Some services are only available through the university network. These include, for example, access to network drives and the download of online resources from the homepage of the University Library. If you want to access these services when you are not at the university, you need a VPN connection. A '''V'''irtual '''P'''rivate '''N'''etwork guarantees secure access to the university network through other networks.
