I am looking for places to read about protections taken in linux to prevent firewire devices from dumping memory. This is a set up over other physical access attacks because of the potential for grabbing memory contents without having to reboot a machine. (Which could expose things such as keys for encrypted partitions.) I have found some sources describing that firewire devices can use bus mastering to dma various regions of memory and that you can prevent this by not loading firewire modules, but I haven't been able to frame a google search to find discussion about whether protecting against this in the drivers is possible and whether anything has been implented. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
