Comparison of Similarity in the Fix Text Field of the Checklists....

Posted similarity analysis above between RHEL 9 and Amazon Linux 2023, as a lot of the STIGs are the same, just written slightly differently. I think it is all Fedora based, would be nice if all the common ones were 100% similarity, but not the case when things are hand jammed. |

If you wanted to do the same analysis. Replace "rhel9" and "amazonlinux" with DISA STIG checklists converted to CSV. |

I took that same approach to generate this.... I might be able to help more if guided in the right direction.... But, i copied in the highest similarity to RHEL 9 and created placeholders with "pending" status for where similarities do not exist. |

I got the profile to build. I think I just need to go through each item to verify it is 100% correct. If this is not something desired here, I can create a fork, or just make a playbook for my own use. Just let me know how to proceed. @Mab879 |

@Mab879 @nessadc @ngearhart I started a PR here The profile runs, down to 12 rules coming back as N/A - still need to go through each check and make sure its doing the right thing |

@Mab879 @nessadc @ngearhart @bordencastle I had to make a new PR since it was failing for having a merge request in commit... anyways I could use a hand in reviewing the rules, to test this is somewhat difficult, since AL2023 doesn't have the latest oscap, it needs to be built from source on the remote machine, and then use oscap-ssh to scan/remediate. i was able to get it to ~80%ish green 
Steps to reproducePre-req
On the remote AL2023 VM
On local fedora box

rsyslog is not installed, authselect is not installed, /boot/efi is vfat which there is a filter in the rule to exclude vfat from applying nosuid, so that one will never work. I did something to fix the authselect install, and rsyslog, but my code doesn't look great yet. Some rules try to apply, but the rules are missing platform filters for al2023. The common theme I see is that things like rsyslog and authselect might just be assumed to exist, when they should verify the rpms are installed prior to attempting to create configs for them, and certainly the platform labels need to be updated to include al2023. --- Starting Remediation ---

It appears these parts need to be redone after you enable FIPS on the server you are running remediations on as well.... Build oscap from source |

Rename the extension back to .cklb to see in STIG viewer. As a systems administrator, I would be redoing the audit rules if not exact, as they would get flagged by scanning tools, but I'm not sure what the overall theory is with openscap and using the shared rules/templates. The remaining things are around those audit rules not being exact, some rsyslog config, authselect/pam settings. I added in some of the comments "key: line-duplicated", where it is not necessarily a finding, but it would be better if the addition of the setting uncommented and used the existing line instead of creating a duplicate line. As far as audit rules in general, I know for RHEL 9 that part of the ansible playbook ran for 45 minutes. I think it would be more ideal to have OS specific applications for the rules where it's not doing all this querying of shared audit rules. If you did that the playbooks could run in 2-3 minutes to configure audit rules, or you could have something like 1 jinja template to do them all, or 1 per OS where it isn't going through 100's of ansible tasks to provision a few files on any given OS. |

@bordencastle I worked on this a bit before I realized you had put a PR in, I attempted to merge ours together here Something may have gone wrong while merging ours together as the number of rules that are applicable went down slightly. With my latest changes merged into the current PR its looking pretty good with 158 not a finding, 16 NR's and 7 Opens. I believe my changes have fixed the issues you were running into with the audit rules not being applied. As for how long it takes to run the ansible version of the fixes, I use the bash typically it is only taking ~5 minutes for a scan+remediate, will keep working when i get a chance |
