Security Lessons from a Power Saw
Lance Spitzner looks at the safety features of a power saw and tries to apply them to Internet security:
By the way, here are some of the key safety features that are built into the DeWalt Mitre Saw. Notice in all three of these the human does not have to do anything special, just use the device. This is how we need to think from a security perspective.
- Safety Cover: There is a plastic safety cover that protects the entire rotating blade. The only time the blade is actually exposed is when you lower the saw to actually cut into the wood. The moment you start to raise the blade after cutting, the plastic cover protects everything again. This means to hurt yourself you have to manually lower the blade with one hand then insert your hand into the cutting blade zone.
- Power Switch: Actually, there is no power switch. Instead, after the saw is plugged in, to activate the saw you have to depress a lever. Let the lever go and saw stops. This means if you fall, slip, blackout, have a heart attack or any other type of accident and let go of the lever, the saw automatically stops. In other words, the saw always fails to the off (safe) position.
- Shadow: The saw has a light that projects a shadow of the cutting blade precisely on the wood where the blade will cut. No guessing where the blade is going to cut.
Safety is like security, you cannot eliminate risk. But I feel this is a great example of how security can learn from others on how to take people into account.

the problem in communications is a bit different: where we generally fail is our FAILURE to AUTHENTICATE
we answer phone calls with no clue as to who is calling — an invitation to the scamsters and grifters;
for computer based communication the problem goes deeper: we must authenticate SOFTWARE as well as callers & contacts
we’re in a tough spot: the megacorps want everything “easy-peasey”: as soon as you see that Tickle-me-Elmo they want that plastic card in the slot
and there was too much influence being bought,….. down on “K-Street”
