I want to verify my kernel. I found this page explaining how to verify .iso files.

However, I don't have a kernel .iso file. I only have image files under boot, e.g.

  • -rw-r--r-- 1 root root 1443719 Aug 9 04:08 abi-4.10.0-32-generic
  • -rw-r--r-- 1 root root 204970 Aug 9 04:08 config-4.10.0-32-generic
  • -rw-r--r-- 1 root root 43032519 Aug 15 01:00 initrd.img-4.10.0-32-generic
  • -rw------- 1 root root 3718993 Aug 9 04:08 System.map-4.10.0-32-generic
  • -rw------- 1 root root 7398816 Aug 9 04:08 vmlinuz-4.10.0-32-generic
  • -rw------- 1 root root 7400728 Aug 10 23:42 vmlinuz-4.10.0-32-generic.efi.signed

Question: Is there a way to verify these files?

Additional information:

  • The kernel version given by uname -a is 4.10.0-32-generic:

    • Linux user-desktop 4.10.0-32-generic #36~16.04.1-Ubuntu SMP Wed Aug 9 09:19:02 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

    • My login screen tells me I am on Ubuntu 16.04.3, differing from the report byuname -a

  • What makes you think you need to verify your kernel? – fosslinux Aug 23 '17 at 2:22
  • @ubashu - My plan is to set up a routine where I periodically verify the system. If it's fast then I can just do it on every login. – Craig Hicks Aug 23 '17 at 8:44
  • So what makes you think you need to verify the system??? – fosslinux Aug 23 '17 at 20:50
  • Overall, security seems like a good idea. However, maybe I'm grabbing the wrong end of the stick? – Craig Hicks Aug 24 '17 at 7:33
