CUHK VPN (Virtual Private Network)

CUHK VPN (Virtual Private Network)

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.
