15. Security Commands 15 This chapter describes commands for: • Managing the switch using SSH2 • Configuring switch user authentication through a RADIUS client • Configuring switch user authentication through TACACS+ • Protecting the switch from Denial of Service attacks SSH Secure Shell 2 (SSH2) is a feature of the NETGEAR 8800 that allows you to encrypt session data between a network administrator using SSH2 client software and the switch. Configuration and policy files may also be transferred to the switch using the Secure Copy Program 2 (SCP2). SSL Secure Socket Layer (SSL) allows users to connect using a more secure HTTPS connection. Note: If you cannot find SSH or SSL commands, your image probably did not come with SSH or SSL preinstalled. To download and install the SSH/SSL module, go to http://kbserver.netgear.com/products/xcm8806.asp or http://kbserver.netgear.com/products/xcm8810.asp. User Authentication Remote Authentication Dial In User Service (RADIUS, RFC 2138) is a mechanism for authenticating and centrally administrating access to network nodes. The NETGEAR 8800 RADIUS client implementation allows authentication for SSH2, Telnet or console access to the switch. Chapter 15. Security Commands | 554
