What is a firewall?

A firewall acts as a security system, helping to prevent unauthorized access to computers or network resources.  A firewall follows a set of rules to filter the information entering and exiting a network, or computer, allowing or denying access to each specific request.

 

Why are firewalls used?

Firewalls insure that your valuable information is protected by inspecting  the information passing into and out of the network, filtering it based on a specific set of rules. These rules tell the firewall whether to permit or deny access to the network or computer, keeping out unauthorized users who may want to gain access to the information stored behind the firewall.

How do I request to add or change a rule?

If you are responsible for a computer on the Universities network that provides Internet services like a web server, FTP server, or file server to an off-campus computer, please let us know so we can configure the firewall to accommodate these services.

To request a change, please contact the IT Service Desk and have the following information available about the static mapping request; the name of the system that needs an exception set, the IP address, and any specific ports you need open for this system. We would also ask that you remember to let us know when you no longer need this exception implemented so we disable it accordingly.

Are there any other options instead of a rule change?

YES! If you are using the VPN service, you can access University systems from off-campus without need for firewall exceptions. VPN is the preferred solution for remote access. For additional help, contact the IT Service Desk by phone at 304-696-3200 or by email at itservicedesk@marshall.edu
