Applications used for nonlocal maintenance sessions must implement cryptographic mechanisms to protect the integrity of nonlocal maintenance and diagnostic communications.

Description
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. If unsecured protocols (lacking cryptographic mechanisms) are used for sessions, the contents of those sessions will be susceptible to manipulation, potentially allowing alteration and hijacking of maintenance sessions.

Determine if the HP FlexFabric Switch implements cryptographic mechanisms to protect the integrity of nonlocal maintenance and diagnostic communications.

[HP]display ssh server status

SSH server: Enable
SSH version : 2.0
SSH authentication-timeout : 60 second(s)
SSH server key generating interval : 0 hour(s)
SSH authentication retries : 3 time(s)

Configure the HP FlexFabric Switch to implement cryptographic mechanisms to protect the integrity of nonlocal maintenance and diagnostic communications. Generate local RSA key pairs on the SSH server: [HP] public-key local create rsa Enable the SSH server function: [HP] ssh server enable Enable the SFTP server function: [HP] sftp server enable Configure the user interfaces for SSH clients: [HP] user-interface vty 0 63 [HP-ui-vty0-63] authentication-mode scheme Configure a local device management user, assign password and enable service-type SSH: [HP] local-user admin [HP-luser-admin] password simple xxxxxxxx [HP-luser-admin] service-type ssh

Fix Text (F-72335r1_fix)

Configure the HP FlexFabric Switch to implement cryptographic mechanisms to protect the integrity of nonlocal maintenance and diagnostic communications.

Generate local RSA key pairs on the SSH server:
[HP] public-key local create rsa Enable the SSH server function:

[HP] ssh server enable
Enable the SFTP server function:
[HP] sftp server enable

Configure the user interfaces for SSH clients:

[HP] user-interface vty 0 63
[HP-ui-vty0-63] authentication-mode scheme

Configure a local device management user, assign password and enable service-type SSH:

[HP] local-user admin
[HP-luser-admin] password simple xxxxxxxx
[HP-luser-admin] service-type ssh
