Today, such passwords are encrypted and not actually recoverable. Instead, you will gain access to cisco asa password recovery appliance via the console port and reset the password s to known values. This procedure requires physical access to the device. You will power-cycle your appliance by unplugging it at the power strip and plugging it back in. You will then interrupt the boot process and change the configuration register value to prevent the appliance from reading its stored configuration at boot. Since the device ignores its saved configuration on boot, you are able to access its configuration modes without passwords. Once you're in configuration mode, you will load the saved configuration from flash memory, change the passwords to a known value, change the configuration register value to tell the device to load its saved configuration on boot, and reload the device. Caution: As with all configuration procedures, these procedures should be tested in a laboratory environment prior to usage in a production environment to ensure suitability for your situation. Power-cycle your security appliance by removing and re-inserting the power plug at the power strip. The current configuration register should be the default of 0x01 it will actually display as 0x00000001. The security appliance will ask if you want to make changes to the configuration register.

While still in Configuration Mode, reset the configuration register to the default of 0x01 to force the security appliance to read its startup configuration on boot: asa config config-register 0x01 12. Use the following commands to view the configuration register setting: asa config exit asa cisco asa password recovery version 13. At bottom of the output of the show version command, you should see the following statement: Configuration register is 0x41 will be 0x1 at next reload 14. Reload the security appliance: asa reload System config has been modified. Copyright c 2007 Don R. For more information and to purchase copies of his books, visit soundtraining.
