A number 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.
