Before we could be ACK'ed (for commit), it needs some changes, primarily
relating to granularity as noted in
https://fedorahosted.org/scap-security-guide/wiki/newxccdf .
The overall goal is to include the relevant information from the RHEL 5
prose document, but translate it into XCCDF in a way that facilitates
its re-use by different parties (and straightforward automation).
There was also some discussion in
https://fedorahosted.org/pipermail/scap-security-guide/2012-April/000185.html
suggesting one CCE per Rule (as the preferred
level of granularity).
There are some benefits to this:
1)
This will position us (and Mitre) to easily
verify the correspondence/agreement between CCE description and XCCDF
description.
2)
After a set of OVAL checks is run, an
admin (or a C&A person) may only see a list of pass/fail results. When
possible, we want to keep these precise to enable well-informed
decisions. This is also relevant to the eventual addition of <fix>
tags, which may attempt to tie a remediation action to a particular
check's result.
The software also could have changed since RHEL 5, and we should not
assume that there are no errors in the RHEL 5 document to begin with. I
noticed that there is a squid user as the owner (of presumably a
sub-task) of the squid service. In your testing, does the product now
do (out of the box) what the lower_privileges Rule suggests configuring
for RHEL 5 (for the most part)? If so, we can drop that. I'm also
generally a bit more reluctant now to suggest things like altering
system startup scripts; this affects our ability to verify their integrity.
Thanks,
Jeff
