Policy approved by:

UICTC

 

Table of contents

Background

At its meeting on 7 March 2005, the University Information and Communication Technology Committee (UICTC) approved the recommendation that the UCT network is a core ICT service. UICTC said that ICTS:

  • will be responsible for ensuring compliance;
  • is to regulate the installation, management and maintenance of all network devices;
  • has full power to ensure the security of the network and is to set standards of manageability; and
  • will set standards for workgroups and end users to connect to the UCT network.

UICTC further requested that ICTS set up a memorandum of understanding. This was adopted at the UICTC meeting on 8 June 2005.

Purpose

This policy allows access to the above services, while restricting access to other services that are not widely required for academic purposes.


Definitions

1. Types of devices

For the purposes of this document, three types of devices are defined as follows:

Type of device Definition Examples
End-user device Any device intended for use by one individual at a time.
  • Personal computers
  • Laptops
  • Workstations
  • PDAs
  • Mobile phones
Workgroup device Any device configured to be used by more than one end-user for the purposes of sharing files, printers, scanners or other end-user devices.
  • Servers
  • HP JetDirect devices
  • Network-aware scanners, copiers, printers, fax machines
Network infrastructure device Any device intended to construct, extend, support, manage or secure a network.
  • Routers
  • Hubs
  • Switches
  • Bridges
  • Wireless access points
  • Firewalls
  • Gateways
  • Any workgroup or 
    end-user device configured to perform the function of a network infrastructure device including proxy servers, network address translation devices, DHCP servers, remote access servers and DNS servers 
2. UCT network

For the purposes of this document, the UCT network is defined as:

  • The data network that extends across UCT-owned or –leased premises excluding the Graduate School of Business.
  • The network that connects various classes of devices to each other and to third-party networks such as the Internet.
  • Consisting of data cables and network infrastructure devices.
  • From the average end-user’s perspective, this includes the network up to the plug in the wall.

Applicable to

All UCT staff, third parties and students that make use of UCT's network and its available services.


Exceptions

All individuals that do not make use of UCT's network and its available services.


Policy summary

This policy:

  • describes the UCT network.
  • defines the network as an enterprise-wide essential ICT service, that will, in the main, be owned and managed by ICTS.
  • defines special purpose networks and top-up services.
  • lists the next steps generated by the definition of the network as a core service.


Policy details

All student residences will connect to the University network from behind routers that will also act as firewalls. These firewalls will be used to manage traffic to and from student residence networks. The following rule sets have been implemented on the firewalls between the UCT network and student residences:

EXAMPLE:
A department may wish to ensure complete wireless coverage of all its spaces. While ICTS agrees that this is desirable in the long term, the central budget is not sufficient to meet this requirement. Should the department purchase devices without consulting ICTS, the department could inadvertently choose equipment that cannot be integrated with the rest of the infrastructure, cannot be managed effectively in order to maintain service levels, or that poses a security risk to the network.
