The 13 Layers of Security on Windows Phone 8
Below is an explanation of the security provided by the 13 numbered boxes in the security architecture
diagram above:
1. Windows Phone 8 devices have to meet specific hardware requirements. This not only guarantees a
base-level user experience, it limits the hardware-related security attack vectors.
2. Windows Phone 8 has a Trusted Platform Module (TPM) 2.0 chip embedded on every device. The
TPM chip is a huge boost to security – it protects encryption keys, contains a crypto processing
engine, and is a foundational element of a secure boot chain.
3. Windows Phone 8 uses the Unified Extensible Firmware Interface (UEFI) Secure Boot industry
standard. UEFI is the new BIOS. In a UEFI Secure Boot process the firmware, the bootloader, the
kernel and kernel extensions, are all cryptographically signed. This makes it easy to detect when any
of these layers has been tampered with. If any layer in this boot process has been maliciously
altered, the device won’t boot.
4. The crypto signing goes beyond the kernel – the entire OS and every single app on the system is
code-signed to guarantee a chain of trust from the hardware all the way up
5. Windows Phone 8 uses the same NT Kernel as Windows 8 and Windows Server 2012. But it also
shares the same driver model, developer platform, security, and networking stack and graphics and
media platform. All of these have been tried and tested on more than a billion client and server
machines, many running mission-critical workloads.
6. All updates to Windows Phone 8 now come directly from, and only from, Microsoft. This helps
ensure the integrity of the OS. Also all security fixes follow the same rigorous standards set by the
Microsoft Security Response Center or MSRC for our client and server products.
7. Windows Phone 8 supports alpha-numeric and complex passwords for device-locking.
8. The internal storage on a device can now be fully encrypted using the same BitLocker technology that
ships with Windows. The BitLocker encryption key is protected by the TPM 2.0 chip and will only be
released if i) the device successfully passes the UEFI Secure Boot process to boot up a trusted OS, and
ii) if the encrypted disk is physically located in the original device. This protects data at rest and guards
against offline attacks. So it is not possible to take the encrypted storage out and get access to the
data by booting from another OS, and it is also not possible to place the encrypted storage in another
Windows Phone 8 device to access the data. This helps protect data at rest and guards against offline
attacks. With both device-lock and BitLocker enabled it is extremely difficult to gain unauthorized
access to data on the internal storage.
9. Every app runs in its own isolated chamber. Even the OS services run in their own isolated chamber.
Each app receives only the capabilities it needs to perform all its use cases. It cannot elevate its
privileges at run time, it cannot communicate with other apps on the phone other than through the
cloud, and it cannot access memory, data or the keyboard cache used by another app.
10. Even the browser runs in its own sandbox. Windows Phone 8 ships with a locked down version of
Internet Explorer 10 that does not support plug-ins, and comes with anti-phishing filters built-in.
11. To further help protect the data in each app, Windows Phone 8 provides another layer of encryption
via the Data Protection API. This is smart technology that uses entropy information already available
on the device to automatically generate new encryption keys. This way apps do not have to worry
about generating, storing and managing new keys. Each app also automatically receives its own
decryption key when it first runs.
12. However, no amount of encryption will prevent an authenticated user on a trusted device from sharing
data with unintended parties, willingly or unwillingly. This makes Information Rights Management
(IRM) critical and Windows Phone is the only smartphone platform that has IRM built-in to prevent
data leakage.
13. Finally, data synchronization with most cloud services like Office 365 and on-premise servers like
Exchange and SharePoint is done via the latest SSL 3.0 technology with AES 128 or 256 encryption.
This protects data in transit.
Note on TPM and UEFI Secure Boot standards
Microsoft is a strong believer in open standards for security, like UEFI Secure Boot and TPM. Standards
have numerous advantages over proprietary methods used by other smartphone platforms. Standards go
through a transparent development process, survive rigorous open review from the best security minds
across multiple organizations, and help ensure broad support across companies. The list of 100+
companies that define the TPM specifications can be found here and the firms behind the UEFI
specifications can be found here.
Maximize Value from Existing Microsoft Investments
The built-in IRM client on Windows Phone helps you maximize
value from your existing investments because it uses the Active
Directory Rights Management Service already available with your
Windows Servers. Exchange ActiveSync is also built-in and
supported and this is how Microsoft IT manages more than
70,000 BYOD Windows Phone devices. Additionally, a built-in
management client is available so you can use your existing
Mobile Device Management software such as MobileIron,
AirWatch, Citrix XenMobile, Symantec or Windows InTune and
System Center 2012 SP1. Finally, to further lower your TCO,
Windows Phone 8 comes with full-fidelity mobile versions of
Office so you can make the most of your existing investments in
Exchange, SharePoint, Lync and Office 365.
Windows Phone 8 works with your existing Microsoft infrastructure. Right out of the box, Windows
Phone seamlessly works with Microsoft products you know and already own, such as Exchange, Office,
SharePoint, Lync and Office 365 – no need to purchase additional third-party software.

Common Development Foundation for Client and Mobile Computing
Historically, apps for client computing devices like PCs, laptops and desktops have been developed
separately from apps for mobile computing devices like smartphones and tablets. But as more client
computing devices get touch screens and mobile broadband radios, and more mobile computing
devices take on client computing workloads, it is going to be critical for you to be able to share code
between the mobile and client computing worlds.
From an app development perspective there is deep commonality between Windows Phone 8,
Windows 8 and Windows RT. In fact, Windows Phone 8, Windows 8 and Windows RT share several
components in a common development foundation that makes it easy to port apps across different
form factors on the Windows platform.
First, Windows Phone 8, Windows 8 and Windows RT share a common development environment and
tools with Visual Studio and .NET. Second, they also share the same driver model, security model, web
browser and managed code Common Language Runtime (CLR). Finally, Windows Phone 8, Windows 8
and Windows RT all support native code and have the exact same API set for Networking, File System,
Input, Sensors, Graphics and Media, Audio, and Commerce.
Flexibility with 3 Development Models
App developers also have flexibility in how they develop apps and can choose from 3 development
models. They can write an app that uses whatever combination they desire between managed code,
native code and HTML/JavaScript code. And they can run a lot of that code across Windows Phone 8,
Windows 8 and Windows RT because of the common foundation. So porting apps and business
functionality across your mobile and client computing worlds becomes a lot faster. This will be a critical
capability needed by businesses as the worlds of mobile and client computing converge.
There are a number of programs available to help you transition your organization to Windows Phone.
