as long as there have been humans around
there have been some criminals also
trying to come up with ways to steal
things from others the term cyber
security which can be defined as the
efforts we take to stop criminals from
stealing things from us through our
computers
is a pretty new term though
and it was only a few years ago that the
most common cyber security threats were
viruses attacking your computer or
emails from royal families around the
world who claimed they had some money
for you
today however cyber security is a very
very big deal
trillions of dollars big and cyber crime
is now the fastest growing industry in
the world
this is because in the past many homes
only had one computer in them
now your phone is a computer your oven
and fridge might be too
people have smart pacemakers pumping
blood around their body or smart contact
lenses in their eyes
they drive their smart cars to work
passing by smart billboards
this idea that there are smart devices
everywhere is often referred to as the
internet of things
and it means that everything that is a
computer that is connected to the
internet can be hacked
there are cases where a group of hackers
worked out how to manipulate electronic
road signs used for temporary roadworks
they changed the signs to read godzilla
attack turn back
the steering wheel stereo and brakes of
a car can be hacked through a laptop
miles away
and a casino can be hacked through its
smart fish tank
more seriously hackers have successfully
penetrated nuclear power stations and
printers in people's homes which is a
challenge when 3d printers start
printing our dinners or our medicine
so a big question you need to ask now is
will criminals be able to hack into your
ai
and if they can
what will they be able to do
