Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Marek Haicman 2016-11-02 12:24:56 UTC 
Description of problem:
When scanning empty filesystem [via oscap-chroot utility], there is 54 rules passing. Even though these rules are usually checking existence of something inappropriate, and thus are successful in not finding it, I would like to make sure these rules does not contain holes.

Version-Release number of selected component (if applicable):
scap-security-guide-0.1.30-3.el7.noarch

How reproducible:
reliably

Steps to Reproduce:
1. mkdir ./empty_dir
2. oscap-chroot ./empty_dir oval eval /usr/share/xml/scap/ssg/content/ssg-rhel7-oval.xml
3. see output

Expected results:

Comment 2 Marek Haicman 2018-03-23 18:59:41 UTC 
As OVAL specification is written, having not applicable results can happen only if every part of oval is not applicable. That, under normal circumstances, won't happen. Thus closing this as won't fix.

Using DataStream is the right way to go - applicability is handled by CPE there.
