• What are mobile devices?• Mobile device threads• BYOD• BYOD Pros and Cons • 4 Steps to design BYOD:• BYOD Strategy• Mobile Hacking techniques

demo:

1. Android Phone

2. Mobile Application Security

3. Laptop

4. Pendrives

AGENDA

• BYOD or BYOA• How to Secure the data

storages and transportation

WHAT ARE MOBILE DEVICES?

• Unauthorized Access• Infected Machine • Unreliable Application• Camera ? !• Media Storages • Mobile Phones • Internet Surfing• Network Access• Cloud ?

THREATS

• Malware• Synchronization• Phishing or SMiShing• Malicious Links or Websites

Using the personally owned mobile devices such as smart phones, IPad, Tablets , laptop, thumb drives to access organization network and corporate data such as databases, organizational software, emails…etc.

BYOD?!!!

• Cost effective:

• No need to buy lots of PC, Tablets

• Technology familiarity:• Apple users are more comfortable with apples likewise windows user are

more likely to use windows applications

• Flexibility:• Employees don’t need to carry both their personal devices and their work

needs, they can work whenever wherever they need while they have access to all data needed

BYOD PROS

Cost for employee:

• Not everybody has such devices,

• Increase usage and transportation may lead to quicker depreciation

• Repairing, upgrading or any possible accident would be under employee responsibility which is not very pleasant

BYOD CONS

Different devices:

different OS, application and quality level, which brings difficulties in managing them.

Security:

Normally companies spend a lot amount of money to buy firewalls, Anti-viruses, original application which as yearly supports and maintenance. Which employees cant afford such prices himself

BYOD CONS

Security:

while PODs contain corporate data, it can bring security risk of data leackage

Privacy issue for employee, PODs should be accessible on demand for the organization whenever they need to investigate, they might not be happy to surf internet or perform their routine daily life with that device (e.g instant messaging, calls, social networking, web browsing ,personal images….)

• What happens if an employee leave?!!!!!!!!!!

BYOD CONS (CONT…)

• Information and Communication Techonology devices ( Owned by Organization) (ICT)

• Personally Owned Device (POD)

ICT AND POD

1. Know your businesses and regulatory

2. Creating a protocol Foundation

3. Legal Right and responsibility

4. Security Concerns

4 STEPS TO DESIGN BYOD

• What does the company seek to gain from BYOD?• What unique divisions does the organization have?• What information and applications need to be accessed

by each division?• What level of security will be applied to this information?• What are the data-usage requirements for each division?

STEP 1: KNOW YOUR BUSINESSES AND

REGULATORY

Sourcing: Where did the device or softwares come from? Was it a preferred vendor or some random source?

Supporting devices: what if one individual employee uses very unknown device ?should the IT team be able to support all type of devices and vendors ?

Bandwidth: allocating bandwidth to employees based on their activity and requirement related to his responsibility at work. (high speed bandwidth for downloading?)

Business support vs. personal support: supporting all type of application although they are not related to organization routines? For financial department is it necessary to support Photoshop or 3D MAX? or Does multimedia design team need to support specific hardware?

Device Lost: what strategy do you need for a lost device? Wiping the device remotely? Detach it from network or known devices?

STEP 2: CREATING A PROTOCOL FOUNDATION

• Responsibility

The BYOD policy should determine who is responsible to protect data on the device?

• Privacy:

How much access can organization have to the private files of the employees

• Regulation and rights

Different countries and companies have their own regulation and rights

STEP 3: LEGAL RIGHT AND RESPONSIBILITY

• Device:

what kind of device , OS and hardware is accessible for organization.

• Security:

In what level security and risk are needed for each device and employee.

• Application management:

What application can be installed on the device, and assign proper level of control based on the employee requirement to perform her job

• Data access

Data access should be allocated based in a proper way, no need to give access of financial or human resource department to nonrelated departments.

