It'd be omgz easier to `cp /usr/share/doc/audit-*/stig.rules /etc/audit.rules`, and that likely is the right choice during an initial provisioning process. But then SysAdmins tailor audit rules, the system evolves, and we need to evaluate the audit.rules file against specific auditing guidance items after the pristine audit.rules template is manipulated.On 10/3/13 3:11 PM, fcaviggi@redhat.com wrote:
All,
As a starting point for writing remediation fixes in the SSG - so, I did the following:
$ ls ~/scap-security-guide/RHEL6/input/checks/*.xml | awk '{ print $1 }' | sed s/\.[^\.]*$// > ~/checks
$ ls ~/scap-security-guide/RHEL6/input/fixes/*.sh | awk '{ print $1 }' | sed s/\.[^\.]*$// > ~/fixes
$ sdiff ~/fixes ~/checks | less
There's fair a bit of work to be done for the fix remediations...
Since I'm new to the project, I was wondering if there was any ideas or standards to how the SSG should distribute some of these fixes - for example - a wholesale replacement of the audit.rules and auditd.conf might be preferable than doing piecemeal sed's.
So, if a single rule must be remediated, we can't blow away the whole audit.rules file. Super fun sed scripts it is =/A prevailing thought has been to address backups once the remediations are finished, as we'll have a better handle for which files will need addressing.
I also think the first script that needs to be run is to tar the current existing configurations (as a backup) before applying any fix just in case we do something that jacks the users modifications to the system.
Forcing the backup (through XCCDF/OVAL) is tricky. One thought has been to create an OVAL check -- which is listed first in the profile -- which will *always* fail. The remediation for said OVAL would be to perform the backups. Anyone have a better idea? =/These are really good questions. Thanks for starting the conversation!
Anyway, just trying to get an idea of how to proceed set some goals for my contributions.
