All right, let's take a look at Module 12,
which deals with mobile device security.
Right out of the gates, we just got done
talking about wireless security issues and concerns.
Right out of the gates, everything we
talked about in wireless inherently applies to mobile because they
almost use exclusively wireless communications.
Pretty rare that you'll plug in a USB
Ethernet cable to your Android phone or iOS.
It's possible, but it's not likely.
So all of the wireless security issues are concerns.
Getting right out of the gates.
Couple of different connection methods we're going to talk about.
Some may be more dangerous or exploitable than others.
Near field communication employs electromagnetic induction to enable
communication between devices connect with a range of 10 centimeters.
Right.
So they're going to be in pretty close proximity to attack a device using NFC.
Satellite communication.
Artificial geostationary satellites provide services across the globe,
much slower and more expensive than other technologies.
Satellite communication, probably the most
widely used based on a single network tower that
serves devices located within a specific radius.
You also have ANT.
Ant is a wireless sensor, enables
communication between sensors and their controllers.
The best example I can give you of ANT that I've seen personally is the use of
fitness trackers and so forth that use it to transmit heart rates and that thing.
Universal Stereo Bus, pretty self explanatory.
Most are familiar with USB, enables wired communication for devices or can.
Global positioning system, radio
navigation and man, what did we do before Google Maps and GPS?
Remember printing out MapQEST Maps?
And then Infrared IR, which is line of sight, short range of up to five meters,
wireless technology for transferring data between two devices in digital form.
All right, so again, not all this is going to be just for cell phones.
Again, we're talking about any device with a battery qualified as a mobile device.
Wifi, enough said.
We just got done talking about WiFi.
Common wireless technologies in homes and office buildings, we know this.
We just add a whole module on it.
Bluetooth, we also discussed Bluetooth in the previous module.
Short range, high speed, low power,
personal area networks, 802.15 specification.
Then 5G cellular or mobile communication, broadband cellular network, operates at
high bandwidth, low latency, provides high speed data downloads.
I am currently still in the 4G category.
Getting ready for a new phone purchase, though, so getting ready to kick the 5G.
I have not experienced the throughput yet.
