Fix rule ubtu 20 010066

[yunimoo]

Description:

• Fix UBTU-20-010066
• Add Ansible remediation for ubuntu
• Fix OVAL Definition to regex check for a semicolon ; (smartcard_configure_crl)

Original PR: https://github.com/ComplianceAsCode/content/pull/11078

Rationale:

• Part of Ubuntu 20.04 DISA STIG v1r12 profile upgrade

Review Hints:

Build the product:

./build_product ubuntu2004

To test these changes with Ansible:

ansible-playbook build/ansible/ubuntu2004-playbook-stig.yml --tags "DISA-STIG-UBTU-20-010066

To test changes with bash, run the remediation section: xccdf_org.ssgproject.content_rule_install_smartcard_packages and xccdf_org.ssgproject.content_rule_smartcard_configure_crl. The install_smartcard_packages is required so that tasks in smartcard_configure_crl can run.

Checkout Manual STIG OVAL definitions, and use software like DISA STIG Viewer to view definitions.

git checkout yunimoo:update-manual-stig-ubtu-20-v1r12

This STIG can be tested with the latest Ubuntu 2004 Benchmark SCAP. For reference, please review the latest artifacts: https://public.cyber.mil/stigs/downloads/

Hi @yunimoo. 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.

Could you take a look at the failed tests, specially the Automatus Ubuntu 22.04

I think this one might be related to the fact that conditional fails if package is not properly installed beforehand, leading to that notapplicable error? So the fix might be adding in the template for ensuring that package is installed.

the package needed is part of the tests dependencies: # packages = libpam-pkcs11

@Mab879 do you have any insights on why it seems that the needed package is not getting installed? Is it a bug in ubuntu's automatus?

debconf: delaying package configuration, since apt-utils is not installed

the last line looks suspicious to me

debconf: delaying package configuration, since apt-utils is not installed

that's not really an issue: https://stackoverflow.com/questions/51023312/docker-having-issues-installing-apt-utils

and installing apt-utils will cause other problems

Thank you for the helpful conversations on this. Seems like the packages are installing properly but I am curious, would the test fail / not be applicable if a command is invalid? (i.e., https://github.com/ComplianceAsCode/content/blob/master/linux_os/guide/system/accounts/accounts-physical/screen_locking/smart_card_login/smartcard_configure_crl/tests/commented.fail.sh#L6)

The cp /usr/share/doc/libpam-pkcs11/examples/pam_pkcs11.conf.example does not exist in the container so I assume that this would fail.

I have also tried a simpler test:

#!/bin/bash
# platform = multi_platform_ubuntu
# packages = libpam-pkcs11

mkdir -p /etc/pam_pkcs11
echo "cert_policy = ca,signature,ocsp_on,crl_auto;" > /etc/pam_pkcs11/pam_pkcs11.conf

Which also results in a failure / not applicable when it should pass given the OVALs. Any thoughts on this?

The packages (Dependencies) do not seem to be the problem. I was able to fix the environment setup and will add in a temporary WIP commit for the tests. I'm noticing that the environment sets up properly but openscap is still showing up as notapplicable when:

• Verified that libpam-pkcs11 package is installed
• Path to /etc/pam_pkcs11/pam_pkcs11.conf exists

Errors also seem to persist on master branch... I have also tried testing out the extended criteria install_smartcard_packages which results in notapplicable. So perhaps these errors may be related together in some way?
