- question: Delivery Optimization is downloading Windows content on my devices directly from an IP Address, is it expected?
answer: |
When Delivery Optimization downloads from a [Microsoft Connected Cache](waas-microsoft-connected-cache.md) server that is hosted by your Internet Service Provider, the download will be pulled directly from the IP Address of that server. If the Microsoft Connected cache isn't available, the download will fall back seamlessly to the CDN instead. Delivery Optimization Peers are used in parallel if available.
- question: Does Delivery Optimization use multicast? - question: Does Delivery Optimization use multicast?
answer: No. It relies on the cloud service for peer discovery, resulting in a list of peers and their IP addresses. Client devices then connect to their peers to obtain download files over TCP/IP. answer: No. It relies on the cloud service for peer discovery, resulting in a list of peers and their IP addresses.

Delivery Optimization is used by most content providers from Microsoft. A complete list can be found [here](waas-delivery-optimization.md#types-of-download-content-supported-by-delivery-optimization). Oftentimes customers may not realize the vast application of Delivery Optimization and how it's used across different apps. Content providers have the option to run downloads in the foreground or background. It's good to check any apps running in the background to see what is running. Also note that depending on the app, closing the app may not necessarily stop the download. Delivery Optimization is used by most content providers from Microsoft.

By default, peer sharing on clients using the Group download mode (option 2) is limited to the same domain in Windows 10, version 1511, and the same domain and Active Directory Domain Services site in Windows 10, version 1607. By using the Group ID setting, you can optionally create a custom group that contains devices that should participate in Delivery Optimization but don't fall within those domain or Active Directory Domain Services site boundaries, including devices in another domain. Using Group ID, you can further restrict the default group (for example, you could create a subgroup representing an office building), or extend the group beyond the domain, allowing devices in multiple domains in your organization to be peers. This setting requires the custom group to be specified as a GUID on each device that participates in the custom group.

OEMs implement the TPM as a component in a trusted computing platform, such as a PC, tablet, or phone. Trusted computing platforms use the TPM to support privacy and security scenarios that software alone can't achieve. For example, software alone can't reliably report whether malware is present during the system startup process. The close integration between TPM and platform increases the transparency of the startup process and supports evaluating device health by enabling reliable measuring and reporting of the software that starts the device. Implementation of a TPM as part of a trusted computing platform provides a hardware root of trust—that is, it behaves in a trusted way. For example, if a key stored in a TPM has properties that disallow exporting the key, that key *truly can't leave the TPM*.

The TCG designed the TPM as a low-cost, mass-market security solution that addresses the requirements of different customer segments. There are variations in the security properties of different TPM implementations just as there are variations in customer and regulatory requirements for different sectors. In public-sector procurement, for example, some governments have clearly defined security requirements for TPMs, whereas others don't.

Certification programs for TPMs—and technology in general—continue to evolve as the speed of innovation increases. Although having a TPM is clearly better than not having a TPM, Microsoft's best advice is to determine your organization's security needs and research any regulatory requirements associated with procurement for your industry. The result is a balance between scenarios used, assurance level, cost, convenience, and availability.

BitLocker provides full-volume encryption to protect data at rest. The most common device configuration splits the hard drive into several volumes. The operating system and user data reside on one volume that holds confidential information, and other volumes hold public information such as boot components, system information and recovery tools. (These other volumes are used infrequently enough that they do not need to be visible to users.) Without more protections in place, if the volume containing the operating system and user data is not encrypted, someone can boot another operating system and easily bypass the intended operating system's enforcement of file permissions to read any user data.

Without more protections in place, if the volume containing the operating system and user data is not encrypted, someone can boot another operating system and easily bypass the intended operating system's enforcement of file permissions to read any user data.
In the most common configuration, BitLocker encrypts the operating system volume so that if the computer or hard disk is lost or stolen when powered off, the data on the volume remains confidential. When the computer is turned on, starts normally, and proceeds to the Windows logon prompt, the only path forward is for the user to log on with his or her credentials, allowing the operating system to enforce its normal file permissions. If something about the boot process changes, however—for example, a different operating system is booted from a USB device—the operating system volume and user data can't be read and are not accessible. The TPM and system firmware collaborate to record measurements of how the system started, including loaded software and configuration details such as whether boot occurred from the hard drive or a USB device.

