Laptop Physical Security

The laptop computer is the best and worst device you could possibly
own, at least from a security perspective. It is the best device in terms of
sheer power and portability. However, it is the worst device because it
can be easily lost and represents a serious gap in your security.

Physical security of your laptop primarily deals with unauthorized
users who acquire your computing device and use it to eavesdrop on or
access wireless network communications. The problem with losing a laptop
is that these types of intrusions are difficult to trace. They could be
coming from inside the network or outside, if your access point has sufficient
transmission power and extends beyond the building perimeter. A
hacker could use a stolen device to listen to your internal network traffic
from the parking lot outside your building without your even knowing
about it.
