Accepted Answer

Enter an access list and apply it to the virtual terminal interfaces using the access-class command.

Accepted Answer

We can not physically secure a virtual interface because it is virtual.
To apply an access list to a virtual terminal interface we must use the access-class command.
The most simple way to secure the virtual terminal interface is to configure a username & password to prevent unauthorized login.
