information systems access in the cybercrime world.
• Understand challenges faced by the mobile workforce and
implication under the cybercrime era.
• Mitigation strategy – credit card users.
• Security issues due to use of media players.
• Organizational security implications with electronic gadgets.
• Organizational measures for protecting information systems from
threats in mobile computing area.
• Smishing, vishing attacks in mobile world.
• Security issues arising due to use of removable media- pen drives

Proliferation of mobile and wireless devices
• You see them everywhere: people hunched over their smartphones
or tablets in cafes, airports, supermarkets and even at bus stops,
seemingly oblivious to anything or anyone around them.
• They play games, download email, go shopping or check their
bank balances on the go.
• They might even access corporate networks and pull up a
document or two on their mobile gadgets.

Types of Mobile Computer
Many types of mobile computers have been introduced since
1990, as follows;
• Portable computer
• Tablet PC
• Internet Tablet
• PDA
• Ultramobile PC
• Smartphone
• Carputer
• Fly fusion Pen top computer

Mobile, Wireless Devices and hand-held devices

• But as wireless devices become increasingly ingrained into our
daily lives, they open the door to heightened security risks.
• Not only do such devices become points of access for
cybercriminals, but they also may be more easily breached than
personal computers since many consumers do not secure their
smartphones or tablets with antivirus software or take simple
precautions such as enabling password protection.
Security?

Risk factors
The dangers, of course, are plenty;
• Rogue mobile apps can record the information that users
type into a device, such as bank account numbers and
PINs.
•
• They can read data stored on a handset, such as emails, text
messages, attachments, credit card numbers, and log-ins
and passwords to corporate networks.
• A phone can even secretly record conversations within
earshot.

• Data that leaves a mobile device wirelessly to connect to a
Wi-Fi network could be hijacked in mid-air in “man in the
middle” attacks.
• Consumers may not be as concerned about securing a
wireless device because they do not view it as a small
computer. “They think, ‘Oh, it’s just my phone.
• The risks are transferred to the workplace as more people
bring their devices to the office for both personal and
professional use, a phenomenon known as BYOD or
“Bring Your Own Device.”
Risk factors

Key Findings for Mobile Computing Security Scenario
1. With usage experience, awareness of mobile users gets
enhanced
2. People continue to remain the weakest link for laptop
security
3. Wireless connectivity does little to increase burden of
managing laptops
4. Laptop experience changes the view of starting a smart
hand-held pilot
5. There is naivety and/or neglect in smart hand-held
security
6. Rules rather than technology keep smart hand-helds’
usage in check

Attacks against 3G mobile networks
• Malware, viruses and worms
• Skull trojans
• Cabir worm
• Mosquito worm
• Denial-of-service
• Overbilling attack
• Spoofed policy development process
• Exploits vulnerabilities of GTP (GPRS Tunneling Protocol)
• Signaling-level attacks
• Exploits vulnerabilities of SIP (Session Initiation Protocol)
used in IP Multimedia Subsystem (IMS) network to
provide VoIP services.

• A trojan horse piece of code that targets mainly Symbian
OS.
• Once downloaded, the virus replaces all phone desktop
icons with images of a skull.
• It also renders all phone applications useless.
• This malware also tends to mass text messages containing
malicious links to all contacts accessible through the
device in order to spread the damage.
• This mass texting can also give rise to high expenses.
Skull trojan

• This malware infects mobile phones running on Symbian
OS and was first identified in June 2004.
• When a phone is infected, the message 'Caribe' is
displayed on the phone's screen and is displayed every
time the phone is turned on.
• The worm then attempts to spread to other phones in the
area using wireless Bluetooth signals, although the
recipient has to confirm this manually.
Cabir worm

• In June 2004, it was discovered that a company called
Ojam had engineered an anti-piracy Trojan virus in
older versions of its mobile phone game, Mosquito.
• This virus sent SMS text messages to the company
without the user's knowledge.
• Although this malware was removed from the game's
more recent versions, it still exists in older, unlicensed
versions, and these may still be distributed on file-
sharing networks and free software download web
sites.
Mosquito worm

