Secure Access

Maintaining secure access to our systems is of the utmost importance to the Computing and Communications Center (CCC). For this reason, there is a new, more restrictive policy for computer usage and access.

Server Information

SSH (Secure SHell)

SSH (Secure SHell) is a program to log into another computer over a network, to execute commands on a remote machine, and to move files from one machine to another. It provides strong authentication and secure communications over insecure channels. SSH clients encrypt passwords and provide a higher level of security than telnet connections. The most noticeable difference when using SSH is that the client prompts for the password prior to making the connection. This enables the client to encrypt the password before passing it over the network to the target system.

The Helpdesk currently supports the following clients:

SCP (Secure CoPy)

SCP is a secure replacement for the more common FTP (File Transfer Protocol) application. SCP (Secure CoPy) is a protocol for transferring files to or from a remote host. It uses SSH as the low-level communications protocol and therefore benefits from the security present in SSH. Unlike previous FTP connections, all SCP connections should now be made to the server:

The Helpdesk currently supports the following client:

ISPs (Internet Service Providers)

Internet Service Providers allow users to gain access to the Internet and various Internet resources from their home using either existing phone or cable technology in the home.

Most cable companies provide Internet access options to their customers through the use of a cable modem which connects directly into a standard network card and uses new or existing cable lines to provide high-bandwidth (high-speed) access to the Internet.

Likewise, many telephone companies offer DSL (Digital Subscriber Line) options to their customers. DSL uses your existing phone line to provide high-bandwidth (high-speed) access to the Internet.

Helpdesk has compiled a listing of local Internet Service Providers for your convenience. To find an Internet Service Provider in your area, try using the Find An ISP web site. When using an ISP from off-campus, use of the WPI Virtual Private Network (VPN) client is recommended. The VPN provides off-campus users with secure encrypted access to WPI's Extranet, allowing users to access most campus networking resources while off-campus.
