AMLS-NM-000350 - Arista Multilayer Switches used for nonlocal maintenance sessions must implement cryptographic mechanisms to protect the confidentiality of nonlocal maintenance and diagnostic communications - telnet
This requires the use of secure protocols instead of their unsecured counterparts, such as SSH instead of telnet, SCP instead of FTP, and HTTPS instead of HTTP.
Configure the network device to use secure protocols instead of their unsecured counterparts. Configuration Example: Disable unsecure protocols. configure management telnet shutdown exit management api http-commands no protocol http protocol https exit Other protocols (FTP) can be denied using AAA and RBAC. For connections that require use of these maintenance protocols, creation of SSH tunnels can fulfill this security requirement. This is summarized here and available at length in the Common Criteria guidance document. Configuration Example: management ssh tunnel NEW local port 514 ssh-server syslogServer user authuser port 22 remote host localhost port 514 no shutdown
