When working off campus, use MIT's Virtual Private Network (VPN) to securely and reliably access MIT resources. A VPN makes a tunneled network connection through the internet which securely connects you to remote sites. It makes it appear that your computer is on MIT's network. By using a VPN to go from your computer to the resources you are accessing, anyone intercepting the encrypted data can't read it, so it's especially useful when using untrusted wireless (think Starbucks).
MIT's VPN assists MIT clients with encrypted connectivity when on or off campus. The service also provides a way to work through the various port blocks, firewalls, and other obstacles that Internet Service Providers and administrators have put in place to protect the network. If you are unable to access an MIT resource remotely, try VPN. For instance, remote desktop connections will often be blocked from off-campus, but using the VPN will allow you to access them.
To use the service, install the Cisco AnyConnect VPN client on your system.
