Step 1 Connect to the security appliance console port according to the "Accessing the Command-Line Interface" section on page 2-4. To recover passwords, perform the following steps: When the security appliance reloads, you can use the new password to access privileged mode.Performing Password Recovery for the ASA 5500 Series Adaptive Security Appliance Rescue? and / o yesĬryptochecksum: e87f1433 54896e6b 4e21d072 d71a9cbfĢ149 bytes copied 1.480 seconds (2149 bytes / sec) Continue to reload? Reinstall the safety equipment: asa # config reload system has been modified. Save the current configuration with the copy run start command to the above changes permanent: asa # when copying start Source filename ġ5. to view the following commands in the configuration register setting: ASA (config) #exit asa # show versionġ3 at the bottom of the output of the show version command, you should see the following statement: configuration register 0x41 (will be 0x1 next reload)ġ4. While still in configuration mode, reset the default configuration register 0x01 to force a safety device to read the startup boot configuration: ASA (config) # config -register 0x01ġ2. Next, enter configuration mode, enter the following command to change the privileged mode password to a known value (in this case, we & # 39 ll use the password system): ASA # conf t asa (config) #enable password systemġ1. The previously saved configuration is now in the running configuration, but because the safety device has been privileged mode, privileged access is not restricted. Copy the startup configuration file to the running configuration with the following command: copy startup-ciscoasa # config running-config Destination filename ?ġ0. When prompted for a password, press (at this point, and the password is blank): ciscoasa> enable password: ciscoasa #ĩ. Enter the enable command to enter privileged mode. When it finishes booting, you should see a generic User Mode prompt: ciscoasa>Ĩ. Note that the safety devices are ignored in the startup configuration during the boot process. Return the unit the boot command: rommon # 2> bootħ. you need to change the configuration register to 0x41, which tells the machine to ignore the saved (startup) configuration startup: rommon # 1> 0x41 confregĦ. The safety device asks if you want to make changes in the configuration register. The current configuration register is the default of 0x01 (this is actually shown 0x00000001 ). The rommon confreg issue the command to view the current configuration register setting: rommon # 0> confregĤ. Immediately see rommon prompt (rommon # 0>).ģ. When prompted, press Esc to boot process and enter ROM monitor mode. Power-cycle security device by removing and re-inserting the power plug from the outlet.Ģ. They are not suitable for Cisco PIX Firewall appliance.ġ. The following steps were designed with a Cisco ASA 5505 Security Appliance. If you & # 39 the configuration mode, you can load the saved configuration flash memory, your passwords to a known value, change the configuration register to say that the device will load the saved configuration start and charge the device again.Ĭaution: As with all configuration procedures, these procedures have to be tested in the laboratory before use in production environments to ensure suitability for the position. Since the unit ignores the saved configuration on boot, you are able to access the configuration mode without a password. Then the boot process and change the value of the configuration register to prevent the device from reading the configuration stored in the trunk. Will Power cycle the unit from the mains, the power strip and plug it in again. This procedure requires physical access to the device. Instead, you will have access through the console port of the device and the password (s) known values. Today, those passwords are encrypted, and in fact are not recoverable. The term is most commonly used in the procedure "password recovery", which is left over from the days when you could actually see passwords in plain text configuration files. In this article, I & # 39 ll explain how to perform a password "reset" on the Cisco ASA security appliance.
