How Travelers Can Protect Their Data

Filed under
Security

This post is not meant to be a sure method for defeating attackers. That you can make the process so tedious and time consuming for the attacker, that he will likely not bother and move to another victim. This post is about those methods.

STEP ONE: Prepare your hard drive.

The goal of this step is to install an encrypted filesystem. So, before we do that, we need to do some preparation. In order to get to that point, you will need to write random or pseudorandom data to the entire disk. This will take some time. My experience has show that laptop drives usually operate around 30MBps, so if you have a 300GB drive, this will take you just under 3 hours. The reason for doing this is to confuse the attacker just exactly where the encrypted filesystems reside. If the entire disk is underlined with random or pseudorandom data (it doesn’t necessarily need to be cryptographically secure here), then when looking at the drive level, it will be practically improbable to determine where the encrypted filesystem starts and where it ends. If you skip this step, then it’s quite obvious, and rather than wast his time on the entire disk, the attacker can focus his efforts on just the obvious encrypted portions of the disk.

PC-BSD Becomes TrueOS, FreeBSD 11.0 Reaches RC2

  • More Details On PC-BSD's Rebranding As TrueOS
    Most Phoronix readers know PC-BSD as the BSD operating system derived from FreeBSD that aims to be user-friendly on the desktop side and they've done a fairly good job at that over the years. However, the OS has been in the process of re-branding itself as TrueOS. PC-BSD has been offering "TrueOS Server" for a while now as their FreeBSD-based server offering. But around the upcoming FreeBSD 11.0 release they are looking to re-brand their primary desktop download too now as TrueOS.
  • FreeBSD 11.0-RC2 Arrives With Fixes
