Programs such as the Tiny VPN, Hamachi, PacketiX VPN, and
HTTP Tunnel nowadays pose a potential threat to the network
security when they are deployed on a secured network
segment. These programs utilize the tunneling
technologies, where the data transfers in and out of the
network are encrypted. This network behavior could place
possible security issues where malicious users can cause
information theft since the transferring processes cannot be
monitored due to encryptions. Especially the Hamachi program,
it is a combination of the tunneling and P2P technologies;
Hamachi bypass the access control of VLAN or different subnet
to allow user setup a peer-to-peer communications in the
private network. Program like these may pose a great
danger to a secured, corporate networking environment.