Mobile Vulnerabilities
• Mobile devices often do not have passwords enabled.
• Two-factor authentication is not always used when conducting
sensitive transactions on mobile devices.
• Wireless transmissions are not always encrypted
• Mobile devices may contain malware.
• Mobile devices often do not use security software.
• Operating systems may be out-of-date.
• Software on mobile devices may be out-of-date
• Mobile devices often do not limit Internet connections.
• Mobile devices may have unauthorized modifications.
• an unsecured WiFi network could let an attacker access personal
information from a device, putting users at risk for data and
identity theft.

• According to a Harris Interactive survey commissioned by CTIA,
a wireless trade group,
• less than half of all wireless device owners use passwords or
personal identification numbers (PINs) on their handsets
• Among those who conduct online banking on mobile devices,
only half encrypt the data or use some form of security
software.
• Moreover, less than one third of users have installed antivirus
software on their mobile devices compared to 91% on their
laptops.
• This may explain why: 45% do not see cybersecurity on their
mobile devices as a threat in the same way as they see it on
their computers
Mobile Users’ Tendency

Credit Card Fraud
1. Traditional technique
• Application fraud: paper-based fraud, where in a
criminal uses stolen or fake document to open an
account on someone else name.
• Application frauds can be divided in to;
• ID theft
• Financial Fraud where an individual gives false info
about his financial status to acquire credit.

2. Modern technique: sophisticated techniques
enables criminals to produce fake and doctored cards.
These are those who use skimming.
• Triangulation
• Credit Card generators
Credit Card Fraud

Security challenges posed by mobile devices:
• One at the device level: microchallenges
• Another at the organization level: macrochallenges

Well know challenges in mobile security:
• Managing the registry setting and configuration
• Authentication Service Security
• Cryptography Security
• Lightweight Directory Access protocol(LDAP)
Security
• Remote Access Server(RAS) security
• Media Player Control Security
• Network Application Program Interface (API) security

Registry settings for mobile devices
• Microsoft ActiveSync : is meant for synchronization with
PCs and MS Outlook
• It acts as Gateway between Windows-Powered PC and
Windows mobile-Powered device, enabling transfer of
Outlook information, MS Office documents, pictures,
music, videos and applications from user’s desktop to his
device.
• ActiveSync can synchronize directly with MS Exchange
Sever so that the user can keep their E-Mails, calendar,
notes and contacts updated wirelessly.

Managing the registry setting and configuration
• If you use an Active Directory® environment to administer the computers in your
network, Group Policy provides a comprehensive set of policy settings to manage
Windows® Internet Explorer® 8 after you have deployed it to your users'
computers.
• You can use the Administrative Template policy settings to establish and lock
registry-based policies for hundreds of Internet Explorer 8 options, including
security options.
• 1700 settings in a standard group policy
• Even if the user go through every control panel setting and group policy option-
no desired baseline security
• So make additional registry changes that are not exposed to any interface: avoid
“registry hacks”

Authentication Service Security
• There are two components of security in mobile
computing:
• security of devices and
• security in networks.
• A secure network access involves mutual authentication
between the device and the base stations or Web servers.
This is to ensure that only authenticated devices can be
connected to the network
• Therefore, no Malicious Code can impersonate the
service provider to trick the device into doing something
wrong.

• Thus, the networks also play a crucial role in security of
mobile devices.
• Some eminent kinds of attacks to which mobile devices are
subjected to are:
• push attacks,
• pull attacks and
• crash attacks.

• Authentication services security is important given the
typical attacks on mobile devices through wireless
networks:
• DoS attacks,
• traffic analysis,
• eavesdropping,
• man- in-the-middle attacks and
• session hijacking.

