Bruce Schneier blogs on the possibility of a public tweet leading to a burglary. This got me to mark down some thoughts that I have for quite some time regarding home Wi-Fi networks:
While a simple curtain can keep the nosy neighbor in the dark, Wi-Fi cannot be “curtained”. If our access point is not on all the time, the neighbor knows when we are on the Net. It is even easy to know this even when the AP is always on, since it is the activity that matters. Hell, they can even be patient enough to crack our keys and look around. And it is quite possible that a burglar knows when we are at home, or on vacation by simply observing whether the AP is on or active based on the usage pattern that we create.
[ Update: The post’s point is that wireless devices inside the house reveal habits of ours to the neighborhood that we *think* are not since we have drawn the curtains. Plus, stuff like WPA protects us from the passer-by and not from the nosy neighbor. ]
Oh well, I guess I cannot be paranoid enough, right?
