We can configure an ASA either from CLI or GUI. Below are some basic  configuration that we need to do when we set up a new ASA.  Most of the commands in ASA are similar to the Cisco routers.

Accessing a brand new ASA

To access a new ASA, you need to connect ASA with a console cable to your Computer.  Once the ASA reboots, it will take you directly to user exec mode as below.

In order to enter into enable mode or privilege exec mode, type the command “enable” , and hit enter when it asks for password as there is no password set by default.

ciscoasa>enable

Password:   <There is no password set, so hit enter>
