IST

Computer and network services at IST are commonly known as DSI (Direção de Serviços de Informática).

DSI manages the network infrastructure of IST, as well as the main information systems of IST. Since IST is also the central node for the network of the Technical University of Lisbon (Universidade Técnica de Lisboa, UTL), DSI is also in charge of the main backbone services of UTL, including central firewall services, host of central UTL information servers and the interconnection link with the Portuguese Research Network backbone.c
