. * It is the DHCP Server’s job is to dispense “bogus” IP addresses to the internal nodes on the network.

  16. Internal Protection Why, What, & How

  17. Why do we need Internal Security? SECCNET Currently has: • 9 servers • 650 + Workstations • Administrative software • Financial data • Personnel Information • Etc. • Student records • GroupWise • Full Internet access

  18. SECCNET VLAN’s (Virtual Local Area Networks) SECCNET Internal Network

  19. SECCNET VLAN’s (Virtual Local Area Networks) SECCNET Administrative Network SECCNET Instructional Network Cisco 6509 Switch will allow us to configure these 2 VLAN’s through its Layer 3 switching capabilities.

  20. SECCNET Upgrade: We've Come Full Circle from Where We Started

  21. Last Thoughts • Do the “PR” thing with administration, employees, and students • Provide the technicians with upgrade information • Keep the security parameters loose initially • Once the upgrade is in place, concentrate on understanding your new network • Purchase some kind of network monitoring software
