FIPS cipher mode for AWS, Azure, OCI, and GCP FortiGate-VMs

AWS, Azure, OCI, and GCP FortiGate-VMs support FIPS cipher mode. You must remove all VPN configurations before you can enable FIPS CC mode.

FIPS cipher mode only allows a restricted set of ciphers for features that require encryption, such as SSH, IPsec and SSL VPN, and HTTPS. You cannot use insecure protocols such as Telnet, TFTP, and HTTP to access the FortiGate-VM.

You must perform a factory reset to disable fips-ciphers mode.

To enable fips-cipher mode:
config system fips-cc
    set status fips-ciphers
end
Warning: entering fips-ciphers mode. To exit this mode, factory reset is required.
Do you want to continue? (y/n) y

The following behavior occurs when you enable FIPS cipher mode:

  • You can restore a license, image, configuration, and so on from an FTP server.

  • The following options are available:

    • aes128-gcm@openssh.com
