CUHK VPN allows CUHK users to securely connect to the campus network even over a non-CUHK network access (e.g. home broadband service). The VPN technology encrypts the data transferred online and prevents private information from wiretap. Some CUHK websites / online resources are accessible off campus only if users have connected to a VPN connection.
Max connection session: 12 hours with 1 hour idle time out except Windows 8 / 8.1, Mac OS X 10.9 or above and iOS 7 or above.
