What Is Security?

• By its nature, security is the sum of its parts
• Security is only as good as its weakest link
• Security needs to touch all aspects of products
• It is an attribute of a system that must be
  built in
• Cannot be an after thought in the product
  process
• Security is more than encryption
• Security is about letting the good guys in and
  keeping the bad guys out
• Threats can come from unexpected vectors
• New security systems for protecting IT
  infrastructure
• What about the Air Conditioning Systems

4
Security Versus Usability

• Security is always at tension with usability
• Flexible approaches to security are required in
  the real world
• Administrators set the level of security
• Balance tradeoffs for usability
• There is no One Size Fits All approach to
  security for any system

Benefits Of Mobile Computing

• Soft Benefits
• Efficiency
• Effectiveness
• Employee satisfaction
• Hard Benefits
• Reduced staff requirements
• Reduced hardware costs
• Lower remote connectivity costs
• Reduced costs for mobile voice

7
The Value Of Mobile Data

• Different values and risks for government
• Support missions within government
• Public Safety
• Emergency Preparedness
• Public Health
• Defense
• Economy
• BlackBerry is the one tool that lets me be more
  responsive to my constituents

Mobility In The Pubic SectorUK Government
Breakdown

• 51 of Local Governments are undertaking some
  form of mobile working
• 37 of Local Governments are planning to
  introduce some form of mobile working
• 12 of Local Governments are were yet to be
  convinced

The Realities Of Providing Mobile Access To Your
Network

• What does mobility mean you?
• Your corporate network spans the globe with
  access from unknown private IP addresses
• Users your data were from every corner of the
  world
• Small, mobile computers provide full access to
  your network
• Confidential information is sent to terminals on
  insecure networks - Email, calendar,
  intranet, databases
• Users expect to be connected anytime, anyplace,
  anywhere
• These devices are outside your firewall

15
Smartphone security

• Similar risks and threats as laptops, but
• Must manage resources more efficiently
• Battery life, Network capacity
• Processor power, storage
• User Experience / Expectations are different
• These are personal computers
• They go everywhere and they will be lost, stolen
  and left behind
• Significant amounts of sensitive data
• Always connected, instant access to everything
• These devices will become targets for attackers
• Mobile malware, remote network attacks

16
Key Security Features

• Customers need standards-based
• solutions that offer
• Transport and local data encryption
• Robust application development support
• IT management and administration tools
• Malware protection/containment
• Centralized device management
• Remote lock / remote data wipe
• Remote lock and wipe capabilities
• Desktop security paradigms
• S/MIME, PGP, SSL, TLS

17
Key Security Features

• Customers need standards-based
• solutions that offer
• Multiple authentication mechanisms
• Users
• Applications
• Built-in firewalls
• Detailed logging capabilities
• Tools to enable regulatory compliance
• Service reliability and availability
• Security certification and assurance
• User education and awareness

18
What is a vulnerability?

• More commonly, we call them software
• defects, bugs, or issues
• Software defects are unavoidable in complex
  systems
• The relationships between mobile customer,
  handset, carrier network, service, and corporate
  network form a very complex system

2006

20
The threat of mobile malware

• More than 200 variants of mobile
• malware today
• Handset attacks Skulls that disable Symbian
  handsets
• Service/system attacks RedBrowser that sends
  high-value SMS messages on J2ME handsets
• New attacks growing exponentially year over
  year increasing customer awareness and concern

21
The risks of mobile malware

• For enterprises and end users
• Data leakage / loss
• Denial of service
• For carriers and service providers
• Relationships between handsets and networks can
  be exploited
• Disrupt service to a geographic area
• Interrupt an entire service/network
• Impact multiple users, regardless of handset
  vendor
• These attacks will become more sophisticated over
  time

22
How Do You Prevent Malware In Smartphones?

• Anti-Virus software typically consists of two
  parts
• Detection
• Containment
• Detection is hard
• Requires big database
• Storage space is still precious
• Requires constant updates to remain useful
• Or back end connectivity
• What if you are out of coverage?
• Or cannot turn on your radio?
• Fundamentally, how do you know ahead of time that
  something is malicious?
• Halting problem in Computer Science
• Containment is easy
• Shut down all methods to step outside a process
• Application policies and controls

23
Software Configuration Policy

• Allow the CEO to download games and let the
  Administrator sleep at night
• Contain and Control malware
• Permissions controllable by administrator and
  user
• Most secure setting enforced
• Specify Applications as Required, Optional, or
  Disallowed
• Create allowed lists and/or restricted lists
• Required applications cannot be removed by the
  user and can be automatically pushed over the air

24
Authentication In The Mobile World

• It must be an effective method
• The method must be appropriate for the situation

25
Authentication Goals

• Is the user allowed to use the device?
• Device authentication
• Is the user allowed to talk to my network?
• Network authentication
• Is the user allowed to access my service?
• Service authentication

26
Device Authentication

• Passwords
• Most common approach
• Need ability to centrally manage
• Establish for use
• Force use
• Complexity
• Timeouts
• What if the user forgets their password?
• Usability concerns
• Understand user experience

27
Device Authentication
But how do you make it easy?
28
Device Authentication

• One alternative is multi-factor authentication
• Something you know (Password, PIN, etc.)
• Something you have (Smart card, RSA token, etc.)
• Something you are (Fingerprint, Iris, etc.)

29
Can You Push Vendors To Deliver Practical
Solutions That Work

• How do you use a physical token with a mobile
  device?
• Make it wireless!
• Proximity Smart Card Reader
• IT Controlled
• Extensible by 3rd parties
• Why Wireless?
• Adds another dimension to the multi-factor
  authentication formula
• Presence

30
Starting Points For Securing Your Mobile
Deployment

• Develop A Mobile Security Policy
• Look at your existing policies today
• Desktop/laptop policy
• Internet/Acceptable use policy
• Enforce The Use of Passwords
• Understand the user experience on the device
• Small keyboard (QWERTY, SureType, T9, Virtual)
• Frequency and difficulty entering passwords
• Do alternate authentication mechanisms make
  sense?
• Require Encryption For All Data
• Data at rest as important as data in transit
• Cornerstone for protecting information outside of
  your network

31
Starting Points For Securing Your Mobile
Deployment

• Develop An Application Policy
• Standard/approved applications only
• Reduce support costs
• Manage Risks
• Contains malware risks and other data leaks
• Instant Messaging?
• Social Networking?
• Establish Auditing Requirements/Controls
• SMS
• MMS
• Phone Logs
• Develop Procurement Guidelines
• Certified Products/Vendors
• Leverage Existing Certification Framework
• CAPS, Common Criteria, FIPS
• Education and Awareness!!

  Dentists etc.)
• Meetings (Before, after and during)
• Conferences (lulls, breaks and sessions of no
  interest)
• First thing and last thing (before setting off
  and before switching off)
• Hotels
• The list is extensive but can be summarised as
  follows
• Whenever youre out of the office and have a mind
  to check your e-mail

Workflow Efficiency Benefits Significantly
Increases the efficiency of the teams back at
base. (30) BlackBerry Immediacy Benefits The
immediacy of response to urgent e-mails is of
paramount importance.
