You can use audit dispatcher to react to audit events.... When u get a MOUNT event you can see where sr0 is mounted and start a new watch for that path. If you are not writing an ISO I think it has to be mounted.

Hmm. That is an interesting thought, but I would think there is no filesystem that would be able to be mounted until the user has written something to the disc first. In other words I don't believe blank media gets mounted as part of the burning process (at least not in my experience anyways--maybe I'd need to turn some feature on for that?).

One way is to watch for the main folder where /dev/sr0 is mounted. That way everything under that is watched.
If an ISO is burned then we cannot know what is inside that ISO.

An alternative is to watch access to known sensitive files on the machine (whose cd burner you want to watch). and known burning commands. That way you know who is accessing sensitive content. If the same login session generates events for these files and programs they might be burning sensitive files.

Does anyone know if it is possible to audit what filenames users are burning to optical media?

I suppose I can put a watch on the /dev/sr0 device for write events, but this does not give me any idea what was written to the disc. I suppose I could also set an execve watch all burner programs, eg. /usr/bin/k3b /usr/bin/brasero /usr/bin/cdrecord /usr/bin/cdrdao /usr/bin/dvdrecord, to know if someone opened the burning interface; but how could I tell what it was they were writing?

Any suggestions are welcome.
