Thanks for submitting this PR! Here's some feedback on this draft.

I think each platform should track an independent last-updated field. Just like the guides on the website, sometimes one platform needs an update, but the others don't.

Also, it would be a good idea to track a change log per platform (also like the online guides).

Perhaps the guides can be stored as a dictionary with "last_update", "change_log", and "instructions" fields. That would organize it in a cleaner way in the code, I think.

As an example of what I mean by using a dictionary, see here:

ssh-audit/src/ssh_audit/builtin_policies.py

Line 27 in a01baad

BUILTIN_POLICIES: Dict[str, Dict[str, Union[Optional[str], Optional[List[str]], bool, Dict[str, Any]]]] = {

Perhaps this class could be called HardeningGuides.

If the class constructor accepts an OutputBuffer, then we can print using its good() method to handle colors for us.

Also, in the code, ssh-audit always refers to itself as "ssh-audit" (in lowercase).

Perhaps this option could be called --get-hardening-guide?

Also, the user would want to see what hardening guides are available, so perhaps the supported arguments to --get-hardening-guide can be listed with --list-hardening-guides.

if the argument is called with out any further data ( server / version / edition ) or incorrectly formatted data it will print out the supported configurations.

With that said I have updated the configuration to print an example.

Would this be acceptable ?

python3 ssh-audit.py --get-hardening-guides ssh-audit Version : v3.4.0-dev Guides Last modified : 2024-10-01 Error unknown varient : OS Version Edition For current, community developed and legacy guides check the website : https://www.ssh-audit.com/hardening_guides.html Supported Server Configurations : Amazon 2023 Server Debian Bookworm Server Debian Bullseye Server Rocky 9 Server Ubuntu 2404 Server Ubuntu 2204 Server Ubuntu 2004 Server Supported Client Configurations : Amazon 2023 Client Debian Bookworm Client Mint 22 Client Mint 21 Client Mint 20 Client Rocky 9 Client Ubuntu 2404 Client Ubuntu 2204 Client Ubuntu 2004 Client Example Usage : python3 ssh-audit.py --get-hardening-guides Ubuntu 2404 Server

if the argument is called with out any further data ( server / version / edition ) or incorrectly formatted data it will print out the supported configurations.

Thinking from a user's perspective, usability would be better if we presented an obvious --list-hardening-guides option.

Would this be acceptable ?

Sure, that would work. My only feedback would be that having one last-modified field for all guides wouldn't be helpful to users; each platform should have its own history (date, integer version number, change log message, and hardening instructions).

Perhaps the current -L and -L -v behavior could serve as a model here. Notice how ssh-audit -L only shows the latest version of policies, but ssh-audit -L -v lists previous versions of the policies as well, including their change log messages. It would be nice if --list-hardening-guides did the same thing.

I suppose this class name should be updated to TestHardeningGuides.

Hi Joe,

As always, thanks for the review and feedback.
I'll look into the changes and get back to you.

Again I will try and update and attempt to squash everything, and again if it turns into a mess - I'll close this one of and create a clean PR when the code is a bit closer to a second review.

Cheers.

One way to do it is to make a working branch for your next revision, add as many commits as you'd like to that, then simply make one squash merge commit back into print_guide_v2.

For example:

$ git checkout print_guide_v2  # Start with the branch that corresponds to this PR
$ git checkout -b pr307_revision_2  # Copy this branch, and use it for experimentation
$ git add [...]; git commit [...]  # Make as many commits as you'd like to this pr307_revision_2 branch
$ git checkout print_guide_v2; git merge --squash pr307_revision_2 branch  # Squash all commits from the experimental branch into one commit in print_guide_v2.

Once you push the one squashed commit in print_guide_v2, this PR will be automatically updated with that one commit. Hope this helps!