Cryptographic Security for Mobile Devices
• We will discuss a technique known as cryptographically generated
addresses (CGA).
• CGA is Internet Protocol version 6 (IPv6) that addresses up to 64
address bits that are generated by hashing owner’s public-key
address.
• The address the owner uses is the corresponding private key to
assert address ownership.
• To sign messages sent from the address without a Public-Key
Infrastructure(PKI)
• CGA-based Authentication can be used to protect IP-Layer signaling
protocols
• Also used in key –exchange and create an IPSec security
association for encryption and data authentication

• Cryptographic Provider Manage(CPM) in Palm OS5 is
a system-wide suite of cryptographic services for
securing data and resources on a Palm- powered device
Example: Palm OS5

• LDAP is a software protocol for enabling anyone to
locate individuals, organizations and other resources like
files and devices on the network
• LDAP is light weight version of Directory Access
Protocol(DAP) since it does not include security features
in its initial version.
• It originated at the University of Michigan
• Endorsed by atleast 40 companies
• Centralized directories such as LDAP make revoking
permissions quick and easy.
LDAP security for hand held mobile computing devices

• RAS is important for protecting business sensitive data
that is reside on the employee’s mobile devices.
• Vulnerable to unauthorized access : resulting in
providing a route into the systems with which they
connect
• By impersonating or masquerading to these systems,
a cracker is able to steal data or compromise
corporate systems in other ways.
• Another threat is by port scanning: DNS server- locate IP
address- scan the port on this IP address that are
unprotected.
• Precautions: a personal firewall
RAS security for mobile devices

Media Player Control Security
• Given the lifestyle of today’s young generation, it is quite common to
expect them embracing the mobile hand-held devices as a means for
information access, remote working and entertainment.
• Music and video are the two important aspects in day-to-day aspects
for the young generation.
• Given this, it is easy to appreciate how this can be a source for cyber
security breaches.
• Various leading software development organizations have been
warning the users about the potential security attacks on their mobile
devices through the “music gateways.”

• There are many examples to show how a media player can turn out
to be a source of threat to information held on mobile devices.
• For example, in the year 2002, Microsoft Corporation warned about
this.
• According to this news item, Microsoft had warned people that a
series of flaws in its Windows Media Player could allow a malicious
hacker to hijack people’s computer systems and perform a variety of
actions.
• According to this warning from Microsoft, in the most severe exploit
of a flaw, a hacker could take over a computer system and perform
any task the computer’s owner is allowed to do, such as opening
files or accessing certain parts of a network.
Media Player Control Security

Networking API Security for Mobile Computing Applications
• With the advent of electronic commerce (E-Commerce) and its
further off-shoot into M- Commerce, online payments are becoming
a common phenomenon with the payment gateways accessed
remotely and possibly wirelessly.
• With the advent of Web services and their use in mobile computing
applications consideration.
• Already, there are organizations announcing the development of
various APIs to enable software and hardware developers to write
single applications that can be used to target multiple security
platforms present in a range of devices such as mobile phones,
portable media players, set-top boxes and home gateways.

• Most of these developments are targeted specifically at securing a
range of embedded and consumer products, including those
running OSs such as Linux, Symbian, Microsoft Windows CE and
Microsoft Windows Mobile (the last three are the most commonly
used OSs for mobile devices).
• Technological developments such as these provide the ability to
significantly improve cyber security of a wide range of consumer
as well as mobile devices.
• Providing a common software framework, APIs will become an
important enabler of new and higher value services.
Networking API Security for Mobile Computing Applications

Attacks on Mobile/ cell phones
• Mobile Phone Theft
• Mobile Viruses
• Mishing
• Vishing
• Smishing
• Hacking bluetooth

With mobiles or cell phones becoming fancier, more popular, and
more expensive, they are increasingly liable to theft.
The following factors contribute for outbreaks on mobile devices:
1. Enough target terminals: first mobile virus in 2004 :- Mosquito
– this virus sent SMS text messages to the organization(Ojam)
2. Enough functionality: office functionality, critical data and
applications protected insufficiently or not at all.
expanded functionality increases the probability of malware
3. Enough connectivity: SMS, MMS, Synchronization, bluetooth,
infrared(IR) and WLAN connections
Mobile phone theft

