# Windows 10, version 1709, connection endpoints for non-Enterprise editions
**Applies to**
- Windows 10 Home, version 1709
- Windows 10 Professional, version 1709
- Windows 10 Education, version 1709
In addition to the endpoints listed for [Windows 10 Enterprise](manage-windows-endpoints.md), the following endpoints are available on other editions of Windows 10, version 1709.
We used the following methodology to derive these network endpoints:
1. Set up the latest version of Windows 10 on a test virtual machine using the default settings.
2. Leave the devices running idle for a week (that is, a user is not interacting with the system/device).
3. Use globally accepted network protocol analyzer/capturing tools and log all background egress traffic.
4. Compile reports on traffic going to public IP addresses.
5. The test virtual machine was logged in using a local account and was not joined to a domain or Azure Active Directory.
> [!NOTE]
> Microsoft uses global load balancers that can appear in network trace-routes. For example, an endpoint for *.akadns.net might be used to load balance requests to an Azure datacenter, which can change over time.

In addition to the endpoints listed for [Windows 10 Enterprise](manage-windows-endpoints.md), the following endpoints are available on other editions of Windows 10, version 1803.

>Beginning with Windows 10 version 1607 and Windows Server 2016, this policy setting is no longer used by Windows, but it continues to appear in GPEdit.msc for compatibility with previous versions. Beginning with Windows 10 version 1703, the default value is 5. This value is implemented during provisioning so that another Windows component can either delete it or take ownership of it, depending on the system configuration. For TPM 2.0, a value of 5 means keep the lockout authorization. For TPM 1.2, it means discard the Full TPM owner authorization and retain only the Delegated authorization.
This policy setting configures how much of the TPM owner authorization information is stored in the registry of the local computer. Depending on the amount of TPM owner authorization information that is stored locally, the Windows operating system and TPM-based applications can perform certain actions in the TPM that require TPM owner authorization without requiring the user to enter the TPM owner password.
This policy setting configured which TPM authorization values are stored in the registry of the local computer. Certain authorization values are required in order to allow Windows to perform certain actions.

There are three TPM owner authentication settings that are managed by the Windows operating system. You can choose a value of **Full**, **Delegate**, or **None**.
- **Full**   This setting stores the full TPM owner authorization, the TPM administrative delegation blob, and the TPM user delegation blob in the local registry. With this setting, you can use the TPM without requiring remote or external storage of the TPM owner authorization value. This setting is appropriate for scenarios that do not require you to reset the TPM anti-hammering logic or change the TPM owner authorization value. Some TPM-based applications may require that this setting is changed before features that depend on the TPM anti-hammering logic can be used.

Some TPM-based applications may require that this setting is changed before features that depend on the TPM anti-hammering logic can be used. Full owner authorization in TPM 1.2 is similar to lockout authorization in TPM 2.0. Owner authorization has a different meaning for TPM 2.0.

