”If you’re a researcher on this book thing and you were on Earth,
you must have been gathering material on it.”
”Well, I was able to extend the original entry a bit, yes.”
”Let me see what it says in this edition, then. I’ve got to see it.”
... ”What? Harmless! Is that all it’s got to say? Harmless! One word!
... Well, for God's sake I hope you managed to rectify that a bit.”
”Oh yes, well I managed to transmit a new entry off to the editor. He
had to trim it a bit, but it’s still an improvement.”
”And what does it say now?” asked Arthur.
”Mostly harmless,” admitted Ford with a slightly embarrassed
cough.

IoT from a hacker’s perspective

Internet of Things
cheap (in every sense)
computers easy to compromise
now easily searchable and
accessible remotely

Security economics
24
vendors build
cheap devices
maximize profit
minimize time to market
more features, no security
consumers buy
cheap devices
optimize price/value ratio
don’t understand the risk
can’t identify quality
misplaced incentives
makes no sense to build
secure devices
lemon market:
information asymmetry
consumers will pay average price
quality vendors leave the market
