I notice that if I boot into any linux liveCD, my NTFS drives are automatically mounted, and I have access to everything. This seems like a huge security issue.
Is this a filesystem issue or something else? If I were running Linux on an ext4 drive and set file permissions to 700, could I still access the files so easily?
If not, is there a way to make Windows files secure using permissions?
I don't really want to use encryption or something like BitLocker simply because it adds too much overhead.