# Microsoft network client: Digitally sign communications (always)
**Applies to**
- Windows 10
- Windows Server
Describes the best practices, location, values, policy management and security considerations for the **Microsoft network client: Digitally sign communications (always)** security policy setting.
Describes the best practices, location, values, policy management and security considerations for the **Microsoft network client: Digitally sign communications (always)** security policy setting for SMBv3 and SMBv2.
## Reference
The Server Message Block (SMB) protocol provides the basis for file and print sharing and many other networking operations, such as remote Windows administration. To prevent man-in-the-middle attacks that modify SMB packets in transit, the SMB protocol supports the digital signing of SMB packets.
This policy setting determines whether SMB packet signing must be negotiated before further communication with the Server service is permitted.
Implementation of digital signatures in high-security networks helps prevent the impersonation of client computers and servers, which is known as "session hijacking." But misuse of these policy settings is a common error that can cause data loss or problems with data access or security.
Implementation of digital signatures in high-security networks helps prevent the impersonation of client computers and servers, which is known as "session hijacking." But misuse of these policy settings is a common error that can cause data access failure.
If server-side SMB signing is required, a client device will not be able to establish a session with that server, unless it has client-side SMB signing enabled. By default, client-side SMB signing is enabled on workstations, servers, and domain controllers. Similarly, if client-side SMB signing is required, that client device will not be able to establish a session with servers that do not have packet signing enabled. By default, server-side SMB signing is enabled only on domain controllers.
Beginning with SMBv2 clients and servers, signing can be either required or not required. If this policy setting is enabled, SMBv2 clients will digitally sign all packets. Another policy setting determines whether signing is required for SMBv3 and SMBv2 server communications: [Microsoft network server: Digitally sign communications (always)](microsoft-network-server-digitally-sign-communications-always.md).
If server-side SMB signing is enabled, SMB packet signing will be negotiated with client computers that have SMB signing enabled.
There is a negotiation done between the SMB client and the SMB server to decide whether signing will effectively be used. The following table has the effective behavior for SMBv3 and SMBv2.
Using SMB packet signing can impose up to a 15 percent performance degradation on file service transactions.
| | Server – Required | Server – Not Required |
|---|-------------------|-----------------------|
| **Client – Required** | Signed | Signed |
| **Client – Not Required** | Signed <sup>1</sup> | Not Signed<sup>2</sup> |
</br>
<sup>1</sup> Default for domain controller SMB traffic</br>
<sup>2</sup> Default for all other SMB traffic
There are three other policy settings that relate to packet-signing requirements for Server Message Block (SMB) communications:
- [Microsoft network server: Digitally sign communications (always)](microsoft-network-server-digitally-sign-communications-always.md)
- [Microsoft network client: Digitally sign communications (if server agrees)](microsoft-network-client-digitally-sign-communications-if-server-agrees.md)
- [Microsoft network server: Digitally sign communications (if client agrees)](microsoft-network-server-digitally-sign-communications-if-client-agrees.md)
Performance of SMB signing is improved in SMBv2. For more details, see [Potential impact](#potential-impact).
### Possible values
- Enabled
- Disabled
- Not defined
### Best practices
1. Configure the following security policy settings as follows:
- Disable **Microsoft network client: Digitally sign communications (always)**.
- Disable [Microsoft network server: Digitally sign communications (always)](microsoft-network-server-digitally-sign-communications-always.md).
- Enable [Microsoft network client: Digitally sign communications (if server agrees)](microsoft-network-client-digitally-sign-communications-if-server-agrees.md).
- Enable [Microsoft network server: Digitally sign communications (if client agrees)](microsoft-network-server-digitally-sign-communications-if-client-agrees.md).
2. Alternately, you can set all of these policy settings to Enabled, but enabling them can cause slower performance on client devices and prevent them from communicating with legacy SMB applications and operating systems.
Enable **Microsoft network client: Digitally sign communications (always)**.

### Vulnerability
Session hijacking uses tools that allow attackers who have access to the same network as the client device or server to interrupt, end, or steal a session in progress. Attackers can potentially intercept and modify unsigned Server Message Block (SMB) packets and then modify the traffic and forward it so that the server might perform objectionable actions. Alternatively, the attacker could pose as the server or client computer after legitimate authentication, and gain unauthorized access to data.

SMB is the resource-sharing protocol that is supported by many Windows operating systems. It is the basis of many modern features like Storage Spaces Direct, Storage Replica, and SMB Direct, as well as many legacy protocols and tools. SMB signatures authenticate users and the servers that host the data. If either side fails the authentication process, data transmission does not take place.
### Countermeasure
Configure the settings as follows:
Enable **Microsoft network client: Digitally sign communications (always)**.
- Disable **Microsoft network client: Digitally sign communications (always)**.
- Disable [Microsoft network server: Digitally sign communications (always)](microsoft-network-server-digitally-sign-communications-always.md).
- Enable [Microsoft network client: Digitally sign communications (if server agrees)](microsoft-network-client-digitally-sign-communications-if-server-agrees.md).
- Enable [Microsoft network server: Digitally sign communications (if client agrees)](microsoft-network-server-digitally-sign-communications-if-client-agrees.md).
In highly secure environments, we recommend that you configure all of these settings to Enabled. However, that configuration may cause slower performance on client devices and prevent communications with earlier SMB applications and operating systems.
>**Note:**  An alternative countermeasure that could protect all network traffic is to implement digital signatures with IPsec. There are hardware-based accelerators for IPsec encryption and signing that could be used to minimize the performance impact on the servers' CPUs. No such accelerators are available for SMB signing.

No such accelerators are available for SMB signing.
 
