Try thinking of your notebook or mini-note not as a computer but as a pile of cash. Would you leave $800 lying around on a library table or the front seat of your car? How about $300? Chances are you wouldn’t, and that’s because we instinctively realize that’s tantamount to inviting unscrupulous types to help themselves.
Mobile PC Security Tips: Part I
This article offers some straightforward security tips, but the best one is unsaid.
Make it so you do not care whether your laptop is stolen. Take the normal physical security precautions, but make best use of the Cloud to ensure that if the laptop is lost or destroyed, that you do not lose any data. This is done via file sync systems such as Mesh, Live Sync or others, or by using Gladinet to give folder level access to online storage mechanisms like Google Docs, Amazon S3, or Skydrive. What about security of the data – well make sure you use full disk encyption for the laptop so nothing on the disk is recoverable without the password.
And then we come to the cost… well use low cost laptops or netbooks at less than €400/£400 or much less, so the biggest cost is actually the installation of a new machine.
These are what I can recommend, think about it.
