Cool Mobility in business terms is mobile productivity. It enables a workforce to have instant access to information through mobile applications anywhere, anytime. People are fundamentally changing the way they work, and in order to remain competitive, organizations are making enterprise applications accessible through mobile devices. But, what about the confidential data? How do we audit those mobile devices? This presentation will provide a streamline approach to auditing endpoint security on mobile devices.

1. The Intersection of Cool Mobility and
Corporate Protection:
Practical Steps for Assessing the Security of Mobile Devices
James Tarala, Enclave Security

2. Mobility is a Reality
• Organizations want their toys…
• These devices will not be going away anytime
soon…

3. Business Legitimacy
• Almost every industry has discovered ways of
enhancing productivity with mobility:
– Healthcare
– Financial Services
– Manufacturing
– Retail
– Government
– Professional Services
– And more…

4. What are we protecting?
• Potentially any / all of your organization’s data
• More than simply contacts & calendars
• Potentially we are protecting:
– Financial records
– Private health records
– Credit card numbers
– Anything in an email mailbox
– And much, much more…

5. What if we ignore the risk?
• The primary risk to consider is the loss of data
confidentiality
• If a mobile device is lost or stolen, the
information stored on the device is also at risk
• However, other risks include:
– Compromised authentication (SMS, soft tokens)
– Manipulation of data sets
– Impersonation of device owner

6. Mobility Statistics
• 81% of global executives say they are connected to
work through mobile devices all of the time
(Korn/Ferry International, August 2006)
• Telecommunications managers believe 28% of their
employees are using their mobile phone as their
primary work phone (IDC, June 2006)
• 85% of mobile users said it was important or very
important for mobile apps to remember their
favorites/preferences (Action Engine, September
2005)

7. Mobility Statistics (cont)
• 81% of companies surveyed reported the loss of one
or more laptops containing sensitive information
during the past 12 months (Ponemon 2010)
• 64% of companies surveyed reported that they have
never conducted an inventory of sensitive consumer
information (Ponemon 2010)
• 85% say handheld devices used in their organization
should require security protection (Bluefire Wireless
Security, April 2006)

8. Evolution of Mobile Risk
• There has been an evolution in mobile
computing
• The evolution has been from:
– Phones & PDAs
– Laptops
– Smart Phones & Tablets
• Although device capabilities have evolved,
security controls have not necessarily kept up

9. Typical Mobile Device Controls
• Generally organizations secure laptops by
implementing technical controls, such as:
– Whole disk encryption
– Anti-malware software
– Application whitelisting software
– Personal / host-based firewalls
– Strong / two-factor authentication
– Secure operating system configurations

16. More than BlackBerrys
• RIM BlackBerrys are the modern Lotus Notes
• Phrases heard from clients:
– “We went with BlackBerry because of their
security.”
– “BlackBerrys are protected by default by RIM and
BlackBerry Enterprise Servers (BES).”
• These principles apply to all mobile devices

17. So what have we learned so far?
• By default most mobile devices do not
implement even basic security controls
• Even when software is available it must be
configured, it is not “out of the box”
• Most mobile devices require not only
configuration, but owners to research & buy
additional software to gain functionality
• Centralized management is another issue
altogether…

18. Mobile Specific Threat Vectors
In addition to traditional risk vectors, mobile
devices deserve extra attention in the areas of:
– Physical theft / loss
– Wireless / Bluetooth hacking
– Geo-location tracking
– General privacy threats
– General ownership threats

19. Minimum Technical Controls
• Already, the following controls for all mobile
devices have been mentioned:
– Whole disk encryption
– Anti-malware software
– Application whitelisting software
– Personal / host-based firewalls
– Strong / two-factor authentication
– Secure operating system configurations
The Intersection of Cool Mobility and Corporate Protection © Enclave Security 2011

20. Minimum Technical Controls (cont)
• In addition, organizations should consider
controls such as:
– Functionality limitations (cameras, wireless, etc)
– LoJack / phone home
– Storage card encryption
– Remote wiping
– Remote locking
– Logging / auditing
– “Jailbreak detection”
The Intersection of Cool Mobility and Corporate Protection © Enclave Security 2011

21. Governance Questions
• In addition to technical controls, organizations
must establish policy to determine:
– Can organization data reside on personal devices?
– Who is responsible for data residing on a device?
– Will the organization purchase mobile devices for
workforce members?
– Regardless of ownership, can mobile devices be
inspected by organization personnel?
– Can data on devices be monitored by
organizational personnel?
The Intersection of Cool Mobility and Corporate Protection © Enclave Security 2011

22. Governance Questions (cont)
– Who will support mobile devices?
– Which workforce members will be offered
support?
– Will all or only certain types of devices be
supported by the organization?
– Will application support be included?
– Who is responsible installing / supporting security
software applications on devices?
– And on, and on, and on…

23. Central Management
• Laws are useful, but only when there are
sufficient mechanisms to enforce those laws
• If end users can disable controls, they will
• Technical controls help organizations to
enforce business decisions
• Therefore centralized mobile device
management must be considered

24. Commercial Enterprise Tools
• April 2011, Gartner releases a “Magic
Quadrant” study for mobile device
management software
• Evaluates security & manageability
• Names the following leaders:
– AirWatch
– Good Technology
– MobileIron
– Sybase

25. Lessons Learned
• Organizations want to use mobile devices
(even infosec groups), do not just be a barrier
• Educate business owners on specific risks and
allow them to accept it or not
• Define mandatory and optional security
controls for these devices, and stick to them
• But be willing to ban devices that do not meet
corporate standards for mobility