### Potential impact
Implementations of the SMB file and print-sharing protocol support mutual authentication. This prevents session hijacking attacks and supports message authentication to prevent man-in-the-middle attacks. SMB signing provides this authentication by placing a digital signature into each SMB, which is then verified by the client and the server.
Implementation of SMB signing may negatively affect performance because each packet must be signed and verified. If these settings are enabled on a server that is performing multiple roles, such as a small business server that is serving as a domain controller, file server, print server, and application server, performance may be substantially slowed. Additionally, if you configure devices to ignore all unsigned SMB communications, older applications and operating systems cannot connect. However, if you completely disable all SMB signing, computers are vulnerable to session-hijacking attacks.
Storage speeds impact performance. A faster drive on the source and destination allows more throughput, which causes more CPU usage of signing. If you are using a 1 Gb Ethernet network or slower storage speed with a modern CPU, there is limited degradation in performance. If you are using a faster network (such as 10 Gb), the performance impact of signing may be greater.

To enable client-side SMB packet signing, set [Microsoft network client: Digitally sign communications (if server agrees)](microsoft-network-client-digitally-sign-communications-if-server-agrees.md). Devices that have this policy set will not be able to communicate with devices that do not have server-side packet signing enabled. By default, server-side packet signing is enabled only on domain controllers. Server-side packet signing can be enabled on devices by setting [Microsoft network server: Digitally sign communications (if client agrees)](microsoft-network-server-digitally-sign-communications-if-client-agrees.md).
Beginning with SMBv2 clients and servers, signing can be either required or not required. If this policy setting is enabled, SMBv2 clients will digitally sign all packets. Another policy setting determines whether signing is required for SMBv3 and SMBv2 server communications: [Microsoft network client: Digitally sign communications (always)](microsoft-network-client-digitally-sign-communications-always.md).
If server-side SMB signing is required, a client device will not be able to establish a session with that server, unless it has client-side SMB signing enabled. By default, client-side SMB signing is enabled on workstations, servers, and domain controllers. Similarly, if client-side SMB signing is required, that client device will not be able to establish a session with servers that do not have packet signing enabled. By default, server-side SMB signing is enabled only on domain controllers.
There is a negotiation done between the SMB client and the SMB server to decide whether signing will effectively be used. The following table has the effective behavior for SMBv3 and SMBv2.
If server-side SMB signing is enabled, SMB packet signing will be negotiated with client devices that have SMB signing enabled.
| | Server – Required | Server – Not Required |
|---|-------------------|-----------------------|
| **Client – Required** | Signed | Signed |
| **Client – Not Required** | Signed <sup>1</sup> | Not Signed<sup>2</sup> |
</br>
<sup>1</sup> Default for domain controller SMB traffic</br>
<sup>2</sup> Default for all other SMB traffic
Using SMB packet signing can impose up to a 15 percent performance degradation on file service transactions.
There are three other policy settings that relate to packet-signing requirements for Server Message Block (SMB) communications:
- [Microsoft network client: Digitally sign communications (always)](microsoft-network-client-digitally-sign-communications-always.md)
- [Microsoft network client: Digitally sign communications (if server agrees)](microsoft-network-client-digitally-sign-communications-if-server-agrees.md)
- [Microsoft network server: Digitally sign communications (if client agrees)](microsoft-network-server-digitally-sign-communications-if-client-agrees.md)
Performance of SMB signing is improved in SMBv2. For more details, see [Potential impact](#potential-impact).
### Possible values
- Enabled
- Disabled
- Not defined
### Best practices
1. Configure the following security policy settings as follows:
- Disable [Microsoft network client: Digitally sign communications (always)](microsoft-network-client-digitally-sign-communications-always.md).
- Disable **Microsoft network server: Digitally sign communications (always)**.
- Enable [Microsoft network client: Digitally sign communications (if server agrees)](microsoft-network-client-digitally-sign-communications-if-server-agrees.md).
- Enable [Microsoft network server: Digitally sign communications (if client agrees)](microsoft-network-server-digitally-sign-communications-if-client-agrees.md).
2. Alternately, you can set all of these policy settings to Enabled, but enabling them can cause slower performance on client devices and prevent them from communicating with legacy SMB applications and operating systems.
Enable **Microsoft network server: Digitally sign communications (always)**.

Session hijacking uses tools that allow attackers who have access to the same network as the client device or server to interrupt, end, or steal a session in progress. Attackers can potentially intercept and modify unsigned Server Message Block (SMB) packets and then modify the traffic and forward it so that the server might perform objectionable actions. Alternatively, the attacker could pose as the server or client device after legitimate authentication and gain unauthorized access to data.
SMB is the resource-sharing protocol that is supported by many Windows operating systems. It is the basis of NetBIOS and many other protocols.

