Configure RHEL 6 to be DISA STIG compliant. CAT I findings will be corrected by default. CAT II and CAT III findings can be corrected by setting the appropriate variable to enable those tasks.

Not all findings can be remediated automatically, or they require more complex automation specific to your environment in order to be remediated appropriately. See tasks/not_automated.yml for these findings.

This role will make changes to the system that could break things. This is not an auditing tool but rather a remediation tool to be used after an audit has been conducted, though auditing functionality is in the works.

To install this role with ansible-galaxy use the following command:

ansible-galaxy install -p roles nousdefions.STIG-RHEL6,devel

Based on Red Hat Enterprise Linux 6 STIG Version 1 Release 6 - 2015-01-23.

You should have a general understanding of the nature of the changes this role will make to the system. See the DISA IASE site for details[1].

There are many role variables defined in defaults/main.yml. Here are the most important ones. Feel free to look through defaults/main.yml to see what other configuration options are available.

None.

Correct CAT I and CAT II findings but don't apply all updates.

  become: yes

  vars:
    rhel6stig_update_all_packages: no

  roles:
    - { role: nousdefions.STIG-RHEL6,
        rhel6stig_cat1: yes,
        rhel6stig_cat2: yes,
        rhel6stig_cat3: no
      }

Prompt for the GRUB password.

Each task is tagged with its category, severity, whether or not it is a patch or audit task, and the finding ID, e.g., V-38462. In addition to these four basic tags that all tasks have, there are human-friendly tags such as "ssh" or "dod_logon_banner".

A number of prilimary tasks that do things such as enumerate services on the system and check for the existence of various file will always run unless explicitly skipped by using --skip tags prelim_tasks.

Some examples of using tags:

# Only remediate ssh
ansible-playbook site.yml --tags ssh

# Don't change SNMP or postfix
ansible-playbook site.yml --skip-tags postfix,mail,snmp
