Network Security

 

Network Security

In DCU a network security policy exists to ensure secure and reliable network access and performance for the University community. Internet access to University resources and University access to Internet resources are both important elements in sustaining the University's primary missions of instruction, research, and public service. This policy is intended to protect the integrity of the University network and to mitigate the risks and losses associated with security threats to the University network and information systems. Please see the Policies section for details.

Firewall Ports

The University's external Internet firewall policy is to deny all external Internet traffic to the University's network unless explicitly permitted. Access and service restrictions may be enforced by IP address and/or port number. Proxy services may be used in conjunction with the firewall to restrict usage to authenticated individuals. This policy is designed to protect University network users from attacks launched from the Internet.

In certain cases an individual may require access to certain services or a software application that uses ports normally blocked by both the firewall and proxy server.

If you have a requirement for certain ports to be opened to allow you to access a service or use a software application please contact the Networks Group by email at the address below stating the service or application you wish to use and the ports you require to be opened.