SMB is the resource-sharing protocol that is supported by many Windows operating systems. It is the basis of many modern features like Storage Spaces Direct, Storage Replica, and SMB Direct, as well as many legacy protocols and tools. If either side fails the authentication process, data transmission does not take place.
### Countermeasure
Configure the settings as follows:
Enable **Microsoft network server: Digitally sign communications (always)**.
- Disable [Microsoft network client: Digitally sign communications (always)](microsoft-network-client-digitally-sign-communications-always.md).
- Disable **Microsoft network server: Digitally sign communications (always)**.
- Enable [Microsoft network client: Digitally sign communications (if server agrees)](microsoft-network-client-digitally-sign-communications-if-server-agrees.md).
- Enable [Microsoft network server: Digitally sign communications (if client agrees)](microsoft-network-server-digitally-sign-communications-if-client-agrees.md).
In highly secure environments we recommend that you configure all of these settings to Enabled. However, that configuration may cause slower performance on client devices and prevent communications with earlier SMB applications and operating systems.
>**Note:**  An alternative countermeasure that could protect all network traffic is to implement digital signatures with IPsec. There are hardware-based accelerators for IPsec encryption and signing that could be used to minimize the performance impact on the servers' CPUs. No such accelerators are available for SMB signing.

### Potential impact
Implementations of the SMB file and print-sharing protocol support mutual authentication. This prevents session hijacking attacks and supports message authentication to prevent man-in-the-middle attacks. SMB signing provides this authentication by placing a digital signature into each SMB, which is then verified by the client and the server.
Implementation of SMB signing may negatively affect performance because each packet must be signed and verified. If these settings are enabled on a server that is performing multiple roles, such as a small business server that is serving as a domain controller, file server, print server, and application server, performance may be substantially slowed. Additionally, if you configure computers to ignore all unsigned SMB communications, older applications and operating systems cannot connect. However, if you completely disable all SMB signing, devices are vulnerable to session-hijacking attacks.
Storage speeds impact performance. A faster drive on the source and destination allows more throughput, which causes more CPU usage of signing. If you are using a 1 Gb Ethernet network or slower storage speed with a modern CPU, there is limited degradation in performance. If you are using a faster network (such as 10 Gb), the performance impact of signing may be greater.

# SMBv1 Microsoft network client: Digitally sign communications (always)
**Applies to**
- Windows 10
This topic is about the Server Message Block (SMB) v1 protocol. SMBv1 is not secure and has been deprecated in Windows. Beginning with Windows 10 Fall Creators Update and Windows Server, version 1709, [SMBv1 is not installed by default](https://support.microsoft.com/help/4034314/smbv1-is-not-installed-by-default-in-windows).
The rest of this topic describes the best practices, location, values, policy management and security considerations for the **Microsoft network client: Digitally sign communications (always)** security policy setting only for SMBv1. The same policy setting can be applied to computers that run SMBv2. For more information, see [Microsoft network client: Digitally sign communications (always)](microsoft-network-client-digitally-sign-communications-always.md).
## Reference
The Server Message Block (SMB) protocol provides the basis for file and print sharing and many other networking operations, such as remote Windows administration. To prevent man-in-the-middle attacks that modify SMB packets in transit, the SMB protocol supports the digital signing of SMB packets.
This policy setting determines whether SMB packet signing must be negotiated before further communication with the Server service is permitted.
Implementation of digital signatures in high-security networks helps prevent the impersonation of client computers and servers, which is known as "session hijacking." But misuse of these policy settings is a common error that can cause data loss or problems with data access or security.
If server-side SMB signing is required, a client device will not be able to establish a session with that server, unless it has client-side SMB signing enabled. By default, client-side SMB signing is enabled on workstations, servers, and domain controllers. Similarly, if client-side SMB signing is required, that client device will not be able to establish a session with servers that do not have packet signing enabled. By default, server-side SMB signing is enabled only on domain controllers.
If server-side SMB signing is enabled, SMB packet signing will be negotiated with client computers that have SMB signing enabled.
Using SMB packet signing can impose up to a 15 percent performance degradation on file service transactions.
There are three other policy settings that relate to packet-signing requirements for Server Message Block (SMB) communications:

- [Microsoft network server: Digitally sign communications (if client agrees)](smbv1-microsoft-network-server-digitally-sign-communications-if-client-agrees.md)
### Possible values

## Policy management
This section describes features and tools that are available to help you manage this policy.
### Restart requirement
None. Changes to this policy become effective without a device restart when they are saved locally or distributed through Group Policy.
## Security considerations
This section describes how an attacker might exploit a feature or its configuration, how to implement the countermeasure, and the possible negative consequences of countermeasure implementation.

