摘要： Embodiments of the invention are directed to a firewall installer that receives a set of configuration instructions for configuring a firewall in a declarative format that describes one or more rules to be implemented by the firewall, and that automatically configures the firewall. Providing a firewall installer that is capable of configuring a firewall based upon declarative input rather than procedural process-oriented input facilitates administration of a firewall by allowing an administrator to specify desired firewall configuration at a higher, declarative level and frees the administrator from the need to specify procedures for implementing configuration changes in the firewall. In one embodiment of the invention, the firewall installer can receive and store input for configuring a firewall even when the firewall is not running, such that the firewall executes on those configuration changes when it next comes online.

摘要： A host firewall can determine and consider whether unsolicited traffic is inbound from beyond the edge of the network and allow or block such traffic based at least in part upon this characteristic. In one implementation, an edge traversal parameter can be set on a host firewall rule, which typically includes other parameters such as port, protocol, etc. If the unsolicited traffic received via an edge traversal interface matches a host firewall rule that has the edge traversal criterion, then the firewall does not block the traffic. On the other hand, if the unsolicited traffic received via an edge traversal interface fails to satisfy the edge traversal criterion on any firewall rule, then the firewall blocks the traffic.

摘要翻译： 主机防火墙可以确定并考虑来自网络边缘的未经请求的流量是否入站，并且至少部分地基于该特性来允许或阻止该流量。 在一个实现中，可以在主机防火墙规则上设置边缘遍历参数，主机防火墙规则通常包括诸如端口，协议等的其他参数。如果通过边缘遍历接口接收的未经请求的流量与具有边缘遍历的主机防火墙规则匹配 标准，那么防火墙不会阻塞流量。 另一方面，如果通过边缘遍历接口接收的未经请求的流量无法满足任何防火墙规则的边缘遍历标准，则防火墙会阻塞流量。

摘要： Computer-readable medium having a data structure stored thereon for defining a schema for expressing a network security policy. The data structure includes a first data field including data defining a parameter to be applied based on the network security policy. The network security policy defines at least one of the following: a firewall rule and a connection security rule. The data structure also includes a second data field having data specifying restrictions of the parameter included in the first data field. The parameter in the first data field and the restrictions in the second data field form the schema for expressing the network security policy to be processed. The network security policy manages communications between a computing device and at least one other computing device.

摘要： The dynamic updating of firewall parameters is described. One exemplary embodiment includes receiving a policy rule that includes a reference to a predefined container that specifies a permissible value range of at least one firewall parameter allowable under the policy rule, receiving a firewall parameter value, and populating the predefined container with the firewall parameter value if the firewall parameter value is within the permissible value range, thereby updating the policy rule.

摘要： Some embodiments of the invention are directed to techniques for determining whether a process on a computer system that is sending or receiving data, or is attempting to send or receive data, with another computer system is executing in kernel mode or user mode and providing an indicator of this determination to a security engine. In some embodiments, such an indication is provided to a security engine (e.g., a firewall) that implements a security policy based at least in part on whether the sending or receiving process is in kernel mode or user mode, and filter communications based on a process' operating mode. This enables a security engine to maintain security policies of greater specificity and thus improve security of a computer system.

摘要： A proxy service receives requests from a remote caller to configure a main service. The proxy service authenticates the caller and validates the request. The proxy service then passes the request along to the main service if the caller can be authenticated and if the request can be validated. The proxy service runs at a non-privileged level, but when the proxy service passes the request to the main service, the proxy service impersonates the caller so that the request to the main service is made at the original caller's level of privilege. The main service can block all inbound network traffic, since network requests to configure the main service are received by the proxy, which is a local object from the perspective of the main service. Additionally, the proxy can block inbound traffic other than a certain class of requests (e.g., Remote Procedure Calls).
摘要翻译： 代理服务从远程主叫方接收请求以配置主服务。 代理服务认证呼叫者并验证请求。 代理服务然后将请求传递到主服务，如果呼叫者可以被认证，并且请求可以被验证。 代理服务以非特权级别运行，但是当代理服务将请求传递给主服务时，代理服务模拟主叫方，使得对主服务的请求是在原始呼叫者的权限级别进行的。 主服务可以阻止所有入站网络流量，因为从主服务的角度看，代理服务器接收到配置主服务的网络请求，这是一个本地对象。 此外，代理可以阻止除特定类别的请求之外的入站流量（例如，远程过程调用）。
