    摘要： In a computing device a domain name system (DNS) query is generated and sent, and a check is made as to whether a verified DNS response to the DNS query is received. The computing device is determined to be inside a particular network if a verified DNS response is received, and is determined to be outside that particular network if a verified DNS response is not received. A DNS response can be determined to be verified if both the DNS response has an expected value and the DNS response is digitally signed by a trusted authority, and otherwise can be determined to be not verified.

    摘要翻译： 在计算设备中，生成并发送域名系统（DNS）查询，并且检查是否接收到对DNS查询的经过验证的DNS响应。 如果接收到已验证的DNS响应，则计算设备被确定在特定网络内，并且如果未接收到经验证的DNS响应，则确定该外部在该特定网络之外。 如果DNS响应具有预期值并且DNS响应由可信管理机构进行数字签名，则可以确定DNS响应以被验证，否则可以被确定为不被验证。

    摘要： A network address of a computing device is obtained, and an unencrypted request is sent to a resource access manager of a particular network. If both a response is received from the resource access manager and the computing device has a network address within a desired range of network addresses, then a determination is made that the computing device is inside the particular network. Otherwise, a determination is made that the computing device is outside the particular network.

    摘要： Techniques to provide an improved representation of remote network access for a network administrator managing and controlling access to resources on an enterprise network. The representation indicates resources accessed by a remote computer or by a user of that computer and provides associated information useful for managing remote network access. To create the representation, multiple security associations formed between a remote client computer and resources on the enterprise network are associated with entity sessions, based on identical session identifiers generated for each security association within an entity session. The entity sessions may be aggregated into a to DirectAccess “connection” between the remote client computer and the enterprise network, based on an identity of the remote client computer. Resources accessed over the connection may be identified using a session identifier of each entity session so that security associations in that entity session may be matched with the resources.
