Hello Shawn,
Thanks for these two links but to be honest I'm a little bit confused about the
available informations.
That's why I have several questions in order to improve my understanding:
- On the srgmap table, does the "rules mapped" column refer to the
OpenSCAP profile ?
- On the srgmap table, are all the SRG rules from the DISA listed even
the one without a matching test ? Actually, as I told on my first mail, I try
to have a status about the DISA STIG rules who are covered by OpenSCAP profile
and above all the rules who are not covered.
Referring to my last question, I have another question : I thought that in
stead of considering the general SRG rules, it should be more relevant
considering the derivated RHEL-07-XXXXXX which are product specific rules. I
found this table on the output directory :
http://people.redhat.com/swells/scap-security-guide/RHEL/7/output/table-rhel7-stig-manual.html.
Could it be relevant to put the OpenSCAP test in front of each RHEL-07-XXXXXX
in order to have a coverage rate against the DISA product specific rules ?.
I thought that mapping was done with the stig_auxiliary file but actually the
RHEL rules specified into that XML files are for RHEL6 and not for RHEL7. Is it
normal that there are RHEL-06-XXXXX rules on that file for the RHEL7 input ? It
seems a little bit strange for me.
I also looked the disa-os-srg-v1r1.xml file but the rule are not named like on
the last file provided on the DISA site : rules are in the format V-XXXXXX in
stead of RHEL-07-XXXXXX. Is it normal ?
Thanks for your answers
Regards,
Olivier Bonhomme
