2 Gartner delivers the technology-related insight necessary for our clients to make the right decisions, every day.

3 Small Incidents are Common

4 Agenda Whats really new about risks for mobile devices? Controls you may put on your list of requirements What about user experience? How do mobile security architectures compare? Why and when would you improve on existing platform security controls?

5 Gartner for Technical Professionals Whats really new about risks for mobile devices?

6 Threat Agents Malware Threat type: logical Coexists with user Examples: Redsn0w Jailbreak Android FoncyDropper ZitMo Thief Threat type: physical Exclusive access Example: Plenty in the room 5 Evil maid Threat type: physical Coexists with user Examples: Stealing a file system

7 Old risks, in new context 6 Impact Likelihood Thief Malware It is only a matter of time before the first large data breach concerning a mobile device receives media attention Impact Likelihood Expanding use cases and storage capacity Increased popularity

8 Impact on Security Architecture The security risks to information have not changed: -Malicious software -Theft/loss of the device -Eavesdropping But there are new twists: -Endpoint ownership -No dominant operating system or paradigm -Very short device life cycle -Immature management and security tools -Usability and network connectivity

9 Impact on Security Architecture Risk Management No data on device Controls in the Apps (Container) Controls on the device Management None Manage the device (required for certificates) i.e. MDM Limited (manage container only) Connectivity Required On-line only Offline Application/ User Experience VDI/Web app/App w/ remote data Resident App (dev/COTS) w/security Resident App (dev/COTS) w/o security Native Apps Example 1 – No Data on the Device

10 Impact on Security Architecture Risk Management No data on device Controls in the Apps (Container) Controls on the device Management None Manage the device (required for certificates) i.e. MDM Limited (manage container only) Connectivity Required On-line only Offline Application/ User Experience VDI/Web app/App w/ remote data Resident App (dev/COTS) w/security Resident App (dev/COTS) w/o security Native Apps Example 2 – Data within a Container Only

11 Impact on Security Architecture Risk Management No data on device Controls in the Apps (Container) Controls on the device Management None Manage the device (required for certificates) i.e. MDM Limited (manage container only) Connectivity Required On-line only Offline Application/ User Experience VDI/Web app/App w/ remote data Resident App (dev/COTS) w/security Resident App (dev/COTS) w/o security Native Apps Example 3 – Data on the Device

12 Gartner for Technical Professionals Controls you may put on your list of requirements

13 Access Control Consider -Methods: PIN, password, swipe, face unlock, hardware token, other biometrics -Policies to enforce: password complexity/history/delay/lock, inactivity timer -Risks of keyloggers and other spyware -Limitations facing laboratory attacks that circumvent authentication 12 Aims to reduce the risk of Thieves and Evil Maids by preventing direct logical access to device

14 Encryption Aims to reduce the risk of Thieves and Evil Maids by preventing logical access to extracted information Consider Encryption and keys in hardware/software Keys derived from device and/or passcode? What information is encrypted? Cache management Known weaknesses and third party validations

15 Application Controls 14 Aim to reduce the risk of Malware and Evil Maids by preventing direct logical access to applications and their data Consider Application and data isolation Signatures Key management and encryption APIs Management hooks Application store controls Kill switch: remotely kill an application on all devices App Data

16 Remote and Local Wipe Aims to reduce the risk of Thieves by remotely or locally wiping applications and data Consider -Full/partial wipe -Local/remote wipe -What information and apps are wiped -The wiping method -How to confirm completion 15

17 Gartner for Technical Professionals What about user experience?

18 Lets keep sensitive information off the device entirely! 17 An example: Client Virtualization No controls needed on the device Connection secured with encryption User authenticated prior to access …But malware, keyloggers, and jailbroken devices may be a problem

19 Access to Information Secure Time-to-market Manageability Rich and Immersive UX Offline Native Capabilities Portability

20 Comparison Assessment 19 *You are responsible for building your own security controls! *

21 Broader Impact: Network Architecture Increasing radio spectrum consumption -An increasing number of Wi-Fi devices will consume more of your spectrum (Wi-Fi devices > humans) -S L O W networks are not user-friendly -Even unauthorized Wi-Fi devices consume spectrum as they scan for Wi-Fi networks Solutions include -Selective site survey, mission-critical network design -Capacity planning, n APs -Intrusion detection systems, spectrum monitoring Same goes for WAN and WWAN

22 Gartner for Technical Professionals (AKA Know your platforms before adding more stuff) How do mobile security architectures compare?

23 Android Security Type: End-user control Key elements -Linux process and file isolation -Permissions based Concerns: -Fragmentation of the platform over OEMs -Encryption support dependent on OEM -Content providers accessible by default -Many OSS components and uncurated appstores may lead to malware -Permissions rely on peoples judgment 22

24 iOS Security Type: Walled garden Key elements: -Curated Appstore -Sandboxing -Hardware encryption, always on -OTA updates Concerns: -Vulnerabilities in OS that lead to jailbreak -Few mechanisms that limit the access of an app -Data protection not used by all applications and not validated 23

25 BlackBerry Security Type: Guardian Key elements -Best in class mobile management and security -Data protection capabilities -No jailbreaks for BB smartphones Concerns -AppWorld is vetted but its use not mandated, leading to potential for malware -Apps may have extensive access, without jailbreak -Management is critical, e.g. encryption is optional 24

26 Application Controls for Various Platforms PlatformApplication testing Centralized signing Application control on the device Third-party anti-malware products BlackBerry Yes, but applications can be offered outside of App World Yes, but the requirement to check the signature is configurable Yes iPhone Yes Limited to major applications No Windows Phone 6.x YesYes, but the requirement to check the signature is configurable Available through third-party products or System Center Yes Windows Phone 7 YesYes, but the requirement to check the signature is configurable No Symbian Yes Available through third-party products Yes Android Limited – some app stores perform testing but apps available outside of app stores No Yes

27 Gartner for Technical Professionals Recommendations

28 Understand the risks and the threats you are trying to protect against and accept that some risks cannot be mitigated Limit support to handhelds that satisfy minimal security requirements Balance UX with security and connectivity Users will go around security if you dont have a good UX Conduct data analysis to determine what is acceptable on the device and what is not Deal with related infrastructure issues: network, authentication, provisioning, …
