Hmmm, I'll look into the umask thing, but I was under the
assumption that if one failed, the whole file should fail, so
that's probably the reasoning behind never looking for a second
umask value. Note that the prose guide section for each umask
setting makes no attempt to distinguish between multiple places to
change umask settings.<br>
<br>
I checked and noticed that admin_space_left and
admin_space_left_action don't show up at all in the STIG. I also
noticed that the title for the prose section describing
admin_space_left_action is wrong in the SSG. I wonder if the
variable name is also wrong and the check is looking for the wrong
thing? I will check this tomorrow.<br>
<br>
I don't know where "ignoresyslogemailexecsuspendsinglehalt" is
coming from. Grepping through the entire SSG reveals nothing. When
I get in tomorrow, I'll try to track down what's happening (maybe
regex gone wrong?).<br>
<br>
If you open up the XCCDF in a text editor, you'll notice that
Rules will sometimes contain <check> tags. These check tags
have nearly unreadable ids, BUT you will find them in
ssg-rhel6-oval.xml with the same names and can get a human
readable ref_id that will point you to the correct file in
RHEL6/input/checks in the git repo.<br>

I just pulled the latest git stuff down and made it all,
zipped up all the 'ssg-' files from the output directory and
dropped that on the SCC3.1 GA scanner. A stock box had 6 passes
and 5 failures out of total of 388 items. After locking it down
with SB I went to 5 passes and 6 failures (yep - wrong way) out
of 388. Operator error on making the packages ?<br>
<br>
Couple of interesting questions on the results (after scan):<br>
<br>
<br>
<br>
Set default bash umask (ditto for csh and default umask)<br>
Examing the indicated files shows there are two places where
the umask could be set, one for 002 and one for 022, with the
UID of the caller determining which is used. The scanner is
catching the first instance.
<br>
<br>
Configure Auditd for space_left and admin_space_left:<br>
In both cases I inspected the /etc/audit/auditd.conf file
and verify that the required line is present according to the
prose. I do notice that the list of appropriate actions appears
to be a single 'word' set to be:<br>
<br>
ignoresyslogemailexecsuspendsinglehalt<br>
<br>
Not sure what is going on under the hood to know if these are
being glommed together for the prose but kept separate for the
OVAL checks or not.<br>
<br>
I need to try and rerun with the SCC rc6 beta, but may not have
time today...<br>

Stupid question, but what are you running against exactly?
The RPM or the latest git checkout? I want to make sure that
if I run this, I'm seeing the same results, and I've made a
lot of changes to OVAL checks in the git repository in the
past few weeks. I'm going to run through your list,
comparing it against the OVAL checks.<br>

Fix text definitely implies this. It's not the only service
that implies it's allowed in certain environments, but then
proceeds to only accept a value of disabled.<br>

Going back to my many many OVAL check updates, I'd like to

it's an exact copy of the text from the STIG, I'll work off
that.<br>

Do you mean it's disabled on your system, but the OVAL

The STIG actually says that stime is not necessary, which is
kind of a strange wording, but the suggested line in the fix
text prose is correct, at least. So far as OVAL checks go, I
haven't gotten to testing audit checks yet. Maybe this is
broken. I'll check it out once I've deciphered the OVAL
check.<br>

These are both automated checks. Unless the package name is
