You should set a password on your Cisco ASA 5505 even if you don’t have remote management set up. If a computer inside your network gets hacked, it could be used to gain access to the firewall.
To set the enable password on your Cisco ASA 5505:
- Get into the command line. I prefer using the console cable to directly connect.
- Hit enter a few times to get the prompt.
- Type ‘ena’
to enter enable mode.
- Type ‘config t’
- Type ‘enable password PaSsWoRd’
, replacing the second, ‘PaSsWoRd’ with desired password.
Now when you enter enabled mode in the console you’ll be prompted for a password. When you log into the ASDM you leave the Username field blank, and type in only your enable password in the Password box.
