Hey,
I'm hoping someone on this list can point me in the direction of what I'm doing wrong..
We would like to add some custom checks specific to our environment to the scap-security-guide content.
Since this is the first time I've tried to write any OVAL or XCCDF content, I thought I'd start with a nice simple package installed check for RHEL 6 (vmware-tools-core) as a method of learning more about how it all hangs together.
So I created an OVAL file based on some of the other package installed ones:
$ cat RHEL/6/input/oval/package_vmware-tools-core_installed.xml
<def-group>
<definition class="compliance" id="package_vmware-tools-core_installed"
version="1">
<metadata>
<title>Package vmware-tools-core Installed</title>
<affected family="unix">
<platform>Red Hat Enterprise Linux 6</platform>
</affected>
<description>The RPM package vmware-tools-core should be installed.</description>
</metadata>
<criteria>
<criterion comment="package vmware-tools-core is installed"
test_ref="test_package_vmware-tools-core_installed" />
</criteria>
</definition>
<linux:rpminfo_test check="all" check_existence="all_exist"
id="test_package_vmware-tools-core_installed" version="1"
comment="package vmware-tools-core is installed">
<linux:object object_ref="obj_package_vmware-tools-core_installed" />
</linux:rpminfo_test>
<linux:rpminfo_object id="obj_package_vmware-tools-core_installed" version="1">
<linux:name>vmware-tools-core</linux:name>
</linux:rpminfo_object>
</def-group>
And created a group / rule for it in xccdf:
$ cat RHEL/6/input/xccdf/system/test.xml
<Group id="test">
<title>Test Checks</title>
<description>Test Checks stuff..
and stuff...</description>
<Rule id="package_vmware-tools-core_installed" severity="medium">
<title>VMWare Tools must be installed</title>
<description>
VMWare Tools must be installed on all VMware based VM's.
<yum-macro install="true" package="vmware-tools-core"/>
</description>
<ocil clause="the package is not installed" >
<package-check-macro package="vmware-tools-core" />
<br /><br />
If the system isn't a VMWare Based VM, this isn't applicable.
</ocil>
<rationale>Required package for operational support.</rationale>
<oval id="package_vmware-tools-core_installed" />
</Rule>
</Group>
Added a line into the common profile (RHEL/6/input/profiles/common.xml:
<select idref="package_vmware-tools-core_installed" selected="true" />
And finally, an entry in the RHEL/6/input/guide.xslt
<xsl:template match="Group[@id='test']">
<xsl:copy>
<xsl:copy-of select="@*|node()" />
<xsl:apply-templates select="document('xccdf/services/test.xml')" />
</xsl:copy>
</xsl:template>
However, attempting to make just the RHEL6 content fails:

Is anyone able to point me in the direction of what I've missed ?
Kind regards,