- Disable [Microsoft network client: Digitally sign communications (always)](smbv1-microsoft-network-client-digitally-sign-communications-always.md).
- Disable **Microsoft network server: Digitally sign communications (always)**.
- Enable [Microsoft network client: Digitally sign communications (if server agrees)](smbv1-microsoft-network-client-digitally-sign-communications-if-server-agrees.md).
- Enable [Microsoft network server: Digitally sign communications (if client agrees)](smbv1-microsoft-network-server-digitally-sign-communications-if-client-agrees.md).
2. Alternately, you can set all of these policy settings to Enabled, but enabling them can cause slower performance on client devices and prevent them from communicating with legacy SMB applications and operating systems.

## Policy management
This section describes features and tools that are available to help you manage this policy.
### Restart requirement
None. Changes to this policy become effective without a device restart when they are saved locally or distributed through Group Policy.
## Security considerations
This section describes how an attacker might exploit a feature or its configuration, how to implement the countermeasure, and the possible negative consequences of countermeasure implementation.
### Vulnerability
Session hijacking uses tools that allow attackers who have access to the same network as the client device or server to interrupt, end, or steal a session in progress. Attackers can potentially intercept and modify unsigned Server Message Block (SMB) packets and then modify the traffic and forward it so that the server might perform objectionable actions. Alternatively, the attacker could pose as the server or client device after legitimate authentication and gain unauthorized access to data.
SMB is the resource-sharing protocol that is supported by many Windows operating systems. It is the basis of NetBIOS and many other protocols. SMB signatures authenticate users and the servers that host the data. If either side fails the authentication process, data transmission does not take place.
### Countermeasure
Configure the settings as follows:
- Disable [Microsoft network client: Digitally sign communications (always)](smbv1-microsoft-network-client-digitally-sign-communications-always.md).
- Disable **Microsoft network server: Digitally sign communications (always)**.
- Enable [Microsoft network client: Digitally sign communications (if server agrees)](smbv1-microsoft-network-client-digitally-sign-communications-if-server-agrees.md).
- Enable [Microsoft network server: Digitally sign communications (if client agrees)](smbv1-microsoft-network-server-digitally-sign-communications-if-client-agrees.md).
In highly secure environments we recommend that you configure all of these settings to Enabled. However, that configuration may cause slower performance on client devices and prevent communications with earlier SMB applications and operating systems.
>**Note:**  An alternative countermeasure that could protect all network traffic is to implement digital signatures with IPsec. There are hardware-based accelerators for IPsec encryption and signing that could be used to minimize the performance impact on the servers' CPUs. No such accelerators are available for SMB signing.
 
### Potential impact
Implementations of the SMB file and print-sharing protocol support mutual authentication. This prevents session hijacking attacks and supports message authentication to prevent man-in-the-middle attacks. SMB signing provides this authentication by placing a digital signature into each SMB, which is then verified by the client and the server.
Implementation of SMB signing may negatively affect performance because each packet must be signed and verified. If these settings are enabled on a server that is performing multiple roles, such as a small business server that is serving as a domain controller, file server, print server, and application server, performance may be substantially slowed. Additionally, if you configure computers to ignore all unsigned SMB communications, older applications and operating systems cannot connect. However, if you completely disable all SMB signing, devices are vulnerable to session-hijacking attacks.

# Microsoft network server: Digitally sign communications (if client agrees)
# SMBv1 Microsoft network server: Digitally sign communications (if client agrees)
**Applies to**
- Windows 10
Describes the best practices, location, values, policy management and security considerations for the **Microsoft network server: Digitally sign communications (if client agrees)** security policy setting.
This topic is about the Server Message Block (SMB) v1 protocol. SMBv1 is not secure and has been deprecated in Windows. Beginning with Windows 10 Fall Creators Update and Windows Server, version 1709, [SMBv1 is not installed by default](https://support.microsoft.com/help/4034314/smbv1-is-not-installed-by-default-in-windows).
The rest of this topic describes the best practices, location, values, policy management and security considerations for the **Microsoft network server: Digitally sign communications (if client agrees)** security policy setting only for SMBv1. The same policy setting can be applied to computers that run SMBv2. For more information, see [Microsoft network server: Digitally sign communications (if client agrees)](microsoft-network-server-digitally-sign-communications-always.md).