- **Hardware root of trust for measurement**. A TPM allows software to send it commands that record measurements of software or configuration information. This information can be calculated using a hash algorithm that essentially transforms a lot of data into a small, statistically unique hash value. The system firmware has a component called the Core Root of Trust for Measurement (CRTM) that is implicitly trusted. The CRTM unconditionally hashes the next software component and records the measurement value by sending a command to the TPM. Successive components, whether system firmware or operating system loaders, continue the process by measuring any software components they load before running them. Because each component's measurement is sent to the TPM before it runs, a component can't erase its measurement from the TPM. (However, measurements are erased when the system is restarted.) The result is that at each step of the system startup process, the TPM holds measurements of boot software and configuration information. Any changes in boot software or configuration yield different TPM measurements at that step and later steps. Because the system firmware unconditionally starts the measurement chain, it provides a hardware-based root of trust for the TPM measurements. At some point in the startup process, the value of recording all loaded software and configuration information diminishes and the chain of measurements stops. The TPM allows for the creation of keys that can be used only when the platform configuration registers that hold the measurements have specific values. - **Hardware root of trust for measurement**.

The Trusted Computing Group (TCG) is the nonprofit organization that publishes and maintains the TPM specification. The TCG exists to develop, define, and promote vendor-neutral, global industry standards. These standards support a hardware-based root of trust for interoperable trusted computing platforms. The TCG also publishes the TPM specification as the international standard ISO/IEC 11889, using the Publicly Available Specification Submission Process that the Joint Technical Committee 1 defines between the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).

OEMs implement the TPM as a component in a trusted computing platform, such as a PC, tablet, or phone. Trusted computing platforms use the TPM to support privacy and security scenarios that software alone cannot achieve. For example, software alone cannot reliably report whether malware is present during the system startup process. The close integration between TPM and platform increases the transparency of the startup process and supports evaluating device health by enabling reliable measuring and reporting of the software that starts the device. Implementation of a TPM as part of a trusted computing platform provides a hardware root of trust—that is, it behaves in a trusted way. For example, if a key stored in a TPM has properties that disallow exporting the key, that key truly cannot leave the TPM.

The TCG designed the TPM as a low-cost, mass-market security solution that addresses the requirements of different customer segments. There are variations in the security properties of different TPM implementations just as there are variations in customer and regulatory requirements for different sectors. In public-sector procurement, for example, some governments have clearly defined security requirements for TPMs whereas others do not.

For Windows 11, the Zero Trust principle of *verify explicitly* applies to risks introduced by both devices and people. Windows 11 provides *chip-to-cloud security*, enabling IT administrators to implement strong authorization and authentication processes with features like [Windows Hello for Business](../identity-protection/hello-for-business/index.md). IT administrators also gain attestation and measurements for determining if a device meets requirements and can be trusted. Windows 11 works out-of-the-box with Microsoft Intune and Azure Active Directory, which enable timely and seamless access decisions. Furthermore, IT administrators can easily customize Windows to meet specific user and policy requirements for access, privacy, compliance, and more.

Windows 11 provides powerful protection against credential theft with chip-level hardware security. Credentials are protected by layers of hardware and software security such as [TPM 2.0](../information-protection/tpm/trusted-platform-module-overview.md), [VBS](/windows-hardware/design/device-experiences/oem-vbs), and/or [Windows Defender Credential Guard](../identity-protection/credential-guard/credential-guard.md), making it harder for attackers to steal credentials from a device.

Windows Hello has its own PIN for sign-in, length of which can be 4 to 127 characters. Both BitLocker and Windows Hello use the TPM to prevent PIN brute-force attacks.
The TPM can be configured to use Dictionary Attack Prevention parameters ([lockout threshold and lockout duration](../../../information-protection/tpm/trusted-platform-module-services-group-policy-settings.md) to control how many failed authorizations attempts are allowed before the TPM is locked out, and how much time must elapse before another attempt can be made.

The Dictionary Attack Prevention Parameters provide a way to balance security needs with usability. For example, when BitLocker is used with a TPM + PIN configuration, the number of PIN guesses is limited over time. A TPM 2.0 in this example could be configured to allow only 32 PIN guesses immediately, and then only one more guess every two hours. This number of attempts totals to a maximum of about 4415 guesses per year. If the PIN is four digits, all 9999 possible PIN combinations could be attempted in a little over two years.

Windows includes many security features to help protect users from malware and attacks. However, trusting the Windows security components can only be achieved if the platform boots as expected and wasn't tampered with. Windows relies on Unified Extensible Firmware Interface (UEFI) Secure Boot, Early-launch antimalware (ELAM), Dynamic Root of Trust for Measurement (DRTM), Trusted Boot, and other low-level hardware and firmware security features. When you power on your PC until your anti-malware starts, Windows is backed with the appropriate hardware configuration to help keep you safe. [Measured and Trusted boot](operating-system-security/system-security/secure-the-windows-10-boot-process.md), implemented by bootloaders and BIOS, verifies and cryptographically records each step of the boot in a chained manner. These events are bound to a security coprocessor (TPM) that acts as the Root of Trust. Remote Attestation is the mechanism by which these events are read and verified by a service to provide a verifiable, unbiased, and tamper resilient report. Remote attestation is the trusted auditor of your system's boot, allowing specific entities to trust the device.
