Re: EXT :Re: CD Burner Auditing
Steve,
The main challenge for this solution is the definition of all audit
events that imply removable media has been attached. Juraj's example of
monitoring for mount system calls covers the edge case of copying
to/from mounted devices (given you also identify removable devices
mounted as opposed to say network mounts), but it would not cover the
edge case of say dd'ing to a raw umounted device.

I have not reviewed the patch. I don't know if it still compiles or needs
changes. I am very interested in the topic of being able to load more rules to
watch something closer when certain things occur. If you look at the pdf, one
of the use cases it assists in is auditing files on removable media.
I would like to hear feedback on this patch to see what others think.
