Maura,<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

went wrong. If it's an exact copy of the text from the

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
