Border Firewall

Implements: CSU Policy ICSUAM 8045 Information Technology Security

Standard: CSU 8045.S301 Boundary Protection and Isolation


firewall is a hardware or software network security device that sits at the juncture between two networks to control what information is allowed to pass between those networks. Usually, the two networks are an organization's internal network and the Internet. A firewall's primary role in information security is to protect computers on the internal network from intentional attacks. Internal network firewalls consist of internal computers and systems, and may be firewalled internally based on risk. The campus firewall is configured for closed border protection. Traffic is blocked to the campus unless a firewall “exception” is enabled. A PDF version of the firewall overview, along with graphic representations, can be found here.

Firewall exceptions must be requested through Omni. Click here to log in to Omni and request a firewall exception on the Firewall tab.

Network Firewall Best Practices


Servers and web applications with firewall requests should be located in a “DMZ” network. DMZ networks provide an additional layer of protection between the server and the campus.
