Laptop Data Safety
Submit Articles Back to Articles
Basic levels of password protection on laptops are easily overcome by the
experienced thief and this is causing considerable concern within the industry.
There are two things you should do:
- Physical security - Don't let your laptop out of your sight. Never
leave it unattended in a public place. Never leave it in the boot of your car
overnight at hotels. Always use a steel cable to attach it to a firm structure
when in use outside your normal environment.
- Electronic security - Don't have sensitive data on a hard disk in
the first place. Use a complex password and if possible second level
authentication, such as a token or other device. When the laptop is on but is
not being used, use the electronic lock facility to activate the password
entry facility. Use a password on any screensaver.
That takes some account of security for the laptop, but with attached devices
such as SD cards and USB pen-drives the situation is different:
Anyone stealing the SD Card or Pen-drive can read the data on any computer
loaded with similar software. This is clearly a point of vulnerability; the best
method to protect this type of device is to encrypt it so that it is useless
without the decrypt key.
This protection is not the expensive option it used to be, with open source
software freely available. The best of these encrypt and decrypt on the fly and
are transparent to the authorised but render the device useless to the thief and
in may cases appear to be a blank device.
