Secure Shell (SSH)

SSH is the abbreviation of Secure Shell, which is a program allowing secure remote login and secure network services over

an insecure network. It allows you to securely login to remote host computers, to execute commands safely in a remote

computer and so forth, and to provide secure encrypted and authenticated communications between two non-trusted hosts.

SSH with its array of unmatched security features is an essential tool in today’s network environment. It is a powerful

guardian against the numerous security hazards that nowadays threaten network communications.

ure communication has been established

ections with the Switch using the SSH User Authentication window. There are three

The steps required to use the SSH protocol for secure communication between a remote PC (the SSH Client) and the

Switch (the SSH Server), are as follows:

1. Create a user account with admin-level access using the User Accounts window in the Management

folder. This is identical to creating any other admin-lever User account on the Switch, including specifying a

password. This password is used to login to the Switch, once sec

using the SSH protocol.

2. Configure the user account to use a specified authorization method to identify users that are allowed to

establish SSH conn

choices as to the method SSH will use to authorize the user, and they are Host Based, Password, Public Key,

and None.

3. Configure the encryption algorithm that SSH will use to encrypt and decrypt messages sent between the

SSH Client and the SSH Server, using the SSH A

4. Finally, enable SSH on the Switch using the SSH User Authentication window.

After following the above steps, you can configure an SSH Client on the remote PC and manage the Switch using secure,

in-band communication.
