Rules of Use: Campus Data Communication Network
The Campus Data Communication Network (CDCN) is UNM's campus-wide network which connects over 18,000 computers and printers, and other network devices. The campus data communication infrastructure is large and complex. The CDCN supports mission critical functions such as patient care, payroll, academic classes, Internet access, electronic mail, etc.
The CDCN's Rules of Use are intended to maximize the availability of these services. The scope and complexity of the CDCN demands more than centralized management and monitoring. It is necessary that local IT service administrators and end-users recognize the intended use of the CDCN and act accordingly.
It is necessary for users of the CDCN to understand their responsibilities in order to maintain the integrity of the CDCN. The following Rules of Use are intended to maximize the availability of this service and define the end-users' responsibility when using the CDCN.
- Respect the integrity of the network system and comply with the intended use of the network. UNM Action: The concept of the CDCN is to provide easy and universal access in support of the educational mission of UNM. The CDCN is UNM's main network system, although it is not the only network at UNM. There are times when one of these other networks or servers is misconfigured and results in a lack of service for the majority of users on the CDCN. The network or server will be disconnected from the CDCN, and the network administer notified. The problem must be resolved before the network connection is reinstated.
- There will be no commercial network use on the CDCN. UNM Action: UNM receives educational discounts on hardware, software and maintenance from vendors. Due to UNM's non-profit status, UNM may not compete with local businesses to provide equipment or services. Businesses who use .com or .org may not be connected to the CDCN, nor may their DNS registration point to UNM resources. If this occurs, the business will be disconnected from the CDCN by IT.
- Exercise great care to ensure that programs or utilities do not interfere with other computer users. Do not violate the privacy of others. UNM Action: Network users are responsible for all traffic originating from their network device. In addition, network traffic is considered private, thus, any attempts to read or monitor network information of others ("sniffing") is a violation of the privacy act. Repeat violations will result in IT disconnecting the device from the network.
- Rule of Use: Use only assigned addresses. UNM Action: IT is responsible for the assignment of TCP/IP, IPX, and AppleTalk network and subnet/zone addresses and the assignment of any TCP/IP node addresses within these networks and subnets. The impact of making up an IP number or subnet can cause severe campus networking problems. Immediate action will be taken by IT to disconnect a user containing an illegal address from the CDCN.
- Rule of Use: Network users may not infiltrate, damage or modify the network system. UNM Action: UNM employs the Good Neighbor Guideline. If a problem impacts other campus departments and/or buildings, IT is obligated to disconnect the offending device at the most appropriate level. IT will endeavor to select the least intrusive level, whether that is a particular node, building floor, building or Fiber Zone. IT will make a reasonable attempt to contact the department's network administrator for that machine and require that the problem be resolved before the building's backbone connection is reestablished.
- Rule of Use: Network users may not attempt to defeat or circumvent any network specification. This includes any network link, network plate, wiring, software or hardware components of the network. UNM Action: Attempts by individuals to reconfigure the network infrastructure can result in damage to the infrastructure or severe network problems. Examples of this are extending the network with hubs/switches/repeaters, daisy chaining of wiring and the use of non-standard electronics and wiring. Where damage is found to be caused by an individual, repair costs will be billed accordingly. When a user is encountering problems related to non-adherence to industry and/or UNM network standards by installing their own wiring and/or electronics, the user risks being removed from the CDCN.
- Rule of Use: Connecting separate networks via a computer which acts as a gateway or router, using server software so that the server becomes a router, or utilizing an actual bridge or router is not permitted. UNM Action: IT manages all network traffic on the CDCN. Routers and gateways are difficult to configure properly, and a misconfigured router or gateway sending errant traffic can have an adverse impact on the CDCN, and conceivably extending to the Internet. Users not conforming are in jeopardy of being disconnected from the CDCN.
- Rule of Use: Network users may not attempt to defeat or circumvent any security measure established by IT. UNM Action: UNM's network security is based on the "castle philosophy". Each user is responsible for their own security. Any network device that poses security risks threatens the overall integrity of the CDCN, extending to the Internet, and will be disconnected.
- Rule of Use: IT will provide equipment maintenance at no cost to the client only when access to the Wiring Center is restricted to IT. UNM Actions: The following are the Service Levels for networks when restricted access is granted, when access to the building is provided, and a key to a Wiring Center is provided to IT:
The following are the Service Levels for networks when restricted access is not granted and/or a key to a Wiring Center is not provided to IT:
- 24 hrs/day — 7days/wk For any outage that impact a building's backbone connection (Internet, routers, etc.)
- 8-5 M-F For any outage that impacts a building's internal network (network outlet, switch, repeater hub/concentrator).
- 8-5, M-F Outages that impact a building's backbone connection (internet, routers, etc) or a building's internal network (network outlet, repeater hub/concentrator).
Deviation from these Rules of Use will negate IT's obligation to provide support, both in terms of problem resolution and upgrades to equipment and software, and will result in being disconnected from the CDCN.