• Keep details. Make a record of all your phone
information and keep this in a safe place. Include the
following elements in the information: Your phone
number
• The make and model
• Color and appearance details
• The pin or security lock code
• The IMEI number (on GSM phones)
• International Mobile Equipment Identity
How to Protect a Mobile Phone from Being Stolen

• Add a security mark. Use an ultra-violet pen to print
your post code and house number onto both your mobile
handset and battery. This makes it easily identifiable as
your property if lost or stolen. It would also be good if
you write your alternate contact number or email id on
your phone.
• This would help the finder of your handset to contact
you if he or she intents to return it. The ultra-violet pen
marking will wear off every couple of months, so reapply
it when you feel necessary.

• Use the security lock code, or PIN feature, to lock
your phone. This will make it less valuable to a thief
and deny them access to personal numbers stored on
your SIM card.

• Register your phone with your network operator. If your phone
is stolen, report the loss to them immediately.
• Using your IMEI number, they may be able to block your hand set
and account details.
• Some wireless carriers are willing to do this, and some aren’t.
• If done, this will prevent anyone from using the phone across any
network, even if the SIM card is changed.
• Keep in mind that once the phone is disabled, it may not be able to
be used again, even if you get it back.
• Keep records of this call--the date, time, name of the person you
spoke to, what they said, and their extension.
• Ask for confirmation in writing that your phone has been disabled.
• This is important in case the thief makes fraudulent charges on
your account.

• Have your phone number disabled. In addition to reporting your
phone lost or stolen, you should also disable your phone number
(not account) so that no further charges can be applied.
• This is in case the thief figures out how to access your account
through another hand set, or in case the carrier is unwilling to
block the handset.
• Remember that, as mentioned earlier, many thieves stand to
benefit from using your service rather than selling your phone,
especially between the moment they steal it and the moment you
realize your phone is missing.
• As in the previous step, keep detailed records of when you
requested your account to be disabled.

• Request an immediate, formal investigation from your carrier.
Sometimes this can prevent (or at least delay) the carrier from
launching a collections effort and tainting your credit, if things get
ugly.
• File a police report immediately. Time is money, literally. A thief
can add over US$10,000 to your cell phone bill in just hours by
making international calls, and you might end up being asked to
foot the bill.
• Some phone companies may require proof that the phone was
actually stolen, versus it having been lost.
• A police report serves as evidence, which will make your wireless
provider more cooperative, especially if insurance is involved.

• Install anti phone theft software. There are suppliers that provide
modern anti theft software for your phone.
• The software enables you to remotely contact your mobile and stay
in control.
• For example, one of the recently published solutions for Symbian
and Android is Theft Aware; others provide Windows Mobile or
Blackberry support
• Never let the phone get out of your sight. Unless you are
sleeping of course, always have your eyes on the phone.

Mobile Viruses
• A mobile virus is similar to a computer virus that targets mobile
phone data or applications/software installed in it.
• Virus attacks on mobile devices are no longer an exception or
proof-of-concept nowadays.
• In total, 40 mobile virus families and more than 300 mobile viruses
have been identified.
• First mobile virus was identified in 2004 and it was the beginning
to understand that mobile devices can act as vectors to enter the
computer network.

• Mobile viruses get spread through two dominant communication
protocols – Bluetooth and MMS.
• Bluetooth virus can easily spread within a distance of 10–30 m,
through Bluetooth- activated phones (i.e., if Bluetooth is always
ENABLED into a mobile phone) whereas MMS virus can send a
copy of itself to all mobile users whose numbers are available in
the infected mobile phone’s address book.
Mobile Viruses

1. Download or accept programs and content (including ring
tones, games, video clips and photos) only from a trusted
source.
2. If a mobile is equipped with Bluetooth, turn it OFF or set
it to non-discoverable mode when it is not in use and/or
not required to use.
3. If a mobile is equipped with beam (i.e., IR), allow it to
receive incoming beams, only from the trusted source.
4. Download and install antivirus software for mobile
devices.
Some tips to protect mobile from mobile malware attacks

