10.4: Two hints related to swap files
the protected VM is not just for the paranoid. if it's not a big performance hit everyone should use it, dare I say they make it the default ... if you want to see something interesting do a strings command on the VM file ... you can see all sorts of nastiness that you shouldn't be able to like unencrypted usernames/passwords for all users on the machine, regardless of your user access (everyone can read the vm file)

I don't think it's true that all users can read the files. If your permission are correct the Swapfiles are owned by root:wheel and have 0600 permissions, so only root can do anything. |
