FIPS Support 9 NOTE If FIPS is enabled, all logins should be done through SSH or direct serial and the transfer protocol should be SCP. Updating the firmwarekey 1. Log in to the switch as admin. 2. Type the firmwareKeyUpdate command and respond to the prompts. The firmwareDownload Command As mentioned previously, the public key file will need to be packaged, installed, and run on your switch before downloading a signed firmware. When firmwareDownload installs a firmware file, it needs to validate the signature of the file. Different scenarios are handled as follows: • If a firmware file does not have a signature, how it is handled depends on the "signed_firmware" parameter on the switch. If it is enabled, firmwareDownload will fail. Otherwise, firmwareDownload will display a warning message and proceed normally. So when downgrading to a non-FIPS compliant firmware, the "signed_firmware" flag needs to be disabled. • If the firmware file has a signature but the validation fails, firmwareDownload will fail. This means the firmware is not from Brocade or its content has been modified. • If the firmware file has a signature and the validation succeeds, firmwareDownload will proceed normally. SAS, DMM, and third party application images are not signed. Configuring the switch for signed firmware 1. Connect to the switch and log in using an account assigned to the admin role. 2. Type the configure command. 3. Respond to the prompts as follows: System Service Default is no; press Enter to select default setting. ssl attributes Default is no; press Enter to select default setting. snmp attributes Default is no; press Enter to select default setting. rpcd attributes Default is no; press Enter to select default setting. cfgload attributes Select Yes. The following questions are displayed: Enforce secure config Upload/Download: Select yes Enforce signed firmware download: Select yes Webtools Default is no; press Enter to select default setting. attributes System Default is no; press Enter to select default setting.
