Description:

  • Modify sshd_use_approved_ciphers_ordered_stig rule to better align with Ubuntu STIG (UBTU-20-010044, UBTU-22-255050)
  • Switch to using sshd_approved_ciphers variable
  • Switch to checking the whole set of algorithms instead of just a subset
  • Extend OVAL check to allow distributed configs
  • Analogous to Align sshd_use_approved_macs_ordered_stig with Ubuntu STIG #11853

Rationale:

  • Checking just for a subset does not meet the requirement of having the algorithms in the exact same order (as specified in the STIG), because it is possible to specify only the last algorithm, which is effectively the same as specifying them in the wrong order

Hi @mpurg. Thanks for your PR.

I'm waiting for a ComplianceAsCode member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

@mpurg
Modify Ubuntu OVAL for sshd_use_approved_ciphers_ordered_stig
da09757 
The OVAL now also allows distributed configs and uses
the variable `sshd_approved_ciphers` instead of hardcoded values.

The implementation is based on the template `sshd_lineinfile`,
modified to allow external variables as values and checking for
FIPS compliant OS.
@mpurg
Modify Ubuntu ansible remediation for sshd_use_approved_ciphers_order…
0918aac 
…ed_stig

The remediation now uses the ansible_sshd_set macro and the
sshd_approved_ciphers variable.