• Forwarded messages claim that a destructive virus will
infect your mobile (cell) phone if you receive a call that
displays "ACE" or "XALAN" on the screen.
Mobile Phone Virus Hoax

• All mobile users pay attention!!!!!!!!!
If you receive a phone call and your mobile phone displays(XALAN)on the
screen don't answer the call, END THE CALL IMMEDIATELY,if you answer
the call,your phone will be infected by a virus. This virus WILL ERASE all
IMEI and IMSI information from both your phone and your SIM card, which
will make your phone unable to connect with the telephone network. You will
have to buy a new phone. This information has been confirmed by both
Motorola and Nokia. There are over 3 Million mobile phones being infected by
this virus in all around the world now. You can also check this news in the CNN
web site.
PLEASE FORWARD THIS PIECE OF INFORMATION TO ALL YOUR
FRIENDS HAVING A MOBILE PHONE.

• Mishing is a combination of mobile phone and Phishing Mishing
attacks are attempted using mobile phone technology.
• Commerce is fast becoming a part of everyday life. If you use your
mobile phone for purchasing goods/services and for banking, you
could be more vulnerable to a Mishing scam.
• A typical Mishing attacker uses call termed as Vishing or message
(SMS) known as Smishing.
• Attacker will pretend to be an employee from your bank or another
organization and will claim a need for your personal details.
• Attackers are very creative and they would try to convince you with
different reasons why they need this information from you.
Mishing

Vishing
• Vishing is the criminal practice of using social
engineering over the telephone system, most often using
features facilitated by VoIP, to gain access to personal
and financial information from the public for the
purpose of financial reward.
• The term is a combination of V – voice and Phishing.
• Vishing is usually used to steal credit card numbers or
other related data used in ID theft schemes from
individuals.

The most profitable uses of the information gained through
a Vishing attack include
1. ID theft;
2. Purchasing luxury goods and services;
3. Transferring money/funds;
4. Monitoring the victims’ bank accounts;
5. Making applications for loans and credit cards.
Vishing

• A vishing perpetrator (visher) may gain access to a group
of private customer phone numbers.
• The visher may then call the group(may use war dialer)
• When a potential victim answers the phone, he or she
hears an automated recording informing him that his
bank account has been compromised.
• He then calls the specified toll-free number to reset his
security settings and hears another automated message
requesting the user’s bank account number and/or other
personal details via the phone keypad..
How Vishing works?

How to Protect from Vishing Attacks
Following are some tips to protect oneself from Vishing
attacks.
1. Be suspicious about all unknown callers.
2. Do not trust caller ID. It does not guarantee whether
the call is really coming from that number, that is,
from the individual and/or company – caller ID
Spoofing is easy.
3. Be aware and ask questions, in case someone is
asking for your personal or financial information.
4. Call them back.
5. Report incidents to cybercell.

Smishing
• Smishing is a criminal offense conducted by using social
engineering techniques similar to Phishing.
• The name is derived from“SMSPhISHING.”
• SMS can be abused by using different methods and
techniques other than information gathering under
cybercrime.
• SMS phishing made recent headlines when a
vulnerability in the iPhone's SMS text messaging system
was discovered that made smishing on the mobile device
possible.

• Smishing scams frequently seek to direct the text
message recipient to visit a website or call a phone
number, at which point the person being scammed is
enticed to provide sensitive information such as credit
card details or passwords.
• Smishing websites are also known to attempt to infect
the person's computer with malware.
How smishing works?

Following are some tips to protect oneself from Smishing attacks:
1. Do not answer a text message that you have received asking for
your PI.
2. Avoid calling any phone numbers, as mentioned in the received
message, to cancel a membership and/or confirming a transaction
which you have not initiated but mentioned in the message.
3. Always call on the numbers displayed on the invoice and/or
appearing in the bank statements/passbook.
4. Never click on a hot link received through message on your
Smartphone or PDA. Hot links are links that you can click, which
will take you directly to the Internet sites.

