What is a firewall?
A firewall is a device used to help secure local networks against unauthorised intrusion by outsiders. The device is typically located at the boundary where an organisation connects to the global Internet but can also be used within an organisation to separate and protect individual segments of a large network domain.
UCL Departmental Firewalls
A Departmental Firewall sits at the boundary of a departmental network to control traffic between that department and the rest of the UCL college network. This provides protection for departmental desktops and servers from threats within UCL; restricts access to departmental services and allows a high level of control for all traffic into and out of the departmental LAN.
Please see the UCL ISD Managed Departmental Firewall Service Definition for an outline of the service provided.
