of the kernel modules that need to be disabled have inconsistent
guidance and tests. The guidance says to add a file in /etc/modprobe.d/ with the content:
"install <module> /bin/true"
However, the actual check in the scan tests for:
"install <module> /bin/false"
This is a list of the ones I found:
$ cd scap-security-guide/RHEL6/dist/content
$ grep -h install * | grep -E
"rds|ticp|usb-storage|cramfs|freevsfs|jffs2|hfs|hfsplus|squashfs|udf|dccp|sctp"
| grep -E "true|false"

Either /bin/true or /bin/false should work to disable the modules.
Setting our files to /bin/false causes the scans to pass right
now.
There was a patch to clean this up a few weeks ago:

I updated the macro which was generating the XCCDF content, pull the
latest and you'll see it.