1. Bluetooth is an open wireless technology standard used for
communication (i.e., exchanging data) over short distances
between fixed and/or mobile devices.
2. Bluetooth is a short-range wireless communication
service/technology that uses the 2.4- GHz frequency range for its
transmission/communication.
Bluetooth

• Bluetooth hacking is a technique used to get information from
another Bluetooth enabled device without any permissions from
the host.
• This event takes place due to security flaws in the Bluetooth
technology.
• It is also known as Bluesnarfing.
• Bluetooth hacking is not limited to cell phones, but is also used
to hack PDAs, Laptops and desktop computers.
• Bluetooth hacking is illegal and can lead to serious
consequences.
Bluetooth Hacking

• The hacker can steal, delete contacts.
• Hacker can extract personal files/pictures etc.
• Your cell phone can be used for making calls and using internet at
your expense.
• The hacker may call or text your contacts to annoy them.
• Your mobile phone can be reset to default factory settings hence
deleting your personal settings.
• Hacker can even access your calendar, clock, International Mobile
Equipment Identity (IMEI) number.
• IMEI number can be used to clone your cell phone so that your
messages are also routed to another number. Cloning is also
considered illegal.
Threats of Bluetooth Hacking

• Bluejacking:
• Bluesnarfing
• Bluebugging
• Car wishper
Common Bluetooth attacks

• Bluejacking is the sending of unsolicited messages over
Bluetooth to Bluetooth-enabled devices such as mobile
phones, PDAs or laptop computers, sending a vCard
which typically contains a message in the name field
(i.e., for bluedating or bluechat) to another Bluetooth-
enabled device .
• Bluejacking is also known as bluehacking.
• Bluejacking exploits a basic Bluetooth feature that
allows devices to send messages to contacts within
range.
• Bluejacking is harmless
Bluejacking

• Bluesnarfing is the unauthorized access of information
from a wireless device through a Bluetooth connection,
often between phones, desktops, laptops, and PDAs
(personal digital assistant.).
• This allows access to a calendar, contact list, emails and
text messages, and on some phones, users can copy
pictures and private videos.
• Both Bluesnarfing and Bluejacking exploit others'
Bluetooth connections without their knowledge.
• While Bluejacking is essentially harmless as it only
transmits data to the target device, Bluesnarfing is the
theft of information from the target device.
Bluesnarfing

• Bluebugging is a form of Bluetooth attack often caused by a lack of
awareness.
• It was developed after the onset of bluejacking and bluesnarfing.
• Similar to bluesnarfing, bluebugging accesses and uses all phone
features
• Bluebugging manipulates a target phone into compromising its
security, this to create a backdoor attack before returning control of
the phone to its owner.
• Once control of a phone has been established, it is used to call back
the hacker who is then able to listen-in to conversations.
• The Bluebug program also has the capability to create a call
forwarding application whereby the hacker receives calls intended for
the target phone.
• Hacker can send messages, read phonebooks, and examine calendars.
Bluebugging

• Software that intercepts a hands-free Bluetooth
conversation in a car.
• Car Whisperer enables an attacker to speak to the driver
as well as eavesdrop on a conversation.
• By exploiting the fact that a common security code
(passkey) is used by many Bluetooth hands-free system
vendors, the Car Whisperer sets up a two-way session
with the car and a Linux computer.
• An attacker could access a telephone address book once
he has connected with the Bluetooth system,
• May disable airbags or breaks
Car Whisperer

• BTScanner
• Bluesnarfer
• Bluediving
• Blue bugger
• bluesniff

Mobile Devices: Security Implications for
Organizations
1. Managing diversity and proliferation of Hand-Held
devices
2. Unconventional/ stealth storage devices
3. Threat through lost and stolen devices
4. Protecting data on lost devices
5. Educating the laptop users

