Risk management in Windows Phone

Protecting data at rest

Preventing access to

confidential information

by a 3rd party

This is normally

achieved by device lock, remote wipe

and encryption of the data

Lack of manageability

and key exposure

GOAL CONTROLS WEAKNESSES

Data at rest: data protection

Device LockUsing simple PIN or alphanumeric passwordManageable with Exchange ActiveSync

Remote Wipe

Mechanisms to help protect dataSD card is secured via the standard SD lock mechanismFiles system spans the device flash and the SD cardNo phone file system access from a PC or a 3rd party app running on the phoneZune software does not sync of documents or e-mail

Data leak prevention with IRM e-mail and RMS

Data at rest: Windows Phone storage

Single partition HD model files system

SD cards are locked via a standard SD card lock mechanism

Unique 128-bit key pairs the SD card to the phone Removing the card will reset the phone and wipe all data

Access to the SD card is prevented from any another device

SD controller on the card will prevent access to the card unless the correct 128-bit password is supplied

Protecting against malware

Preventing malware tools

to highjack the system or access data

This is normally

achieved by certification

and anti-malware service

Jailbreak, verifiability,

and time sensitive

GOAL CONTROLS WEAKNESSES

Protection from malware

.xap

Phone only installs .xap packages signed by marketplace

Phone handles all aspects of .xap installation based on the manifest

Users control install, update, and uninstall, while the marketplace controls revocation

Individual apps cannot make arbitrary changes to the phone during installation

Individual apps do not control their own lifecycle on the phone

Applications and

licenses

Phone only runs apps that have a valid marketplace licenseApps are sandboxed into separate security accounts while installed and at runtimeResource allocation policy keeps the foreground app responsive and ensures the user can always use Start to run a new app

Secure access

Preventing access to

confidential information by

a 3rd party snooping on

the wire

This is normally achieved

with VPN, and other

authentication mechanisms

Complexity to users and

manageability

GOAL CONTROLS WEAKNESSES

Access

HTTP and HTTPS – 128-bit or 256-bit SSLWi-Fi – Open, WEP, WPA (PSK, ENT) and WPA2 (PSK, ENT), HiddenBluetooth 2.1 (Microsoft driver only)

Beta Distribution ServiceDistribute pre-certified apps to an access-controlled set of beta usersCapabilities:

Developer selects list of testers (up to 100) based on Windows Live IDDeveloper sends an email to testers with a private deep-link to the application Only testers selected in App Hub can test the application and provide feedback for 90 daysDeveloper can end beta period before 90 daysBeta cannot be updated

Benefits:No need to unlock phones to test appsEnables developers to build higher quality appsApp does not need to be certified first

Targeted Distribution ServiceDistribute certified apps privately to a targeted set of usersSelect ‘hidden’ in the Test step of app submission to enable Targeted distributionCapabilities:

Developer needs to get the app certified before distributingDeveloper sends an email with a deep-link to the users (App is not discoverable via Search)Developer can update the app, which is pushed to the usersNo limits on the number of users or duration (no time-bombing)No access enforcement,Apps can be ‘free’ or ‘paid’Apps can be published publicly at any time

Benefits:Enables broad distribution of apps in a targeted way Enables broad public previews and community distribution
