A firewall is a filter for network traffic, being either network (hardware) or host (operating system) based. Depending on which types of traffic it allows or blocks, a firewall can reduce the risk of unwanted network intrusions ("hacking") as well as limit the spread of viruses and other computer security compromises.
University IT maintains network firewalls for two distinct clients: University (academic and administrative departments) and Residential (student residences).
- Ports on a shared firewall and all associated network switches
- Consulting services for firewall topology and design
- Implementation of the firewall, firewall rules, documentation pages, etc.
- On-going firewall and associated switch maintenance and support
- Monitoring of the health of the firewall
- Each firewall environment has an accompanying firewall documentation page with up-to-date firewall policy and relevant network information.
- Firewall documentation page access is restricted through the use of workgroups and the relevant workgroup is listed on the documentation page. If you need access to your firewall documentation page, please follow up with the appropriate Application Owners (usually your LNA and/or the first person listed as the rule approver when you submit a rule request).
- While anyone with a SUNet ID can submit a firewall rule request, only the designated Application Owner or Rule Approver can approve requests submitted for a firewall project.
- If you need to initiate a new firewall project, please submit a Help request.
- For additional inquiries regarding the University or Residential firewall services, please contact the Firewall Team
