NetworkIsolation/EnterpriseCloudResources

cross mark check mark check mark check mark check mark check mark

Scope:

  • Device

Contains a list of Enterprise resource domains hosted in the cloud that need to be protected. Connections to these resources are considered enterprise data. If a proxy is paired with a cloud resource, traffic to the cloud resource will be routed through the enterprise network via the denoted proxy server (on Port 80). A proxy server used for this purpose must also be configured using the EnterpriseInternalProxyServers policy. This domain list is a pipe-separated list of cloud resources. Each cloud resource can also be paired optionally with an internal proxy server by using a trailing comma followed by the proxy address. For example, <cloudresource>|<cloudresource>|<cloudresource>,<proxy>|<cloudresource>|<cloudresource>,<proxy>|.

NetworkIsolation/EnterpriseIPRange

cross mark check mark check mark check mark check mark check mark

Scope:

  • Device

Sets the enterprise IP ranges that define the computers in the enterprise network. Data that comes from those computers will be considered part of the enterprise and protected. These locations will be considered a safe destination for enterprise data to be shared to. This is a comma-separated list of IPv4 and IPv6 ranges.

ADMX Info:

  • GP English name: Private network ranges for apps
  • GP name: WF_NetIsolation_PrivateSubnet
  • GP element: WF_NetIsolation_PrivateSubnetBox
  • GP path: Network/Network Isolation
  • GP ADMX file name: NetworkIsolation.admx

For example:

10.0.0.0-10.255.255.255,157.54.0.0-157.54.255.255,
192.168.0.0-192.168.255.255,2001:4898::-2001:4898:7fff:ffff:ffff:ffff:ffff:ffff,
2001:4898:dc05::-2001:4898:dc05:ffff:ffff:ffff:ffff:ffff,
2a01:110::-2a01:110:7fff:ffff:ffff:ffff:ffff:ffff,

Scope:

Boolean value that tells the client to accept the configured list and not to use heuristics to attempt to find other subnets.

  • GP English name: Subnet definitions are authoritative

  • GP path: Network/Network Isolation

NetworkIsolation/EnterpriseInternalProxyServers

Scope:

  • Device

This is the comma-separated list of internal proxy servers. For example "157.54.14.28, 157.54.11.118, 10.202.14.167, 157.53.14.163, 157.69.210.59". These proxies have been configured by the admin to connect to specific resources on the Internet. They are considered to be enterprise network locations. The proxies are only leveraged in configuring the EnterpriseCloudResources policy to force traffic to the matched cloud resources through these proxies.

ADMX Info:

  • GP English name: Intranet proxy servers for apps
  • GP name: WF_NetIsolation_Intranet_Proxies
  • GP element: WF_NetIsolation_Intranet_ProxiesBox
  • GP path: Network/Network Isolation
  • GP ADMX file name: NetworkIsolation.admx

NetworkIsolation/EnterpriseNetworkDomainNames

Home Pro Business Enterprise Education Mobile Mobile Enterprise
cross mark check mark check mark check mark check mark check mark

Scope:

  • Device

This is the list of domains that comprise the boundaries of the enterprise. Data from one of these domains that is sent to a device will be considered enterprise data and protected These locations will be considered a safe destination for enterprise data to be shared to. This is a comma-separated list of domains, for example "contoso.sharepoint.com, Fabrikam.com".

Note

The client requires domain name to be canonical, otherwise the setting will be rejected by the client.

Here are the steps to create canonical domain names:

  1. Transform the ASCII characters (A-Z only) to lower case. For example, Microsoft.COM -> microsoft.com.
  2. Call IdnToAscii with IDN_USE_STD3_ASCII_RULES as the flags.
  3. Call IdnToUnicode with no flags set (dwFlags = 0).
