ASA -----User with low privilege

[mohamed.fawzy2012]

Dears ,

i want to know which privilege i suppose to use to allow certain user to do "sh version" command as i tried some privilege and they all do the same 

as privilege 15

I don't think you can restrict access to only "show version" but you cannot restrict access to "show" commands only on an ASA with local database for AAA.

Assign the user a non-default privilege level say level 10. Then customize the "show version" commmand to be available to a user with less than full enable (level 15) privilege.

Hello!

You can use for example  command 

privilege exec level 14 show version

The ASA capabilities are a bit different than IOS. On an ASA, here would be the command:

asa-5512(config)# privilege cmd level 14 mode exec command show ?

configure mode commands/options:
 <cr>
asa-5512(config)# privilege cmd level 14 mode exec command show

Note that you cannot add "version" after show. However as noted in the link I provided earlier, we can use privilege level 0 which includes show version and a few other commands.

We would then add the user thus:

asa-5512(config)# username showuser password showuser123 privilege 0

This new user has access to a limited set of show commands but cannot configure:

[c:\~]$ ssh showuser@x.x.x.x

Connecting to x.x.x.x:22...
Connection established.
To escape to local shell, press 'Ctrl+Alt+]'.
Type help or '?' for a list of available commands.
