Securing Mobile Devices

Simplifying Security.

Module 13


2/50


Mobile security is the new malware battlefield as attackers take advantage

of users who don’t think their smartphones can get compromised.

Cyber‐attackers are gunning for Google’s Android as they take advantage of

a user base that is “unaware, disinterested or uneducated” in mobile

security, according to a recent research report.

Malware

developers

are

increasingly

focusing

on

mobile

devices,

and

Android malware has surged 400 percent since summer 2010, according to

the Malicious Mobile Threats Report 2010/2011 released May 11. The

increase in malware is a result of users not being concerned about security,

large number of downloads from unknown sources and the lack of mobile

security software, according to the Juniper Networks Global Threat Center,

which compiled the report.

“That’s where the momentum is for 2011,” said Dan Hoffman, Juniper’s chief mobile security evangelist. It’s important to remember that mobile

malware still accounts for less than 1 percent of all malware detected

globally.

(Reuters) ‐ Hackers are increasingly aiming attacks at smartphones, touching off a race

among software

giants,

startups

and

telecom

operators

seeking

to

cash

in

on

ways

to

help

consumers protect themselves.

As the previously fragmented smartphone market coalesces around big operating systems

like Apple's iPhone and Google's Android, it has become a more attractive target for

hackers seeking to maximize damage with one hit.

That's creating a big business opportunity for everyone from traditional antivirus players

like Intel's

McAfee

to

mobile

operators

like

France

Telecom

and

handset

makers

like

Nokia.

Market research firm Infonetics forecasts sales of mobile security software will grow 50

percent a year through 2014 to hit $2 billion.

fixes security holes and bugs, etc.

Updating Updated

Download your phone's

update to your mobile

device to install the patch

Back up all

the

data

and

files

on your mobile phone

Install the patch file to your

device

Turn off your mobile for 5 to

Most phones today come with suites and applications that allow a user to easily manage

and back up important data

To prevent losing important data such as contact details, calendar entries, messages, etc.,

regularly back up your phone data

A user can use third party tools and services like mobical.net to back up their mobile data

Regularly Back Up Important Data

Use Encryption to Secure Data in

Mobile DeviceEncrypt the data stored in mobile

phones such as telephone numbers,

important messages, voice calls, and

emails to keep them safe from prying

eyes

It ensures that even if the mobile phone

is lost, the data cannot be accessed

once it is encrypted

Mobile phones such as Blackberries can

encrypt data

as

a standard

feature

whereas other mobile phones require

special applications to encrypt data

Encrypting stored files on Blackberry

smartphones:

To encrypt internal files:

Turn on the Content Protection option

(Options Security Options

General Settings)

To encrypt external files:

Turn on Media Card Support (Options

Media Card or Options Memory

Media Card Support)

Set the encryption mode for the

external file system. The BlackBerry

smartphone encrypts files stored on the

media card

Choose whether to encrypt media files

in external

memory

only

on

the

BlackBerry smartphone


23/50


Enable Auto-Lock

Feature

Auto‐lock security feature allows only authorized viewing of mobile phone data

An unauthorized user cannot view or even use the phone once the auto‐lock

option is

enabled.

In

most

cases

valid

pin

number

has

to

be

entered

Navigate to your cell phone’s main menu screen

and select the icon labeled Settings

Press the OK or Home button on the keypad to

select the settings menu

Locate the Security option and press OK or

Home to select it

Scroll down and find the Auto Lock feature on

the list of security options

Press the OK or Home button on your keypad to

begin setting the auto lock feature

Choose a PIN number that you will remember to

unlock your device once the auto lock feature has

been saved

Type your four to eight digit PIN code on the

keypad. Press the Save button to save your pin, and

initiate the

auto

lock

feature

Press the End button to return to the main menu

General steps to enable auto‐lock option on mobile phones:

Smart phones today provide open platform functionality and deliver the ability to install,

remove, or update applications multiple times

The openness gives unrestricted access to mobile resources and APIs

Unrestricted access to mobile resources presents challenges and risks and unsigned

applications that

may

likely

increase

the

complexity and security risks

Install Only Signed Applications

Identify

the

files

created

on

the

phone

by

the

application

during

the

installation

Always install the applications on external storage memory cards

Do not download mobile software from any untrusted third party vendors

Ensure the quality and accountability of mobile applications by carefully

investigating the vendor

Always try

to

download

the

applications

from

the

market

place provided

by

the

mobile manufacturer

To reduce the risk of malware and installing unsigned applications,

follow the guidelines:


25/50


http://www.f ‐secure.com

http://us.mcafee.com

Install Mobile Phone AntiVirus

People may unknowingly or knowingly install the

virus (programs or .exe files) through direct or

indirect transferring

Wi‐Fi

enabled

handsets

and

Bluetooth may

let

the malware in if the antivirus is not installed

Once in the system, the virus can alter or delete

all the contact details, or crash or permanently

lock up your mobile phone applications

Antivirus software prevents, detects, and removes malware including viruses, worms, and

trojan horses

Some of the mobile antivirus software include

Norton mobile security, F‐Secure mobile security,

Kaspersky mobile

antivirus,

etc.
