3. Introduction
Mobile Device?
 Apocket-sized computing device, typically having adisplay
screen with touch input or aminiaturekeyboard

4. history
It can be said thatthe mobile devices was born at
the same time the radio communication had been
invented.
The development of mobile devices starts fromthe
1920's, there are five stages.

5. Stage One
1920's-1940's
 Based on several wave bands of shortwave, the private mobile
communication system had been invented.
 The Detroit police car radio system is the representative one.
 The frequency of this system is 2MHz at thattime. In the 1940's the
frequency had been risen to 30~40MHz.
 Itis considered as the beginning of the modern mobile service.

6. Stage Two
1940's-1960's
 The public mobile service came out.
 1946 According to the plan of Federal Communications
Commission(FCC) the Bell system established the first public car
phone net inSt.Louis.
 There was three channles in thattime, the mode wassimplex.

7. Stage Three
1960's-1970's
America improved the mobile telephony
system(1MTS)
This period complete :
automatic channel choose
automatic dialing tothenet

8. Stage Four
1970's-1980's( the peak time)
The Bell Labs successfully developed the
advanced mobile phonesystem(AMPS)
The cellular network builtup, improved the
capacity of thesystem.
The cellular network becames the utility system,
used in theworldwide.

9. Stage Four
Achivements in thisstage:
 microelectronic technique got a significant development
which made the probability of miniaturization mobile devices
be true.
 The new system of mobile communication----cellular
network
 provide the technique for the manage and control of the large
size net

10. Stage Five
1980's-
The Digital Mobile Communication System(DMCS)
gets developed and mature in this period.
AMPS & TACS stand for the CellularNetworks

and performing numerous other tasks withvariables.

19. What is mobile operatingsystem?
Amobile operating system, also known asamobile OS, a
mobile platform, or ahandheld operating system, is the
operating system that controls amobile device or
information appliance

31. Future
The mobile devices plays an indispensable role in
nowaday's life, meanwhile this field is still rapidly
developing. More app is going tobe added into.
In 2004 July 16, Japanese telephone company NTT
DoCoMo announced the P605iC phone which carried the
FeliCa soft. This phone opened the curtain of No Cards
Generation.

32. Future
Nowadays the manufactures of mobile devices are
devoting on touching screen and 3D effect.
More and moreAPP will be added intothe mobile devices,
make people's life much more convenient and fun.

33. VISUALIZING MOBILE SECURITY
There are three points of control.
SMART PHONE AND MOBILE DEVICE SECURITY
•
•
•
On the left you have device security, protecting both the device and the data.
On the top right you have mobile application security which includes secure
application development and analyzing applications for security risk.
The bottom right highlights the need for to provide secure access to applications
•
and data.
They are all interlinked and interconnected.

 PC threats in mobile: email, links,brows5
ers,

35. Wi-Fi
Carriers collect WIFI network names/BSSIDs and correlating
GPS data
Fine-tune location
 Can be usedindoors
Google got in trouble in 2010 for collecting data with their
StreetView cars
Decided it was simpler to use mobile devices
Enormous userbase
Constantly updated

36. 5. SMART PHONE & MOBILE DEVICE THREATS
Four MajorActors
 Government agencies
 Carriers/Providers
 Hackers
 Thieves
11

37. HACKERS - TRADITIONAL
 Network-Based
Normal web-based rules apply
Beware public Wi-Finetworks
 App security is getting bettereveryday
 A lot of unencrypted sensitive traffic is still sent and
received
Major hole in iOS7 < 7.0.6 / iOS6 <6.1.6
 70% of Android devices in circulation
Affected by known, remote code execution vulnerability
 Beware QR Codes!

39. a) GPS
 Most obvious
 Pretty accurate outdoors, but not so much indoors
 Very useful
 Third party applications use GPS for correlation
 Sometimes stored locally and accessible.
b) CELL-NETWORK
 Tower Triangulation
 Can be used alongside GPS
 Mandatory use in emergencies
 Law enforcement
 Carriers
 As long as you have a phone, this information is available
 Sometimes legalities or warrants involved

40. b) SOCIAL MEDIA
 The success of mobile devices and global rise of socialmedia
are unquestionably intertwined
Outside of the obvious personal data
Geo-tagged updates on Facebook andTwitter
Facebook Graph search makes hiding online much more
difficult
LinkedIn open by default
Useful tool for social engineers
 Site is scraped for names and corporate structure 10