• Employees aren't just bringing their mobile devices to the
workplace—they're living on them
• As smartphones and tablets become constant
companions, cyber attackers are using every avenue
available to break into them.
• With the right equipment, hackers can gain access to a
nearby mobile device in less than 30 seconds and then;
• either mirror the device and see everything on it, or
• install malware that will enable them to siphon data
from it at their leisure.
1. Managing diversity and proliferation of
Hand-Held devices

• Analysts predict that, 25 percent of corporate data will completely
bypass perimeter security and flow directly from mobile devices to
the cloud.
• Chief information security officers (CISOs) and other security
executives are finding that the proliferation of mobile devices and
cloud services are their biggest barriers to effective breach response.
• Given the threats to information systems through usage of mobile
devices, the organizations need to establish security practices at a
level appropriate to their security objectives, subject to legal and
other external constraints.
1. Managing diversity and proliferation of
Hand-Held devices

• We would like to emphasize upon widening the spectrum of mobile
devices and focus on secondary storage devices, such as CDs, USB
drives used by employees.
• As the technology is advancing, the devices continue to decrease in
size and emerge in new shapes and sizes – unconventional/stealth
storage devices available nowadays are difficult to detect and have
become a prime challenge for organizational security.
• Firewall n antivirus are no defense against the threats by open USB
ports.

Fig: Unconventional/stealth storage devices.

To control over unauthorized access to plug and play devices, solution
is “DeviceLock” softwares. The features of the software allows
system administrator to:
1. Monitor which users or groups can access USB Ports,
2. Wi-Fi and Bluetooth adapters, CD read-only memories (CD-
ROMs) and other removable devices.
3. Control the access to devices depending on the time of the day
and day of the week.
4. Create the white list of USB devices which allows you to
authorize only specific devices that will not be locked
regardless of any other settings.
5. Set devices in read-only mode.
6. Protect disks from accidental or intentional formatting.

• This is a new emerging issue for cyber security.
• Often mobile hand-held devices are lost while people are
on the move.
• Lost mobile devices are becoming even a larger security
risk to corporations.
• A report based on a survey of London’s 24,000 licensed
cab drivers quotes that 2,900 laptops, 1,300 PDAs and
over 62,000 mobile phones were left in London in cabs
in the year 2001 over the last 6-month period.
3. Threats through lost and stolen devices

4. Protecting data on lost devices
• At an individual level, employees need to worry about this.
• 2 reasons cybersecurity need to address this issue;
• Data persistently stored on devices and,
• Always running applications.
• To protect stored data on device 2 precautions can be taken by
individuals;
• Encrypting sensitive data and,
• Encrypting entire file system.
• A key point is that organization should have clear policy on how to
respond to the loss or theft of a device.
• There should be method for device owner to quickly report the loss
and device owner should be aware of this method.

5. Educating the laptop users
• Often it so happens that corporate laptop users could be putting
their company’s networks at risk by down- loading non-work-
related software capable of spreading viruses and Spyware.
• No free downloads
• Illegal music files and movies
• But survey say that 86% employees do this.

Organizational Measures for Handling
Mobile Devices-Related Security Issues
In this we discuss what organizations can do toward
safeguarding their information systems in the mobile computing
paradigm.
• Encrypting Organizational Databases
• Including Mobile Devices in Security Strategy

• Critical and sensitive data reside on databases [say, applications
such as CRM that utilize patterns discovered through data
warehousing and data mining (DM) techniques] and with the
advances in technology, access to these data is not impossible
through hand-held devices.
• It is clear that to protect the organizations’ data loss, such databases
need encryption.
• Two algorithms that are typically used to implement strong
encryption of database files;
• Rijindael
• AES (block encryption algorithm)
• The other algorithm is Multi-Dimensional Space Rotation(MDSR)
algorithm developed by Casio.
Encrypting Organizational Databases

Including Mobile Devices in Security Strategy
• The discussion so far makes a strong business case – in recognition
of the fact that our mobile workforce is on the rise, organizational
IT departments will have to take the accountability for cyber
security threats that come through inappropriate access to
organizational data from mobile-device–user employees.
• Encryption of corporate databases is not the end of everything.