STEP 4: SECURITY CONCERNS

• Individual user can only use the POD, if it has configuration and software installed with the right privilege, otherwise they just can use guest internet or network which has no access to the corporation network.

• Each POD has to have specific registered digital certificate, and it shouldn’t be copy from one POD to another POD, although devices blonge to one person

BYOD POLICY

• POD should be utilized with appropriate for of userID, Passwords and authentication devices.

• Organization has the right to investigate and control its information and device functionality, backup, retrieve, modify and deleting the corporation data , without permission of owner or user POD

BYOD STRATEGY

• All PODs should have proper Antivirus according to the Administrator management policy

• Synchronize the created or modified valuable corporate data on the POD using corporate network or using secure removable media

• All the data should be transfer through the network or media storages in encrypted form for instance :

Network (SSl or VPN)

Storage Media ( using like TrueCrypt)

BYOD STRATEGY

As organization may need to investigate the POD on demand based on the reasonable expectation, the possibility of gaining access to the personal data is high, users should be advice to store their private data in different directory with a clear name such as “private” or “personal”

BYOD STRATEGY

Before any video/audio recording inside organization should be confirmed with management Installing application on PODs should be under control of the management (such as Email Client, social networks, web browser…etc.)

Employees and administrators should be educated and aware of risks and vulnerabilities of the PODs

BYOD STRATEGY

Data that are not allowed to be stored, process, create on PODs:

• Classified secret files or above

• Highly valuable or sensitive information

• Big data such as 1Gb of corporate data on POD

BYOD STRATEGY

These strategies and policy may be different in different organization due to organization nature and functionality

BYOD STRATEGY

1- Identify the risk elements that BYOD introduces with a research group

2- Decide how to enforce policies for devices connecting to your network

3-  Build a project plan to include these capabilities: Remote device management

Application control

Policy compliance and audit reports

Data and device encryption

Augmenting cloud storage security

Wiping devices when retired

Revoking access to devices when end-user relationship changes from employee to guest

Revoking access to devices when employees are terminated by the company

BYOD SECURITY PLAN STEPS

4- Evaluation from each department chose number of users to see the

feedbacks

BYOD SECURITY PLAN STEPS

• Using hacking tools such Cain and Able • Wireshark for network sniffing • Bruteforce tools for password cracking • Sql injection or cookie injector tools for compromising

the organization database or website authentication.• Virtualization application for Anti-Forensics activity

• Demo Now

MOBILE HACKING DEVICE HACKING TECHNIQUES DEMO: LAPTOP

• Using personal data storage for backuping or running personal application or data

• Running USB live tools such as Backtrack , Helix, or • Live CD/DVD OS which has illegal tools such as

Dropbox, google Drive,….for accessing the or stealing data.

• Usually USB or live CD/DVD tools can be utilized for Anti-Forensics activity

• Personal VPN to hide their activity

• Demo …… now

MOBILE HACKING DEVICE HACKING TECHNIQUES DEMO: MEDIA STORAGE

• Bring Your Own Device = Bring Your Own Application• Downloading unknown applications or downloading

application from untrusted appstores such as cracked tools can brings malwares as a gift to the organization.

• Employees show be limited in downloading application which is beyond the BYOD policy list

• Mobile phones should not be rooted or jailbreak• Application should be download from trusted app

markets such as official Apple app-store or google Play or Microsoft app-store.

BYOD OR BYOA

• all the data storages must encrypt corporate data• Just legitimate user can leave organization with

corporation data• All data transfer through network should be encrypted

via SSL or VPN which belongs to organization

HOW TO SECURE DATA ON BYOD

MOBILE APPLICATION SECURITY

• Network Spoofer / Dsicovery [Need root access]• Shark for root ( like Wireshark on PC) [Need root access]

• TcpDump• Ettercap • dSploit• dDoS tool for Mobile Devices• Bluetooth Cloning • DroidShip • etc
