CHAPTER 3

Securing Administration

Secure switch management is needed for environments that perform significant management functions across the Internet. Common functions for secured management are described in the following sections:

￿“Secure Shell and Secure Copy” on page 55

￿“End User Access Control” on page 62

Note – SNMP read and write functions are enabled by default. For best security practices, if SNMP is not needed for your network, it is recommended that you disable these functions prior to connecting the switch to the network (see “Using Simple Network Management Protocol” on page 35).

Secure Shell and Secure Copy

Because using Telnet does not provide a secure connection for managing a G8124, Secure Shell (SSH) and Secure Copy (SCP) features have been included for G8124 management. SSH and SCP use secure tunnels to encrypt and secure messages between a remote administrator and the switch.

SSH is a protocol that enables remote administrators to log securely into the G8124 over a network to execute management commands.

SCP is typically used to copy files securely from one machine to another. SCP uses SSH for encryption of data on the network. On a G8124, SCP is used to download and upload the switch configuration via secure channels.
