Configuring Secure Shell Security

Secure Shell permits network users to securely login to the network from a remote location over an insecure network. SSH a secure login to remote host computers, a safe method of executing commands on a remote end node, and will provide secure encrypted and authenticated communication between two non-trusted hosts. SSH, with its array of unmatched security features is an essential tool in today’s networking environment. It is a powerful guardian against numerous existing security hazards that now threaten network communications.

Ensure the following steps are completed before configuring SSH:

•Create a user account with admin-level access using the User Accounts window in the Administration folder. This is identical to creating any other admin-level User Account on the Switch, including specifying a password. This password is used to logon to the Switch, once a secure communication path has been established using the SSH protocol.

•Configure the User Account to use a specified authorization method to identify users that are allowed to establish SSH connections with the Switch using the Current Accounts window (Security > Secure Shell (SSH) > SSH User Authentication). There is a special SSH method that mey be used to authorize the user: Public Key. The default value is None.
