When upgrading an image, the running OS will generate a signature and compare it with the signature attached to the image. Lastly, firmware images are signed and the signature is attached to the code as it is built. If the CRC fails, the FortiGate unit will encounter an error during the boot process. This integrity check is done through a cyclic redundancy check (CRC). Image integrity is also verified when the FortiGate is booting up. A list of expected checksum values for each build of released code is available on Fortinet’s support portal. The corruption could be caused by errors in transfer or by file modification. A file checksum that does not match the expected value indicates a corrupt file. The integrity of firmware images downloaded from Fortinet’s support portal can be verified using a file checksum.