A few things that enterprises can use are:
1. Implement strong asset management, virus checking, loss
prevention and other controls for mobile systems that will prohibit
unauthorized access and the entry of corrupted data.
2. Investigate alternatives that allow a secure access to the company
information through a firewall, such as mobile VPNs.
3. Develop a system of more frequent and thorough security audits
for mobile devices.
4. Incorporate security awareness into your mobile training and
support programs so that everyone understands just how important
an issue security is within a company’s overall IT strategy.
5. Notify the appropriate law-enforcement agency and change
passwords. User accounts are closely monitored for any unusual
activity for a period of time.
Including Mobile Devices in Security Strategy

Organizational Security Policies and
Measures in Mobile Computing Era
1. Importance of Security Policies relating to Mobile
Computing Devices
2. Operating Guidelines for Implementing Mobile Device
Security Policies
3. Organizational Policies for the Use of Mobile Hand-
Held Devices

1. Importance of Security Policies relating to
Mobile Computing Devices
• People (especially, the youth) have grown so used to their handhelds
that they are treating them like wallets!
• The survey asked the participants about the likelihood of six
separate scenarios involving the use of cell phones to communicate
sensitive and confidential information occurring in their
organizations.

The scenarios described the following:
1. A CEO’s administrative assistant uses a cell phone to arrange
ground transportation that reveals the CEO’s identity and location.
2. The finance and accounting staff discusses earnings of press release
and one participant on the call is using a cell phone.
3. A conference call among senior leaders in the organization in which
cell phones are sometimes used.
4. A sales manager conducting business in Asia uses, his/her cell
phone to communicate with the home office.
5. An external lawyer asks for proprietary and confidential
information while using his cell phone.
6. A call center employee assists a customer using a cell phone to
establish an account and collects personal information (including
SSN).

Mobile Computing Devices

2. Operating Guidelines for Implementing Mobile
Device Security Policies
1. Determine whether the employees in the organization need to use
mobile computing devices at all, based on their risks and benefits
within the organization, industry and regulatory environment.
2. Implement additional security technologies, as appropriate to fit
both the organization and the types of devices used.
3. Standardize the mobile computing devices and the associated
security tools being used with them. As a matter of fundamental
principle, security deteriorates quickly as the tools and devices used
become increasingly disparate.
4. Develop a specific framework for using mobile computing devices,
including guidelines for data- syncing, the use of firewalls and anti-
malware software and the types of information that can be stored on
them.

5. Centralize management of your mobile computing devices.
Maintain an inventory so that you know who is using what kinds
of devices.
6. Establish patching procedures for software on mobile devices. This
can often be simplified by integrating patching with syncing or
patch management with the centralized inventory database.
7. Label the devices and register them with a suitable service that
helps return recovered devices to the owners.
8. Establish procedures to disable remote access for any mobile
devices reported as lost or stolen. Many devices allow the users to
store usernames and passwords for website portals, which could
allow a thief to access even more information than on the device
itself.

9. Remove data from computing devices that are not in use or before
re-assigning those devices to new owners (in case of company-
provided mobile devices to employees). This is to preclude
incidents through which people obtain “old” computing devices
that still had confidential company data.
10. Provide education and awareness training to personnel using
mobile devices. People cannot be expected to appropriately secure
their information if they have not been told how.

3. Organizational Policies for the Use of Mobile
Hand-Held Devices
• Securing mobile devices is creating company policies
that address the unique issues these devices raise.
• Such questions include what an employee should do if a
device is lost or stolen.
• There are many ways to handle the matter of creating
policy for mobile devices.
• One way is creating a distinct mobile computing policy.
• Another way is including such devices under existing
policy.

Laptops
Physical security counter measures
1. Cables and hardwires locks
2. Laptop safes
3. Motion sensors and alarms
4. Warning labels and stamps
5. Other measures for protecting laptops such as;
1. Engraving the laptop with personal details
2. Keeping the laptop close to oneself wherever possible
3. Carrying laptops in a different and unobvious bags
